2.2 Regulations

If you violate the following regulations, you may lose your entitlement for benefits. In addition, we cannot be held liable for any damage resulting from such violations.

2.2.1 Intended use

The FINOCAM A5 has been designed for easy to medium machining work in the dental sector. ➤ Only process materials that you can select in

FINOCAM. Only use the machine commer cially.

➤ Before creating jobs, verify if the objects being

prepared may be utilized at the place of use according to local and/or national regulations or other authorized organisations or entities (e. g. professional associations, health authorities). In particular, verify if the material is approved for the machined object type and if the object type is designed in accordance with applicable regulations. Neither the manufacturing software nor the CNC machine will inform you about possible regulatory infringements, but will executes jobs in accordance with the preferences and materials set by the user.

➤ Verify that each object type and each material in

your jobs are authorized to manufacturing materials. If mandated by local or national regula tions, obtain relevant authorization from the responsible organisation or entities (e. g. professional associations, health authorities).

3.5 Air extraction concept

The air extraction concept consists of:

• Air that is emitted from the spindle and the bellow

• The external air extraction system (suction device, suction hose, optional switching unit)

• The vacuum sensor

During job execution, the machine constantly blows air into the working chamber (➲ Fig. 7, upper arrows).

An external suction device that you connect to the CNC machine with a suction hose extracts the machining debris from the working chamber (➲ Fig. 7, lower arrow). This concept decreases the soiling and wear of sensitive machine parts.

 The air extraction system does not replace the

regular cleaning of the machine. Without regular cleaning, the machine life decreases signifi cantly.

Through the air extraction, a vacuum develops in the working chamber which is constantly monitored by a vacuum sensor (display in FINOCNC:

➲ chapter

4.9). If the vacuum is too weak, machining is not

possible. If the vacuum becomes too weak during a running job, FINOCNC interrupts machining until the vacuum is sufficient again (➲ chapter 5.7). The current strength of the vacuum displays in FINOCNC (➲ chapter 4.9 or in documentation for the manufacturing software).

5.2 Job execution overview

Damaging of the machine when using damaged tools or workpieces

If tools or workpieces are damaged, parts can break off and damage the machine during job execution. ➤ Check the workpieces and tools thoroughly for

damage before every job execution. Carrying out a typical job with the FINOCAM A5 is as follows:

1. Create a job in FINOCAM

2. Insert the tools into the machine

3. Insert the workpieces into the machine

4. Execute the job in FINOCNC The steps in the manufacturing software are described in the corresponding documentation. The following text describes how to perform manual work with the CNC machine.

NOTICE

ENU

5.3 Inserting/changing tools

Damaging of the spindle or the tool positions if you use improper tools

Improper tools can damage the collet chuck of the spindle and/or the tool positions. ➤ Only use tools with a sufficiently large chamfer

at the tool shank.

➤ Install a retaining ring as a stop ring according to

DIN 471-A3.

➤ Only insert tools with a maximum diameter of

3 mm at the thickest part into the collet chuck.

➤ Only insert tools with a maximum cutting edge

diameter of 2.6 mm into the tool changer.

 We recommend original tools as they are desig-

ned especially for the designated jobs.

You can insert up to 16 tools into the tool changer. The machine can change tools automatically during machining so that it executes jobs without your interference.

Fig. 19: Tool changer positions in the working chamber of

the machine (marked orange)

You can equip the tool changer in two ways:

• Via the spindle – you insert a tool into the collet

chuck and the spindle will deposit the tool in the

tool changer. This function is described in the

documentation for the manufacturing software.

• By inserting the tools into the tool changer

manually. This is described below. You insert the tools manually as follows: S1. Start FINOCNC. S2. Call up the job execution view and select the job

that you want to execute from the job list. ➡ FINOCNC displays the tools that are assigned to

the job in the lower part of the application win -

dow. M3. Open the front cover.

5.7.3 How to proceed in case of a tool breakage

If a tool breaks during machining, the machine will not recognize this immediately and the spindle will continue until the next tool change. Only upon measuring the broken tool will the job execution be cancelled and FINOCNC will display a corresponding message. A tool breakage can be caused by the following:

• The tool was damaged or worn.

• The tool was put into the wrong tool changer position or was inserted into the spindle manually at the wrong time. As a consequence, it was not suitable for the processing step.

• The distribution of the objects in the workpiece (“nesting”) was not sufficiently adapted to the material.

M1. Open the front cover. M2. Remove all parts of the broken tool from the

working chamber.

M3. If the spindle picked up the tool from the tool

changer, check if the tool was inserted into the correct position. Insert a spare tool into the correct position in the tool changer (➲ chapter 5.3).

M4. If you inserted the tool into the collet chuck

manually, check if the broken tool corresponds to the initial tool type in which FINOCNC prompted. Have a correct spare tool ready.

M5. Close the front cover and execute the job again.

 If tools break regularly, you can find additional

information in the chapter on troubleshooting (➲ chapter 8).

ENU

5.7 Operation interruption or abortion of job execution

An operation interruption can occur because the compressed air supply or the vacuum in the working chamber is not sufficient. An

interrupted

job will normally be resumed automatically after the error is corrected. The job execution is

aborted

in the following cases:

• In case of a machine malfunction

• In case of a tool breakage

• In case of a power failure

If a job was

aborted

, you have to execute it again in

FINOCNC.

5.7.1 How to proceed in case of an operation interruption

If the job execution was interrupted, FINOCNC displays a corresponding message. M1. If FINOCNC prompts that the compressed air is

insufficient, check the following:

• The manometer of the service unit

The installation of the pneumatic hoses

• Your compressor M2. If FINOCNC prompts that the vacuum in the wor-

king chamber is insufficient, check the suc tion hose and your suction device.

 You will find additional information in the chapter

on troubleshooting (➲ chapter 8).

