General Description of the PROFIL Function

1.1 General

PROFIL is a graphic module installed in the numerical control (CNC). PROFIL can be used to create contours of milled or turned workpieces, etc., using

ISO programming or PROCAM interactive programming.

1.2 Capabilities of the PROFIL Function

PROFIL allows the user to create all or part of workpiece contours made up of a sequence of geometric elements (irregular or freehand contours) or predefined shapes (rectangles, circles or polygons) then machine these contours by calling subroutines.

PROFIL also offers the possibility of:

- Immediately viewing the contour elements being created

- Modifying a contour being created or editing a contour already created

- Transforming, duplicating or deleting a contour.

It should be noted that:

- Contour creation can be carried out in background mode (during execution of a part programme)

- The contours are generated by PROFIL in ISO language

- PROFIL can be used in place of the Profil Geometry Programming (PGP) function.

en-938937/0 1 - 3

1.3 PROFIL Operating Procedures

When creating or editing a contour, the user must make choices in a page displayed on the screen.

1.3.1 Configuration of a PROFIL Screen Page

The PROFIL function uses a special screen page configuration. This page includes four windows, three of which are dedicated to PROFIL and one to the CNC.

The page displayed below is the one that appears at the beginning of creation of a new contour (see "Entering and Exiting from the PROFIL Function").

1.6 Contour Numbering

When a new contour is created, the system automatically assigns the lowest available number by default. This number can be modified immediately or after saving the contour (range from 1 to 383 maximum).

Renumbering a Contour after Saving It

You can renumber a contour after saving it when the dialogue window containing the contour identifier is displayed. This window is displayed by selecting the contour in the graphic window then selecting "Information" in the "- PROFILE -" menu.

Note on Numbering of Contour Copies

When you copy a contour by applying a geometric transformation (see Sec. 2.3), copies of the contour are created and the smallest available numbers are assigned by default.

Example: Making three copies of contour No. 3. If contour numbers 1, 3 and 4 are already assigned, numbers 2, 5 and 6 are assigned

to the three new copies.

General Description of the PROFIL Function

1.7 Calling a Contour Created by PROFIL

To be executable, a numbered contour created by PROFIL must be called. The call can be made in two different ways:

- By the subroutine call function G77

- From a G63, G64 or G65 machining cycle.

The contour call syntax differs according as the contour was created inside the main part programme or in a separate subroutine.

1.7.1 Contour Call by Function G77

General Contour Call Syntax by Function G77

G77 [H..] [N.. N..] P.. [S..]

G77 Unconditional contour call. H.. Number of the external subroutine containing the

contour. N.. N.. Number of the first and last contour block. P.. Number of the contour created by the PROFIL function. S.. Number of repetitions of the contour created.

Examples of Contour Calls

Call of a Contour Located in the Main Programme Single call of contour 1 in the main programme

1.8 Description of the Programme Generated by PROFIL

When a contour is created by PROFIL, the software converts the graphically generated contour to an entity.

CAUTION

The entity generated cannot be directly modified in ISO language. Any modification

concerning a contour must be made using the "Modification" option in the "PROFIL" menu.

2.1 Contour Types

Creating and Editing Contours

The sections below describe the capabilities offered by PROFIL for creating and modifying contours, i.e.:

- The types of contours that can be drawn by PROFIL

- The geometric elements and tools used during contour creation

- The geometric transformations that can be applied to the contours created

- The special tools available for creating contours.

The following types of contours can be created with PROFIL:

- Irregular contours

- Contours with predefined shapes (rectangle, circle, polygon). It should be noted that some of the contour creation possibilities described are

common for turning and milling and others are specific to either turning or milling.

X-Axis Value Entry in Turning Mode

Depending on the type of programming declared for a turning type machine (see parameter P4), the values on the X axis can be entered with reference to the diameter or radius.

2.1.1 Irregular Contours

Irregular or freehand contours are constructed as a sequence of geometric line or arc elements. Fillets and chamfers can be applied to the intersections between elements (see the section "Elements and Tools for Contour Creation").

Irregular contours can be open or closed. They can be modified during or after creation.

2.1.2 Contours with Predefined Shapes

Macros are provided for the following predefined contour shapes:

- Rectangle

- Circle

- Polygon. These contours are closed. Rectangular and polygonal contours can include

chamfers and fillets at the intersections of their sides. After creation, a contour can be modified to transform it into an irregular contour. The

transformation can be carried out by the function "Disengage object" (see below) for a contour that has just been created or by the "Modification" function for a contour that is stored.

2.1.2.1 Rectangle

Angle

Reference point

Definition Data

The rectangle definition data are as follows:

- Width

- Length

- Angle

- Radius.

