Introduction

Proper use

Warranty

The coordinate measuring machine (CMM) may be used only for its intended purpose. The user is liable for any damage incurred during improper use of the CMM.

CMM

The CMM can be used to determine the geometric sizes of workpieces. The workpieces may be made of metal or plastic.

Movable axes The CMM can be moved in all axes and probes the workpiece in the x,

y and z coordinate directions. A rotary axis is available when using a rotary table.

Dimensions, position and form

Geometric sizes are for example width, length, height as well as the diameter and depth of bores.

The position of bores is calculated from the measuring data. Furthermore, the form of workpieces, e.g. the form of a turbine bucket can be determined by means of a special software.

Danger!

The CMM must not be used for determining geometric sizes of workpieces. The CMM must not be used for any purposes other than those listed below.

Only workpieces and objects required for measurement may be placed on the measuring table.

Functions of the CMM:

– Workpiece probing in six directions (±x, ±y, ±z).

This is ensured by means of three moving machine axes. Probing is executed by a probing system. For measurement, the workpieces must be fastened on the measuring table.

– The measuring table has the following functions:

1-6

– Support of one or more workpieces

– Support of the calibration tools

– Storage of a probe rack (option)

– Storage of a rotary table (option) – the rotary table is either inte-

grated in the measuring table or attached on top of it.

– Fastening of the workpieces and installation of the probe racks,

calibration tools and the rotary table via the threaded holes provided in the measuring table.

61211-1020202 CenterMax Operating Instructions

Proper use

Improper use

The CMM must not be used for purposes other than the proper use.

Examples for use contrary to the proper use:

– The machine axes must not be used to move objects.

– The z axis of the CMM must not be used to lift objects.

– The CMM must not be used to measure living objects or parts of

the body.

Probe system

The probe system is a hightech product which may only be used only for its intended purpose.

Probing CMM probe systems are designed to determine the coordinates of a

workpiece. This is usually achieved via a probing, during which the workpiece is probed by a probe element (stylus tip). In some cases optical measuring techniques are used.

Linear scales The probe system comprises several components, such as the probe

head and linear scales. The linear scales are integrated in the machine axes of the CMM and protected by covers. These covers must be attached when the CMM is in operation to prevent it from being used improperly.

Probe

The probe consists of several components: adapter plate, probe styli and probe joints. A probe may be equipped with one or more styli.

The probe element is located at the end of the stylus.

Functions of the probe:

– The adapter plate holds and positions the probe exactly in the

probe head.

– Workpiece probing is carried out by the probe element.

Probe head

The probe head is inserted in the quill. The probe used for probing is inserted below the probe head. Handle the probe head and probe very carefully.

Functions of the probe head:

– Holding the probe.

– Exact positioning of the probe.

1-7CenterMax Operating Instructions61211-1020202

Introduction

– Detection of probe deflection and transmission of the signal to the

computer. The computer calculates the coordinates of the probed point.

Improper use

The probe head and probe must not be used for purposes other than the proper use.

Examples:

– The probe head must not be used as a support.

– The probe must not be used as lever arm, e.g. to loosen a ring bolt.

– The probe must not be used as striking tool.

Clamping technique

Laterally oriented styli are inserted in grooved discs and clamped by the vertically oriented stylus. The end stylus is screwed into the probe extension or directly into the adapter plate. In this way the laterally oriented styli are clamped.

The probe components for the clamping technique and assembly instructions are included in the probe kit.

Advantages:

– high flexibility

– low weight.

Disadvantages:

– high measuring inaccuracy caused by poorly definable clamping

joints.

– with VAST: loss of rigidity at each joint.

Storage of probes

Once the probe has been assembled, it can be used as long as required. It does not need to be disassembled. Careful handling is necessary. This applies particularly to the adapter plate and probe elements.

Probe protection The probe must be protected against the following influences:

– Force of impact and other external mechanical infuences

– Dust and dirt.

A probe rack is recommended for storage if you measure every day with the CMM. When no measurements are carried out with the CMM over a longer period, the probes should be stored in a place protected against environmental influences:

Switching the CMM on

Switching the drives on

• Turn the rotary switch (4) clockwise approx. 90° and hold it there until the indicator lamp above it lights up.

As soon as the indicator lamp above the switch lights up, the drives are switched on. The rotary switch does not engage. snaps back to its home position as soon as it is released.

Selecting the operating mode

It is also possible to set the operating mode later.

• Turn the key-operated switch (6) to the required position.

MAN: Manual mode – Set-up mode. The travel speed is limited in

all three axes. You must set this operating mode for …:

– Joystick-controlled probing

NOTE

– Programming CNC runs

– Testing CNC programs.

AUTO: Automatic mode – series measurement mode. Travel at

maximum speed in all axes. You must set this operating mode for …:

– Workpiece measurement by means of a CNC program.

Danger!

When starting a CNC program, make sure that no one is in the danger area of the CMM. The operating mode setting (MAN or AUTO) is irrelevant.

• Check to make sure that no one is in the danger area of the CMM.

Important!

The AUTO mode may only be set if the CNC program was tested in the manual mode beforehand. This prevents collisions at high travel speeds in the automatic mode.