5.7.2 How to proceed in case of a machine malfunction

FINOCAM

4 Introduction

4.1 The concept of FINOCAM

In order to mill or grind with your CNC machine of the Impression series, you first create jobs in FINOCAM. These jobs contain all necessary information like, for example, the objects to be machined and their placement in the workpieces (blanks / grinding blocks). FINOCAM uses the information to calculate all data necessary for job execution. Afterwards, FINOCAM transfers the calculated data to FINOCNC. FINOCNC controls the CNC machine and executes the jobs. Jobs can be executed independently from calculations. For grinding jobs you need a suitable CNC machine. You may also need the optional wet grinding option. When we describe grinding jobs in these intructions for use, we assume that you use the required equipment. If you do not process grinding jobs, ignore the corresponding information.

4.2 Intended use

 Only use FINOCAM to calculate jobs for CNC machines that you can select in the

application settings or that the application can read from a dongle ( page 17).  Only use the application on a fully PC compatible device under a supported

operating system ( page 8).  Always use the newest version of FINOCAM that is released for your CNC

machine and operating system. You receive the newest version from customer

support or via the update function of FINOCNC. All other uses are not intended. FINO GmbH cannot be held reliable for damage resulting from misuse.

5 The user interface

FINOCAM has a window for the application settings and a window for job processing. The whole job processing is done in this one window. Only for some functions does an own window open. In order to use the many functions of the application, you open different views through an icon bar in the header of the application window. Every view contains control elements for one specific area of job processing.

 You also call up the window for the application settings through the icon bar.

This window has its own icon bar ( page 23).

The icon bar in the window for job processing:

Illustration 3: The icon bar in the window for job processing

The icons open the following sections (from left to right):

• View for the workpiece archive

• View for importing STL files

• Nesting view

• View for placing bars and drops

• View for editing empty areas

• Window for calculating jobs

• Window for the application settings

The last icon has no function meant for the user.

 To open a view or a window, click on the corresponding icon.  The application colours the chosen icon blue. Compare the icon for the nesting

view above ( Illustration 3).

6 Starting and setting up FINOCAM

After installation it is recommended to adjust the application settings according to your working environment and conditions. You usually configure the settings only once. If necessary, however, you can change the settings at any time. It requires a restart for the application to apply any of our changes.

You start and configure FINOCAM as follows:  You have installed the application completely.

S 1. Start FINOCAM as follows:

• Through the desktop icon (if installed)

• Through the file FINOCAM.exe in the installation folder.

 The program window for job processing displays. S 2. Click on the depicted icon in the icon bar.

 The Settings window opens.

6.1 Adjusting the general settings

 You have called up the Settings window. S Click on the depicted icon in the icon bar.

 The view for the general settings displays.

Specifying the interface language S From the Language drop-down list select the language for the user interface.

Manually specifying the machine type

Incorrect job execution if the wrong machine type is chosen

If you specify the wrong type for the CNC machine which is executing the jobs, the application will calculate the job data incorrectly. This leads to an incorrect job execution.

 If possible, have the machinetype read from the dongle.  If choosing the machine type manually, make sure to select the right type.

If you calculate jobs for multiple CNC machines with one computer, specify the corresponding machine type for the next job before the actual calculation.

S 1. Deactivate the Read machine type from dongle check field. S 2. From the machine type drop-down list select the type of CNC machine for

which you want FINOCAM to calculate the job data.

Configuring technical settings

In the middle area of the current window you mainly find technical settings. S To activate or deactivate one of these settings, click on the corresponding check

field.

IMPORTANT

NOTICE

IMPORTANT

You find descriptions of these settings in the following table:

Activating or deactivating the display of the import options

When you import STL data, FINOCAM can perform the following operations:

• Height optimization

• Search for divergent insertion vectors

• Search for drillings

 The search for divergent insertion vectors and for drillings are only performed

when using a CNC machine with 5 axes.

These operations can either always be performed or you can specify for every individual object, which operations you want to be performed. The latter option allows you to save computer processing time (➲ page 36). S If you want to decide on a per object basis which operations are performed, turn

on the “import options” by activating the Show

import options check field.

 Beside the import options, FINOCAM also shows value bars for the 5-axis

release for outer surfaces if you use a 5-axis machine.

S If you want the mentioned actions to always be performed, deactivate the Show

import options check field.

Check field Setting activated Setting deactivated Presetting /

Recommendation

Do not save data for error handling

FINOCAM only writes data necessary for job execution.

When calculating job data, FINOCAM writes additional data which can help service technicians with troubleshooting

Deactivated

Only activate this setting on request from customer service, because it may cause a huge amount of data being created on your hard drive.

Automatically quit after installation

After FINOCAM has completed the job calculation, it shuts down.

After the job calculation the user interface is shown again. The calculation itself is always done in the background.

Deactivated

Activate this setting if you do not need the application directly after job calculation.

Read machine type from dongle

FINOCAM reads the machine type from the dongle. After the next application start you see the retrieved value in the current window beside the Machine type drop-down list.

FINOCAM uses the machine type which you select in the current window in the Machine

type drop-down list.

Activated

Activate this setting for safety reasons. If choosing the wrong machine type, the jobs will be calculated incorrectly.

Different scaling in X, Y, Z

When creating a workpiece, you can specify individual values for the X, Y and Z axis.

The scaling factor is always identical for all axes.

Deactivated

Only activate this setting if you work with materials which need different scaling factors.

ENU

Specifying the default processing status of calculated objects

Through the 3 option fields in the Status of calculated objects area you specify the default status which is assigned to already calculated objects. S Activate the option field next to the desired status:

• Do not process

The application assigns the processing status “do not process” to already

calculated objects. The objects will not be machined again if the job is executed

in the CNC machine once more. They function as “place holders”.

• Process

The application assigns the processing status “process” to already calculated

objects. The objects will be machined again if the job is executed in the CNC

machine once more.

• Already processed

The application assigns the processing status “already processed” to already

calculated objects. The corresponding areas are shown as non-usable empty

areas.

You find further information about the processing status of objects in the chapter on placing objects (➲ page 37).