Description of Rectangle Data

Length and Width The length is defined with respect to the X axis and the width with respect to the Y (or

Z) axis depending on the working plane selected. If the angle is 0, the rectangle length is parallel to the X axis.

Angle The rectangle can be pivoted by entering an angle (positive in the counterclockwise

direction). The rectangle is rotated around the reference point declared after confirming the definition data.

Radius When a value is entered in the "Radius" field, four equal radii are applied to the four

corners of the rectangle.

Rectangle Reference Point and Position

After confirming the dimensions, the software prompts for definition and location of the reference point. If an angle was defined, the angular rotation is referenced to this point.

Five reference points are possible:

- Bottom left corner (lower left limit)

- Bottom right corner (lower right limit)

- Top left corner (upper left limit)

- Top right corner (upper right limit)

- Centre. For instance, in the figure opposite, the

rectangle is rotated around the bottom left corner.

2.1.2.2 Circle

Creating and Editing Contours

Definition Data

A circle is defined by its diameter.

2.1.2.3 Polygon

Circle Position and Reference

After confirmation of the diameter, the circle position is defined with respect to its centre point.

Definition Data

The polygon definition data are as follows:

- Number of sides

- Side length/length across flats (entry side)/length across points (overshoot)

- Angle

- Radius.

Description of Polygon Data

Number of sides The polygon can have from 3 to a maximum of 99 sides.

Side length/length across flats/length across points Depending on its dimensions, the polygon can be defined by one of the three following

dimensional parameters:

- Side length

- Length across flats (entry side)

- Length across points (overshoot).

The required dimension, i.e. side length, length across flats or length across points, is selected by left/right arrow keys. These three parameters are interdependent (when one of them is entered, the other two are calculated automatically by the software).

Dimensioning of polygons:

Length across points

Angle

Dimensioning with an odd number Dimensioning with an even number of sides of sides

Side length

Angle The polygon can be positioned by entering an angular value (positive in the

counterclockwise direction) with respect to the reference axis. The polygon is then rotated around the centre.

Example:

- Rotation with respect to the X axis.

Radius When a value is entered in the Radius field, the polygon is assigned radii of the same

length in each angle.

Polygon Reference Position

After confirming the dimensions, the position of the polygon is defined with respect to its centre.

2.2.2 Geometric Elements for Contour Construction

The geometric elements are as follows:

- Line

- Circle.

2.2.2.1 Notes on Use of Geometric Elements

Definition of Elements and Sequences The possibilities for constructing contours using line and circle geometric elements

are described below with reference to figures and tables. The data are given for the XY plane, but can be adapted for the other working planes (ZX or YZ).

The number of solutions allowing connections between elements to be defined varies according to the configuration of the sequence. The software proposes solutions (the number of solutions per sequencing case is given in the tables below).

In all the cases of construction illustrated, the start point "D" of the element or sequence is known.

An intermediate circle is displayed in certain sequences including arcs. In the case of a CNC with colour screen, this intermediate circle is red (if the colour was not changed in the colour palette). For the definition cases covered below, the intermediate circle is shown as a thin line and the arc as a boldface line.

Reminder

When creating or modifying a contour, only the commands displayed in boldface characters can be selected.

Creating and Editing Contours

2.2.3.1 Fillet/Chamfer

You can select the Radius(Fillet)/Chamfer command to insert a fillet or chamfer between geometric elements. The fillet and chamfer are considered respectively as an arc and a line. They can only be inserted at the intersection between two elements already constructed.

The location where the fillet or chamfer is to be inserted is selected with the left/right arrow keys (to move the square onto the intersection).

A chamfer or a fillet can only be inserted between secant elements or tangent elements with change of direction.

Fillet/Chamfer Definition Data

Fillet A fillet is defined by its radius.

Chamfer The chamfer definition data are as follows:

- Width

- Length

- Width and angle.

en-938937/0 2 - 19

Page 52

Description of the Fillet

Inserted fillet

Theoretical intersection

Radius In all cases the radius specified for the fillet must always allow a tangent connection

between the elements where the fillet is inserted. A fillet can be inserted between the

following elements:

- Line/line (case 1)

- Arc/arc (case 2)

- Line/arc (case 3).

Case 1

Case 2

Point "a" is the point of intersection between the two elements where the

Case 3

fillet is to be inserted.

Notes on constructions with a fillet In certain cases of construction, it is not always possible to create an arc by the Circle

command of the menu used for creation, because the theoretical intersection between the two elements cannot be used during construction. This case of connection can be solved by inserting a fillet.