Activating or deactivating workpieces and materials for wet grinding S If you use the optional wet grinding module, activate the Wet grinding module

available check field. Only then will the corresponding workpieces and materi-

als be available.

Saving the settings S Save your changes by clicking on the depicted icon in the bottom right corner of

the window.

6.2 Specifying the processing settings

In the processing settings you specify for each material individual settings regarding the following topics:

• Bars

• Drops

• Oversize of fits

• Used tools

• Processing order

You specify the processing settings the following way:  You have called up the Settings window (➲ page 17).

S Click on the depicted icon in the icon bar.  The view for the processing settings displays.

S 2. From the Material selection list on the left side of the window, select the

material whose settings you want to adjust.

S 3. On the right side, specify the setting for the selected material as desired.

Specifying the settings for bars S 1. Adjust the calculation of bars in the Bars area through the following 3 value bars:

• Diameter of node

Specify the diameter of node. The node is the starting point of the bar and always lies on the border of an object.

• Opening angle

The opening angel specifies with how many degree the bar opens from the node towards the material border.

Illustration 4: Left: Nodes, Right: Opening angles

• Reducing remaining areas

Specify by how many percent the bars will be reduced if the finishing type

Reduce bars is selected.

S 2. In the Oversize of fits area use the Cavity and Drillings value bars to specify

the oversize of fits in millimetres for the cavity and drillings.

Specifying used tools S 1. In the Optional tools area if for the selected material tools should be used that

deviate from the standard:

• Roughing with 1.5 mm flat ground cutter

This check field is only displayed for the materials PMMA (burn), wax and model plaster. Per standard your CNC machine uses a radius cutter (2 mm) for roughing. To save milling time, you can use a flat grinded cutter 1.5 mm) for the mentioned material instead.

• Finish drillings with 1.2 mm flat ground cutter

Per standard your CNC machine uses a radius cutter (1 mm) for drillings. If you want to use a flat grinded cutter (1.2 mm) in addition to finish drillings, activate this check field. This allows you to precisely carve out 90° angles.

S 2. To finish drillings, cavities and fissures with a radius cutter (0.6 mm), activate the

following check fields:

• Finish drillings with 0.6 mm radius cutter

• Finish cavities with 0.6 mm radius cutter

• Use 0.6 mm radius cutter for fissures

IMPORTANT

Specifying diameter of drops

You can have drops conically taper. This prevents the tool from damaging the drop during job processing. S In the Diameter of drops area at the bottom of the window specify the diameter

of drops directly at the object (value bar D0) and at the remaining material

(value bar D1). D0 may not be less than D1 If your input violates this rule, FINOCAM equalizes the values of D0 and D1.

Specifying the sequence optimization S Specify through the Sequence optimization drop-down list if you want the

tools or the objects to determine the work order during job execution. For this

select between the entries Parallel processing and Individual processing:

• Parallel processing

The tools determine the work order during job processing. First, the CNC machine processes

all

objects with

one

tool and then changes to the next tool until all objects are fully processed with all required tools. The following diagram illustrates this work order using an example of 2 objects and 2 tools:

Illustration 5: Parallel processing

Advantage of this work order: The processing time of the job is reduced because the tools do not have to be changed too often. Disadvantage of this work order: No object will be finished before the whole job is completed.

• Individual processing

The objects determine the work order during job processing. The CNC machine processes

every

object

completely

with all tools before starting with the next object. The following diagram illustrates this work order using an example of 2 objects and 2 tools:

IMPORTANT

ENU

Illustration 6: Individual processing

Advantage of this work order: You can stop the CNC machine during job execution to check the processing quality by visually inspecting the already fully completed objects. Do not remove the workpieces from the CNC machine during visual inspection. Even a slight deviation of positioning when inserting the workpieces again will result in the machine not finishing the job correctly. Disadvantage of this work order: Longer processing time because the machine has to change tools frequently.

Specifying the machining sequence S Specify the processing order of the objects within one workpiece through the

Machining sequence drop-down list:

• DirectMill optimized

FINOCAM determines the optimal calculation and processing order for the object in each individual workpiece.

• From left to right

The CNC machine starts with the most left hand object and ends with the most right hand object.

• From smallest to largest object

The CNC machine starts with the smallest object and ends with the largest.

• According to the list

The CNC machine processes the objects according to the import list from top to bottom. You create the import list in the view for importing STL files (➲ page 26).

6.3 Specifying the data transfer settings

 You have called up the Settings window ( page 17).

S 1. Click on the depicted icon in the icon bar.

 The view for the data transfer settings display.

S 2. In the Archive folder text field enter the folder, where you want the data for the

individual jobs to be stored.

S 3. In the Folder for storing processing data enter the folder, where you want

the calculated job data to be stored. FINOCNC reads the data for job execution from this folder.

7 Creating workpieces and selecting them for editing

In this chapter we guide you step by step through a typical workflow of creating a new or administrating an existing job. Follow this guide especially during your first milling and grinding jobs. The workflow described here comprises the following points among others:

• Creating or loading a workpiece

• Choosing the material for new workpieces

• Importing STL data for the individual objects

• Placing objects in the workpieces

• Adding bars

• Calculating the job data

Using the workpiece archive

At the beginning of job processing you either create a new workpiece or select a stored one from the archive.  You have started FINOCAM. S 1. If the Settings window is open, close it. Restart FINOCAM to apply your

changes.

S 2. Click on the depicted icon in the icon bar.  The workpiece archive view displays. There you also create new workpieces.

If you want to edit an existing workpiece, continue with the designated chapter ( page 25).

7.1 Creating a new workpiece

You create workpieces in the New workpiece area. S 1. From the Material drop-down list select the material you want to process.

If you select a grinding material, your choice applies to all grinding blocks that you insert into the block holder for the corresponding job. Therefore, only use grinding blocks of the same material for one job.

Illustration 7: Selecting a material for a new workpiece

 If you use the optional wet grinding module and want to create a grinding job,

but the corresponding materials are missing in the list, check if you activated the Wet grinding module available check field in the general application settings ( page 17).

 FINOCAM displays default values for the selected material in the Dimensions

and Height drop-down lists.

IMPORTANT

S 2. For grinding blocks select the size in the Dimension drop-down list. The drop-

down list displays the different sizes as designated by the corresponding manufacturer.

 For blanks the drop-down list only contains the default diameter of 98.5 mm.

You cannot change this value.

S 3. For blanks select the height in the Height drop-down list.

 For grinding blocks the height is determined by the block type which you select-

ed in the Dimensions drop-down list. Therefore, you cannot change the Height value for grinding blocks.

S 4. In the Scaling input field enter in how far FINOCAM should compensate for the

shrinking during sintering when placing objects in the workpiece.

Example: 1.25. S 5. If necessary, enter a lot number into the Lot number input field. S 6. If necessary, enter a comment for the job into the Comment input field.

Use comments for your notes about the job. S 7. Click on the depicted icon below the Comment input field.  FINOCAM assigns a unique ID number to the workpiece and adds a workpiece

card into the workpiece archive. This card appears at the first position below

the text Workpiece archive. The card contains a thumbnail of the workpiece as

well as several job details.

 The colour of the workpiece helps you to recognize the material. For example,

zirconium oxide is displayed as white and PMMA as yellow.

Illustration 8: Workpiece cards in the archive: On the left with a Blank, on the right with a grinding block.

The data on the workpiece cards from top to bottom:

• ID number

• Material

• Dimensions

• Height

• Lot number (if entered, otherwise you see a blank line)

• Scaling factor

Because the new workpiece is now in the archive, you can now select it for processing.

ENU

7.2 Selecting a workpiece from the archive

To process workpieces, you first select them in the workpiece archive. If you select a previously used workpiece, you can place additional objects onto the unprocessed areas, allowing you to use the workpiece further.

Illustration 9: Workpiece cards in the archive

 In this view you can also start the calculation of workpieces. As the job calcula-

tion is the last step of job processing, you find the description of this function later in these instructions for use ( page 45).

 You have called up the workpiece archive which contains at least one workpiece

card.

S 1. If the desired workpiece card is not shown on the first page of the archive, use

the scroll bar at the right border of the window to search through the whole archive. If your archive is very large, we recommend using the filter (see below).

S 2. To edit a workpiece, click on the depicted icon in the corresponding workpiece

card.

 If you selected a workpiece with

existing objects, the application switches

to the STL file import. There you can import STL files containing objects ( page 26).

If you selected a workpiece

with

existing objects, the application switches directly to

the nesting view. In this view you can move the existing objects ( page 26).

Using the filter in the workpiece archive

In order to only show workpieces that meet certain criteria, use the filter in the Filter area. As soon as you change a filter criterion, FINOCAM adjusts the displayed workpiece cards immediately. Note that all criteria are optional. S 1. In the Material selection list mark the desired material. Selecting the entry All

removes the filter.

S 2. In the Dimensions selection list mark the desired dimension of the workpiece.

Selecting the entry All removes the filter. S 3. In the Height selection list mark the desired height of the workpiece. Selecting

the entry All removes the filter. S 4. Enter the ID number of the desired workpiece into the ID input field.

As every ID can only occur once, you only filter out

one

single workpiece with this criterion. However, FINOCAM continues to apply the other filter criteria as well so that the desired workpiece may not display. Therefore, we recommend removing the other filter criteria so that they do not prevent the desired workpiece from being shown.

S 5. Enter a lot number into the Lot number input field. S 6. Enter a combination of characters into the Comment input field which has to

occur in the comment field of the desired workpiece. This function also finds combinations of characters within words. It is not case sensitive. This function does not search comments for keywords but only for exact combinations of characters. For example, if you enter “Bridge zirconium oxide”, this text has to occur in the comment field of a workpiece

exactly like this

for the workpiece to display in the archive. It is not sufficient if only “Bridge” or “Zirconium oxide” or “Zirconium oxide Bridge” occurs in the comment field.

7.3 Deleting a workpiece from the archive

 You have called up the archive.

S 1. To delete a workpiece and with it the job, click on the depicted icon in the

corresponding workpiece card.

S 2. Confirm the safety prompt in the window that opens.  FINOCAM immediately deletes the workpiece from the archive.

8 Importing STL files

In order to place objects in a workpiece, you first have to import the corresponding STL files into FINOCAM. The import of STL files is done in the following steps:

IMPORTANT

ENU

FINOCAM offers two options to select STL files:

• Via a file browser which you use to navigate to the desired files. When selecting files this way, you are very flexible, however, file selection takes a bit of time.

• Via a root directory into which you copy all STL files. FINOCAM only offers you the files in the root directory, which allows to select files quickly. However, you are limited to the files in the root directory.

Which option you choose is only a matter of your preference and does not affect the job editing in FINOCAM. You can switch between the two options at any time.

Calling up the view for importing STL files

If you selected an empty workpiece in the archive, the view for importing STL files will display directly and you can skip the following step.  You have selected a workpiece for editing. S Click on the depicted icon in the icon bar.  The view for importing STL files displays.

the top (left) and from the side (right).

 If the application does not show one or both images, the corresponding preview

has been disabled.

8.2 Importing STL files via a root directory

If you want to import STL files via a root directory, you first have to specify the directory. You can change it at any time. If you change the root directory regularly, selecting files via the file browser may be the faster option ( page 27).

8.2.1 Specifying the root directory

S 1. In the top right corner click on the depicted icon.

 The window for selecting the root directory opens.

and hold the left mouse button:

• You “draw” sinter bars along the object.

• When adjusting sinter plates, you drag the end points until the surface meets your requirements.

• You “draw” sinter bars with connected end points along the object. When you are finished, FINOCAM connects the end points automatically.

IMPORTANT

S 4. Set the height of the bar or plate in millimetres via the Height slider. S 5. Set the width of sinter bar ins millimetres via the Width slider.