Example:

- Construction of the part of the contour (points a-b-c) as though there where no intermediate connection

- Then, insertion of the fillet in the theoretical point of intersection (b).

2 - 20 en-938937/0

Description of Chamfer Data

In all cases, the dimension assigned to the chamfer must not be greater than the length of the smallest of the lines between which the chamfer is inserted.

In certain cases, a chamfer can be inserted between two lines, one of which was already created by insertion of a chamfer.

2.2.3.3 Deletion

2 - 22 en-938937/0

The Deletion command can be selected to delete the geometric element (line or circle) selected on the contour.

The element to be deleted is selected with the arrow keys (left/right). When an intermediate geometric element was deleted during construction of a

contour, it is impossible to add interposed elements independent of the contour. It is therefore necessary to restore the interrupted sequence and reconstruct a single contour.

Deletion Possibilities

After selecting and deleting an element, the software proposes the following possibilities:

- End chaining

- Shift in X and Y direction

- Shift in X direction

- Shift in Y direction

- Continue with one of the contours

- Continue with an open contour.

Description of the Deletion Subcommands

End chaining

This command causes lengthening or shortening of the adjacent geometric elements to restore the connection between the separated parts of the contour.

Case of an open or closed contour.

Shift in X and Y direction This command defines the X and Y shift

of one of the parts of the contour to restore the connection between the separated parts.

This command applies to an open contour.

Shift in X direction Same as shift in XY direction but on X only.

Shit on Y direction Same as shift in XY direction but on Y only.

Continue with one of the contours This command is used to delete one of the parts of the contour made independent

by deletion of a geometric element. After selecting the part to be kept, the other part is deleted. A new replacement element can then be created.

This command applies to an open contour. Continue with an open contour

This command defines the end of the contour where the new element can be constructed (end selected by Change direction).

This command applies to a closed contour. Otherwise, deletion of an element causes the contour to be separated into two contours.

The Last element command displays the values entered to construct the last geometric element created in the dialogue window. These values can be modified.

The Zoom command is used to enlarge or reduce part of the contour. The Zoom command causes display of a rectangular zoom window in the graphic

window. The zoom window can be moved and the contour zone selected using the arrow keys (left/right).

Zoom Possibilities The following possibilities are available for defining a zoom:

- Reduce the window

- Enlarge the window

- Zoom on last element

- Full view.

Description of Zoom Possibilities

Reduce the window This command decreases the zoom window displayed. The size is decreased by

pressing the Reduce the window function key the number of times required.

Enlarge the window This command enlarges the zoom window displayed. The window is enlarged by

pressing the Enlarge the window function key the number of times required. The maximum enlargement is 1000 times.

Zoom on the last element This command automatically zooms on the last element of the contour.

Full view After using the zoom command, this command is used to return to the full view of the

contour in the graphic window.

2.2.3.6 Change Direction

The Change direction command is used to go from one end to the other of the contour displayed in order to change the direction of construction. This function applies only to open contours.

When a change of direction is defined in the description of the contour, this command reverses the direction during simulation.

2.2.3.7 Calculator

The Calculator command displays the calculator integrated in the software for calculating values. This function is available only when inserting the coordinates of a point on the contour.

General

The calculator performs operations on numbers with up to five digits before and three after the decimal point. The result of an operation can be rounded off by the software when there are more than three decimal digits.

Basic operations +: Addition

Determination of X intersection point and Y intersection point After you choose X intersection point or Y intersection point, the software creates an

imaginary line at the X or Y distance entered. One or more geometric elements can be intersected by this line. The point intersecting the element selected is selected with the arrow keys (left/right).

2.3 Geometric Transformation Tools

2.3.1 Possibilities of Geometric Transformations

PROFIL can be used to perform the following transformations on a contour after creation:

- Shift

- Rotation

- Mirror

- Scaling factor.

After construction, the contour must be selected and confirmed in order for the geometric transformation(s) to be applied to it.

When the data required for the transformation have been entered and confirmed, the software proposes to copy the original contour and asks for the number of copies to be made. The original contour can be kept by copying it (see Sec. 1.6 for notes on contour copy numbers).

When a contour is copied such that each end point of the original contour corresponds to the start point of the next copy, the new contour created is listed under the same number as the original contour (this case is possible for shift, rotation and mirror).

2.3.1.1 Shift

Definition Data

The contour shift definition data are as follows:

- Shifting by a value

- Shifting of a point of the contour to a specific point.

Description of Shift Data

Shifting by a value The original contour is shifted incrementally on the X and Y coordinates. Example:

- Shifting of the original contour by X20 and Y25.