The volume of the sinter bar or sinter plate should equal the volume of the object.

S 6. Click on the depicted icon.  The window for placing sinter bars and sinter plates closes. FINOCAM stores

your input.

8.6 Selecting the type of an object

You specify the type of an object so that the application can calculate it correctly.  You have selected a file in the view for importing STL files.

S In the Object type selection list mark the appropriate type.  If the 5 axis release outer surface value bars display, they are set to the

default value for the selected object type.

 The value bars only display if the Show import option check field is activated

in the general application settings and if you are editing a job for a machine with 5 axes. ( page 17).

The object type will be indicated by an icon in the import list after the import. Which icon stands for which entry in the Object type selection list can be found in the description of the import list. ( page 33).

8.7 Specifying the processing quality (precision)

FINOCAM can calculate objects with different levels of precision. The lower the precision/quality, the faster the calculation and the execution in the CNC machine. The selected level of quality affects the distance between the milling paths on the outer surfaces. Fits, however, are always calculated with the same accuracy. You activate or deactivate this function as follows:  You have selected a file in the view for importing STL files. S Click on the depicted icon(s) as often as until the icon displays the desired

number of stars. They indicate 3 different levels of quality:

• 1 star = fast

• 2 stars = standard

• 3 stars = optimal

8.8 Specifying the 5-axis release of an object

 The value bars only display if the Show import option check field is activated

in the general application settings and if you are editing a job for a machine with 5 axes. ( page 17).

With the two value bars in the 5 axis release outer surface area you specify to what degree the rotary axes of the CNC machine will be slanted in order to machine the undercuts on the outer surfaces. The maximum angle is 15°. The Occlusal value bar affects the top angle when machining object. The Cavity value bar affects the bottom angle when machining objects.

IMPORTANT

ENU

Illustration 16: Left: occlusal; Right: cavity

You use the function as follows:  You have selected a file in the view for importing STL files.

S 1. Specify the desired angle through the Occlusal value bar. S 2. Specify the desired angle through the Cavity value bar.

8.9 Specifying the import options

Through the import functions you specify how FINOCAM processes the data files for job execution. FINOCAM only shows the import options if the Show import options check field is activated in the general application settings ( page 23). In addition, some of the import options also require a 5-axis machine. S To activate or deactivate an import option, click on the corresponding icon.  The icon changes and indicates the new status. You normally deactivate import options to save computer processing time during the import. We recommend activating the import options for all objects. FINOCAM offers the following import options (left icon – the corresponding option is activated, right icon – the corresponding option is deactivated):

Height optimization

By default, objects are vertically centered within the workpiece with a setting angle of 0°. If you activate the height optimization, FINOCAM automatically checks whether the object is too high for the selected workpiece. If this is the case, the application tries to place the object in the workpiece nevertheless by altering the setting angle.

Search for divergent insertion vectors (only for 5-axis machines)

If activated, FINOCAM automatically checks whether the insertion vectors of the object are parallel to each other or if they are divergent. If they are divergent, the job will be executed with 5 axes.

Search for drillings in objects (only for 5-axis machines)

If activated, FINOCAM automatically checks whether the current object has drillings and uses the result during job calculation.

IMPORTANT

8.10 The import list

The import list contains all imported objects before they are added to the job.

8.10.1 Adding an object to the import list

 You have selected a file in the view for importing STL files and specified the

import options.

S 1. Click on the depicted icon.  FINOCAM adds the current object to the import list.

S 2. Check whether the application shows a green icon next to the height value of the

new entry. In this case the height of the work piece is sufficient for processing the object. If the icon is red, the object is too high for the workpiece.

S 3. In case of a red icon, move the object vertically ( page 29). If this is not suc-

cessful, you have to create a different job for the object with a higher workpiece.

8.10.4 Adding the import list to the job

In order to place objects in the workpiece, you add them to the job. As soon as you have added objects to the job, you can no longer change their import options. If you want to change the import options of an already imported object nonetheless, you have to remove it from the job and re-import it with the desired options.  The import list contains the desired objects. S 1. Click on the depicted icon.  If at least one object is too high for the workpiece, you receive a corresponding

message. S 2. If objects are too high: To add them to the job nonetheless, click on the depicted

icon on the left. In order to cancel the import for

all

objects, click on the depicted

icon on the right.  If you actually added objects to the job, FINOCAM immediately switches to the

view for placing objects in the work piece (the “nesting view”).

 In order to add additional objects to the job, call up the view for importing STL

data again and repeat the steps described above.

9 The nesting view: Placing objects in the workpiece

To place imported objects in the workpiece of the current job, you use the nesting view. You can place an object only once per import. If you want to use an object multiple times, import the corresponding STL file as often as required.

Calling up the nesting view

If you added objects to the job via the import list, FINOCAM shows the nesting view automatically and you can skip the following step. S Click on the depicted icon in the icon bar.  The nesting view displays.

The workpiece display

On the right hand side of the nesting view you find the workpiece display which shows the workpiece with all imported objects. FINOCAM automatically places new objects in the middle of the workpiece display. From there you move them to the desired place. To use most of the surface area of blanks and to correctly position bars in grinding blocks, you also rotate the objects. If you are editing a job that was already executed in the machine before, you may see black areas in the display view. These areas contain already machined objects and therefore cannot be used again. You can, however, place objects on the remaining unused areas to further use the partially processed workpiece. In the chapter on editing empty areas is described how to unlock the black areas to place objects on them again ( page 35).

imported object.

S 1. To move an object, position your mouse above the corresponding illustration in

the workpiece display, press and hold the left mouse button and “drag” the object to the desired spot. Then release the mouse button. If objects overlap too much or exceed the workpiece border, the application marks the affected areas in red. In addition, you receive a warning message in the top left corner of the workpiece display. If you do not correct this incorrect placement, you cannot calculate the job!

IMPORTANT

S 2. If necessary, rotate the objects to the left or the right:

• Rotating in steps of 1°:

Press and hold the mouse button and press <ARROW KEYS UP> or

<ARROW KEYS DOWN>.

• Rotating in steps of 5°:

• Press and hold the mouse button and press <ARROW KEYS LEFT> or

<ARROW KEYS RIGHT>.

• Rotating in steps of 90°:

Press and hold the mouse button and press <STRG+ARROW KEYS LEFT> or

<STRG+ARROW KEYS RIGHT>.

9.2 Special requirements when placing objects in grinding blocks

FINOCAM automatically places one bar in every grinding block. It runs from the left side of the object to the block holder. FINOCAM determines the size of the bar on the basis of the size of the object.

Insufficient adhesion of bars due to wrong placement

If bars are placed on concave surfaces and/or surfaces with too little material thickness, the adhesion of the bars may be insufficient.  Before placing the objects, check their surface on the basis of the STL data and

rotate them in the nesting view so that bars are only placed on convex surfaces

of sufficient height. Read more information on this elsewhere ( chapter 10.5,

page 42).

You do not see the automatically placed bar in the workpiece display.

Illustration 20: Object in a grinding block with drawn in bar (in black)

Keeping safety distances

When placing objects in grinding blocks, you have to keep safety distances on the left and on the right side. On the left margin of the block you may not exceed the two lines. On the right margin of the block keep a short safety distance.

Illustration 21: Drawn in safety distances

The snap-to placement aid places objects in workpieces in the best possible way. For more information read the next section.

NOTICE

HINT

Using the snap-to placement aid

With the snap-to placement aid positioning of objects in grinding blocks is fast and optimized for a correct job execution. If you activate this aid, the application places the objects into a fixed, optimized position within the grinding blocks as soon as you drag them onto a block. You can then only move objects

between

but not

within

grinding blocks. The objects are anchored

to the individual blocks.

Illustration 22: Object in a grinding block places with the snap-to placement aid

When the snap-to placement aid is deactivated, you place the objects freely with your mouse ( page 49).

For high quality grinding results use the placement aid. Especially after rotating objects, you should “drag” them a short distance

within the grinding block

if the placement aid is activated. The application then places the objects into an optimized position.

Activating and deactivating the snap-to placement aid

 You are currently editing a grinding block.

S Click on the depicted anchor icon in the top left corner of the workpiece display.

 FINOCNC toggles between activated and deactivated placement aid. Blue icon

9.3 Specifying the processing status of objects

Through the thumbnails in the list with imported objects, you change the processing status of the individual objects. The colours of the illustrations change depending on the selected machining state.

Illustration 23: Specifying the processing status

S Click as often on the thumbnail of the corresponding object as until the desired

processing status displays. You find the available processing statuses and the corresponding colours in the table below.

 FINOCAM colours the thumbnail and the object in the workpiece display in the

colour of the selected processing status.

IMPORTANT

9.4 Removing objects from jobs

S To remove an object from a job, assign the processing status “deleted” to it.

 FINOCAM removes the object from the workpiece display immediately. In the list

of objects, however, the object will still be listed until you call up the job in the workpiece archive again.

10 Setting bars and drops

After having placed objects in the workpiece, you set the required bars and drops for milling jobs. For grinding jobs there is exactly one bar per grinding block which is set automatically by the application ( page 37 and  page 42). Therefore you cannot call up the view for settings bars and drops when editing grinding jobs.

Insufficient adhesion due to an incorrect placement of bars

If you place bars into the wrong position, their adhesion may be insufficient.  Note the important information on setting bars

( chapter 10.4, page 42)

depicted icons:

• None (left icon) – The bar will not be further machined after finishing

(it displays white in the workpiece display)

• Reduce (middle icon) – The bar will be reduced after finishing

(it displays yellow in the workpiece archive)

• Remove (right icon) – The bar will be removed after finishing

(it displays orange in the workpiece display)

If you do not select a finishing type, the application assigns the preselected option None.

 The selected icon displays in blue.

You can also change the finishing type after setting a bar by pressing <STRG> ( page 44). To save time, we recommend specifying the finishing type

before

setting a bar.

S 2. Click on the depicted icon. S 3. In the workpiece display click on the spot at the border of the desired object,

where you want to set the bar.  FINOCAM places the bar at the desired spot in the workpiece display.

 The active bar always displays in dark blue. As soon it is no longer active, its

S2. Press <STRG> as often as until the desired finishing type is selected. The blue

icon in the side panel indicates which finishing type is currently selected.

10.3 Moving bars vertically

By default, FINOCAM places bars with minimum distance above the equator of an object. If necessary, you can vertically move the bar. For this you adjust the height of the node (starting point of the bar) or of the end point of the bar. To do this, use the side view in the left side panel.

Illustration 26: Side view: Object with bar

A: Node B: End point C: Bar

If you set the node and the end point to a different height, FINOCAM positions the bar askew in the workpiece.

Specifying the height of the node and the endpoint

If you want the height of the node and of the end point to be different, adjust the height of the node first. When you do this, FINOCAM positions the bar parallel to the equator. Therefore, if you moved the endpoint before the node, this change would be reverted. S 1. Position the mouse pointer above the node [A] in the side view.  The mouse pointer takes the depicted shape. S 2. Press and hold the left mouse key and “drag” the point upwards or downwards.

 a) FINOCAM positions the bar parallel to the equator of the object.

b) The height of the whole bar adjusts to the height of the node. c) The line in the table associated with the bar changes: The value in the Z1

table column contains the new height of the node.

S 3. Release the mouse button. S 4. To position the bar askew in the workpiece, position the mouse pointer over the

endpoint in the side view [B].

 The mouse pointer takes the depicted shape. S 5. Press and hold the left mouse button and “drag” the point upwards or

downwards.

 a) FINOCAM moves the endpoint and positions the bar accordingly.

b) The line in the table associated with the bar changes: The value in the Z2

table column contains the new height of the node.