Page 63

Creating and Editing Contours

90°

Shifting of a point on the contour to a given point In this case, it is necessary to define a reference point on the original contour then the

absolute coordinates of the point where it is to be shifted. Example:

- Reference point P located at X15 and Y5

- Point shifted to X35 and Y30.

Y30

2.3.1.2 Rotation

Definition Data

The contour rotation definition data are as follows:

- Rotation reference point

- Value of the angle of rotation.

Description of Rotation Data

Rotation reference point The X and Y coordinates of the reference point are entered. There are two possibilities for the position of the rotation reference point:

- Rotation point located on the contour

- Rotation point located off the contour.

Example of rotation point located on the contour:

- Reference point P at X25 and Y25 (absolute)

- Rotation by 90 degrees around point P.

Page 64

90°

2.3.1.3 Mirror

Example of rotation point located off the contour:

- Reference point P located at X25 and Y25 (absolute)

- Rotation by 90 degrees around point P.

Definition Possibilities

The mirror definition possibilities that can be applied to a contour are as follows:

- X mirroring

- Y mirroring

- X and Y mirroring.

Description of Mirror Possibilities

After selecting the type of mirroring (X, Y or XY), the mirror may be shifted on the mirroring axis (shift with respect to the reference point). If no shift is to be applied, it is necessary to enter the value 0.

X Mirroring Mirroring on the X axis is applied with

respect to an axis parallel to the Y axis.

respect to an axis parallel to the X axis. Mirroring on the X axis is applied with

respect to an axis parallel to the Y axis.

Page 66

2.3.1.4 Scaling Factor

Definition Data The data applying a scaling factor to a contour are as follows:

- Fixed point

- Scaling factor.

Description of Scaling Factor Data

Fixed point The contour is enlarged or reduced with respect to a fixed point whose X and Y

coordinates must be entered before the scaling factor. Scaling factor

When a scaling factor is applied to a contour, the original dimensions of the contour are modified.

Possibilities:

- Factor greater than 1: Contour enlarged (maximum factor 1000)

- Factor less than 1: Contour reduced (minimum factor 0.001).

Example:

- Fixed point P at X25 and Y25

- Scaling factor = 2.

2.4 Miscellaneous Tools

2.4.1 Disengage Object

The Disengage object command is mainly used to modify a contour with a predefined shape (rectangle, circle, polygon).

The Disengage object function is not available until contour creation has been confirmed (without exiting from PROFIL).

Accessing and Selecting Disengage Object

When the contour with a predefined shape that has just been created is displayed, selecting Modification causes display of the contour dimensions. The Disengage object function is available.

Creating and Editing Contours

When you select Disengage object, the "Profile" menu is displayed. You must then select Modification again.

The contour is displayed with the square marker moved on geometric elements using the arrow keys (left/right).

Possibilities of the Disengage Object Function

The following possibilities are available:

- Line

- Circle

- Geometry

- Deletion

- Zoom

- Change direction.

Description of the Disengage Object Commands

Notes on Line and Circle Two case can occur:

- The contour with a predefined shape has not been modified and is still a closed contour

- The contour with a predefined shape has been modified by deletion of one of its elements (see Deletion) and has become an open contour.

Closed contour: In this case, the start of the line or circle to be defined is the origin of the contour with the predefined shape.

Open contour: In this case, the start of the line or circle can be one of the ends of the open contour.

REMARK The other commands in this menu are used in the same way as

described above.

2.4.2 Confirming and Saving a Contour After Creation

After creating a contour and confirming it by the Confirm key, the Profile menu is displayed in the dialogue window.

Possibilities after Confirming the Contour

The following commands are available:

- Creation

- Modification

- Geometric transformations

- Deletion

- Information

- Save.

Description of Commands after Confirming

Creation The Creation command is used to create a new contour with the same programme

number without exiting from the PROFIL function. Modification

The Modification command is used to display and possibly modify a contour already created.

Geometric transformations The Geometric transformations command is used to apply geometric transformations

to the contour. Deletion

The Deletion command is used to delete the contour selected. If several contours are defined in the same programme, the contour to be deleted is

selected with the arrow keys (left/right). Information

The Information command is used to edit the instructions identifying the contour selected (Number, First Nxx, Comment).

Save The Save command is used to save the contour created. PROFIL always asks you

to confirm that you want to exit to avoid exiting involuntarily without saving the contour.

Once you confirm exit, the programme containing the contour definition is displayed (the programme generated cannot be edited).

2.4.3 Contour Choice

Creating and Editing Contours

The Contour Choice command is available only when several contours are displayed (contours created with the same programme number). You can select one of the contours to view the information concerning it or modify it, etc.

The contour is selected with the arrow keys (left/right).