S 6. Release the mouse button.

10.4 Moving bars horizontally

S 1. In the workpiece display click on the desired bar and press and hold the left

mouse button.

S 2. „Drag“ the bar to the desired spot. S 3. Release the mouse button.

10.5 Important information on setting bars

For a successful job execution you have to place bars correctly. Regard the following information. You check the objects’ surfaces on the basis of the STL models by using a suitable application. FINOCAM comes with an STL viewer which you can use to view STL files directly on the computer that is running FINOCAM. You find more information about this in the chapter on installing FINOCAM (➲ page 7).

10.5.1 Placing bars on convex surfaces of sufficient height

When editing milling jobs as well as grinding jobs, you should place bars at convex surfaces with a sufficient material thickness. This prevents too low adhesion of the bars. Additionally, subsequent manual works may be required otherwise. For grinding jobs the position of the single bar is fixed. Therefore you influence the location where the bar touches the object by rotating the object ( page 36). In the following illustration of an inlay the material thickness on the left side is too low to place a stable bar. However, the right side is suitable.

Illustration 27: STL model of an inlay with drawn in bars

To take this into account e.g. when placing an object for a grinding job, you rotate the object in the workpiece display accordingly. The side where you want the bar to touch the object must be on the left:

Ilustration 28: The inlay in the workpiece display: On the left rotated correctly, on the right rotated incorrectly

This cap also has surfaces which are not equally suitable for bars. In the following illustration the bar is placed at a suitable, slightly convex surface:

IMPORTANT

HINT

ENU

Illustration 29: STL mode of a cap: Suitable surface for a bar

However, a different, concave surface is less suitable for bars:

Illustration 30: STL model of a cap: Less suitable surface for a bar

Regard the quality of the surfaces for all objects and all jobs!

10.5.2 Additional information for milling jobs

In addition to information given above, regard the information in the following table when placing bars in blanks. Only then can jobs be executed achieving high quality results and without damaging the tools.

IMPORTANT

Correct 

Incorrect 

Description Place bars evenly on all sides

If you place bars on only one side, vibrations during job executions may occur. This can lead to the workpiece or tool getting damaged. Positive example (left): bars on all sides of the object. Negative example (right): bars on only one side of the object

Place bars with sufficient distance from each other

If the distance between bars is too low, the air nozzle may not be able to blow off chips as required, which can damage the tool. Positive example (left): bars with a suitable distance between them. Negative example (right): bars without a suitable distance between them.

Set enough bars

Per object you should at least place three bars because otherwise vibrations may occur during job executions. This can lead to the workpiece or tool getting damaged. Positive example (left): Enough bars set. Negative example (right): Too few bars set.

10.6 Removing bars

S 1. Click on the depicted icon. S 2. Click on the bar in the workpiece display that you want to remove.

 FINOCAM removes the selected bar immediately.

10.7 Settings drops

S 1. Click on the depicted icon. S 2. Click on the spot in the workpiece display where you want to place the drop.

 FINOCAM creates the drop at the choosen position.

10.8 Removing drops

S 1. Click on the depicted icon. S 2. Click on the drop in the workpiece display that you want to remove.

 FINOCAM removes the selected drop immediately.

11 Editing empty spaces

This step is only necessary if the following two conditions apply:

• You are editing a job with previously calculated objects.

• So called “empty areas” are placed where the calculated objects used to be.

When editing a newly created job, for example, you skip this step. In this case start the job calculation directly after setting bars and drops. Read the corresponding chapter for more information ( page 45).

What are “empty spaces” in FINOCAM?

Sometimes you have only placed and machined objects in some areas of a workpiece. FINOCAM shows these areas as empty areas where you cannot place new objects. After all, the CNC machine cannot machine new objects in these areas if you use the same physical workpiece. However, perhaps you want to use a new physical workpiece for a job with already calculated objects. In this case, the empty areas shown in FINOCAM are in fact usable on the physical workpiece. Therefore, you unlock the empty areas in the application to place objects in the areas again.

Calling up the view for editing empty areas S Click on the depicted icon in the icon bar.

display. If objects overlap these areas, the application indicates this as usual.

S 2. If necessary, correct overlapping objects in the nesting view because otherwise

you cannot calculate the job ( page 35).

12 Calculating jobs

After having fully prepared a job, you start the calculation of the milling and grinding data. FINOCAM sends these data to FINOCNC, which controls the job execution in the CNC machine. Besides calculating an individual job, you can also calculate multiple jobs in succession via the workpiece archive ( page 47).

12.1 Calculating individual jobs

FINOCNC

13 Introduction

13.1 The concept of FINOCNC

FINOCNC is a control program for your CNC machine. Among other things, you use it for the following tasks:

• Receiving the calculated job data from the CAM software.

• Automatic controlling of the CNC machine for executing jobs.

• Controlling of individual machine functions (e.g. air extraction on/off)

• Milling of calibration and test specimens

• Administrating of the tool changer

• Archiving and restoring job data The functions of FINOCNC are closely linked to the used CNC machine. Depending on the machine, different functions will be available. For example, only if you use a machine with a blank changer will the corresponding options display on the user interface. Therefore the illustrations in these instructions for use may not always reflect the state of your software installation. In this case, missing options are not caused by a software error. For grinding jobs you need a suitable CNC machine. You may also need the optional wet grinding option. When we describe grinding jobs in these instructions for use, we assume that you use the required equipment. If you do not process grinding jobs, ignore the corresponding information.

13.2 Intended use

 Only use the application on a fully PC compatible device under a supported

operating system ( page 8).  Always use the newest version of FINOCNC that is released for your CNC

machine and operating system. You receive the newest ver- sion from customer

support or via the internal update function of FINOCNC.  Use FINOCNC

only

in the

User mode

. Only participating in a special training at

FINO GmbH entitles the user to run the application in the

Administrator mode

. All other uses are not intended. FINO GmbH cannot be held reliable for damage resulting from misuse!

14 The user interface

You control FINOCNC almost completely through one application window. Only for some functions does an own window open.

 Note the general information about the user interface which applies to FINOCAM

as well as FINOCNC ( page 5).

The icon bar in FINOCNC

In order to use the many functions of the application in only one window, you open different views through an icon bar in the header of the application window. Every view contains control elements for one specific section.

 Through the icon bar you also call up the settings section. This section has an

additional icon bar below the standard icon bar ( page 51).

IMPORTANT

The following illustration shows the icon bar in the application window of FINOCNC:

Activating cleaning reminder S In order to receive one message per day which reminds you to clean the CNC

machine, activate the Cleaning reminder check field.

Specifying the source of job data

To execute jobs, FINOCNC needs job data previously calculated by a CAM application. You can import these job data in two ways:

• If you use FINOCAM: FINOCNC automatically imports new jobs from a fixed folder and offers them for execution.

• Via an icon in the job execution view, which you use to manually add job data created by a different application than FINOCAM.

You can use both import options alongside each other.

S 1. If you want the depicted icon for the manual import of CAM data to display in the

job execution view, activate the Import icon for external CAM data check field.

S 2. If you use FINOCAM: To specify the folder for the automatic import, click on the

depicted icon and choose the desired folder in the window that opens.

Specifying the duration of job data storage S Specify through the Number of days of data storage drop-down list for how long

the data of already executed jobs will be stored. As long as jobs are stored, you can restore them via the log to execute them again ( page 86).

After the specifyied time period FINOCNC deletes the data automatically. The jobs will still be listed in the job log, however, you will no longer be able to restore them.

Specifying the USB port number

FINOCNC communicates with the CNC machine through an USB connection. For a successful connection the right port must be set. You can try to automatically detect the right port via FINOCNC S To automatically detect the port, click on the depicted icon.  If the application is able to detect the port number, it enters the number into the

Port number input field. If FINOCNC does not detect the port number, you have to enter it manually. You enter the port number as follows:

S 1. Open the control panel:

• Windows 7 and Windows Vista: In the start menu click on Control panel.

• Windows 8: Press <WINDOWS KEY + I> and then click on Control panel in the Settings side panel.

 The control panel opens. S 2. Double-click on the Device manager entry.

 The Device manager window opens. S 3. In the tree view open the node Ports (COM&LPT)

 The node contains an entry USB Serial Port (COM<x>).

<x> stands for the required port number.

S 4. In FINOCNC enter the port number in the Port number input field. S 5. Close the device manager and the control panel.

Marking the blank position

If the CNC machine marks blanks at their border with one or two holes, re-inserting them in the same position is made easier for you.

S To turn on this function, activate the Mark blank position check field.

Activating air extraction when the front cover is opened

When cleaning the working chamber of your CNC machine, it is recommended to activate the air extraction. Therefore you can specify that the air extraction is automatically turned on when you open the front cover.

S To turn on this function, activate the Activate the air extraction when

opening the front cover check field.

15.2.3 Specifying the tool life

In the Tool availability CAM software view you specify the tool life for each tool type. The tool life is the maximum number of operating hours that the tools can be used before it is worn. FINOCNC stores the remaining operating hours for each tool type separately: The application subtracts the time in use automatically when the tool is used during job execution and updates the remaining tool time accordingly. This way you always keep track of the life of your tools which allows you to replace tools in time. In addition to the decimal value FINOCNC displays the tool life as a value bar. The green portion stands for the remaining time, and the red portion stands for the time that the tool has already been used.

Illustration 37: Value bar for displaying the tool life On the left: New tool On the right: Tool after multiple operation hours

To make sure that FINOCNC knows the maximum life of each tool, you specify it as follows:

 The Tool availability CAM software view is being displayed. ( page 55). S 1. In the h column enter the maximum tool life for the corresponding tool type.

Format: Decimal value in hours (e. g. 12,0 for 12 hours).

S 2. Press <ENTER>.

15.2.4 Activating the press down function for tools

When the spindle of your CNC machine puts a tool into the tool changer, it may not push the tool into the position completely. For this reason, you can specify for each tool type that after putting the corresponding tool into the tool changer the spindle presses the tool into the position again. This makes sure that the tool is pushed in completely. This function increases the tool change time only marginally, however, it decreases the risk of an incompletely pushed in tool significantly. Therefore we recommend turning on this function for every tool type. You activate this function for individual tool types as follows:

 The Tool availability CAM software view is being displayed ( page 55). S Activate the check fields in the Press down column for the desired tool types.

15.2.5 Configuring the manual tool change

By default, the CNC machine uses the built-in tool changer to change the tools during job execution. In some cases such as the following, this may not be desired for specific tool changer positions:

• A position in the tool changer is worn so that it can no longer properly hold any tools.

• You use a tool which does not fit into the tool changer.

For these cases you specify in the machine geometry view that the machine performs a manual tool change for the corresponding positions.

IMPORTANT

 You have called up the settings section.

S 1. Click on the depicted icon in the lower icon bar.

 The machine geometry view displays.

In the Positions of tools section on the right hand side, you find a list of all tool changer positions of your CNC machine.

16.3 Editing tool magazines

A tool magazine in FINOCNC represents a set of tools in the tool changer of your CNC machine. In the tool administration view you specify up to 3 magazines which you can quickly select while preparing the job execution. On the basis of the tool magazines the application knows where to move the spindle e. g. to change the tools. Therefore you have to specify at least one tool magazine before job execution. There are 3 magazines available with the following names:

• Mix

• Zirconium oxide

• Plastics

It is your choice if you select the tools according to the magazine names or if you use your own classification schema. However, you cannot change the magazine names in the application.

Selecting tool magazines

In the right area of the view [C] you find the currently selected tool magazine. Its depiction corresponds to the tool changer in your CNC machine. The individual tool changer positions are numbered accordingly. If a tool is assigned to a certain position, FINOCNC shows the corresponding tool card. Otherwise you see a grey area.