When starting a CNC program, the key should be removed and stored in a safe place to prevent the setting from being changed accidentally.

Switching the computer on

• Switch the computer on and other peripheral devices, e.g. the printer.

• Boot the computer; start the operating system.

• Start the measuring software.

Start-up

Checking the protective circuit

The CMM is equipped with a protective circuit which monitors driveforces during bridge positioning movements in the x and y axes. The shearing force monitoring is effective in all operating modes.

Function of the protective circuit

Drives must cut out automatically.

If the traveling motion is obstructed by a collision in the x or y axis and the shearing force therefore exceeds a value of approx. 150N, the drives must cut off automatically.

Danger!

In order to ensure the safety of the CMM during measurement, the function of the protective circuit must be checked regularly.

• Check the protective circuit on a monthly basis.

Check

When performing the check, you must proceed as follows:

x axis

• Move the crossbeam forward just far enough so that you can grasp the quill housing with one hand.

6-8

61211-1020202 CenterMax Operating Instructions

Checking the protective circuit

• Move the probe (head) in the x axis at constant speed.

• Try to stop the travel motion (v

the quill housing at the marked position (F).

This increases the shearing force of the drives. Once the shearing force has exceeded a certain value, all drives will be deactivated.

vx: Speed of quill in x axis

F: Force exerted against the quill housing by pressing it with one hand.

) by pressing one hand against

Check by a ZEISS service engineer

Reactivating the drives If you can stop the travel motions, you must reactivate the drives

Important!

You may press only against the quill housing.

• Do not press against the quill or against the probe head. The probe head and quill could otherwise be damaged.

Under normal circumstances, the force of your hand should suffice to stop probe movement. If the movement can not be stopped in this way, the protective circuit must be checked immediately by a ZEISS service engineer.

• Call your service engineer and arrange for him to check the protective circuit.

Danger!

If the protective circuit is not functioning properly, the CMM must be taken out of operation until the protective circuit has been checked by a ZEISS service engineer.

• Move the control panel to the drive side for y-axis travel. The drive side is located on the right side of the CMM.

vy: Quill speed in y axis

F: Force which must be exerted manually against the crossbeam on the drive side.

• Perform crossbeam travel in the y axis at constant speed.

• While the crossbeam is traveling, try to stop its movement by

pressing against the crossbeam with one hand.

Important!

You may press against the crossbeam only on the drive side.

Probe assembly

Screwing technique or clamping technique?

Although the probe can be assembled by clamping its parts together, it is preferable to use the screwing technique.

Advantages of screwing technique:

– Easy assembly

– Complex probe configurations possible

– Stable design.

The following example describes how to assemble probes using the screwing technique.

For further information please refer to the chapter ➤“Storage of probes” on page 2-24.

Safety measures

Important!

Probes must not be assembled on the probe head. The probe head could thus be damaged.

• Do not attach any probe elements to the probe while it is inserted in the adapter plate receptacle.

Important!

Assemble the probe configuration carefully. Do not exert any force when screwing the components together.

• Screw the components together manually. Assemble them fully.

• Use the pin included in the probe kit to tighten the components.

Important!

Observe the limiting values regarding weight and length when assembling the probe. The limiting values depend on the probe system.

6-12

• Observe the limiting values ➤“Limiting values” on page 6-14.

61211-1020202 CenterMax Operating Instructions

Probe assembly

Criteria and limiting values for assembling probes

Criteria

An unfavorable probe assembly may impair the measuring accuracy. Therefore, it is necessary to observe the following criteria for assembly.

• Only use probe elements with an M5thread.

• Stable design with as few components as possible.

• Symmetrical design with respect to weight; the center of gravity

must be located in the physical center; use counterweights if necessary.

Probe extensions may be used as counterweights.

NOTE

Check the balance by holding the adapter plate between two fingers and letting it swing back and forth until it comes to a stop. The probe must point in a vertical downward direction.

• Do not assemble probes with more than one branching.

• If possible, never use joints when assembling oblique probe config-

urations. It is preferable to use components shaped according to your corre-

sponding requirements. You can also make such components yourself, provided that you observe the permissible limiting values.

• Use only components that are in perfect condition. Requirements for probe components:

6-13CenterMax Operating Instructions61211-1020202

Start-up

– perfect condition

– clean

– grease-free

• Observe the limiting values; probe length and probe weight.

Limiting values

The maximum weight and length must not be exceeded in order to ensure error-free measurement by the probe system.

The limiting values depend on the probe system used.

Maximum values VAST

Probe weight – including adapter plate

Probe length – including extension:

600g

450mm

Example

Connecting parts are usually required to assemble the required probe configuration. It is also possible to screw the probe directly into the adapter plate ➤ page 6-15.

Inserting / removing the probe

Safety measures and information

The probe is held in place by an electromagnet or solenoid. If the measuring software initiates insertion or change of the probe, the magnetic force is reduced. The full magnetic force becomes effective after 20 seconds.

The measuring software is required for inserting and changing a probe.

• Please also read the corresponding chapters in the operating instructions for the measuring software.

Important!

Probes must not be assembled on the probe head. The probe head could be damaged.

• Insert only finished probes equipped with all necessary probe elements.

• Do not attach any probe elements to the probe as long as it is inserted in the adapter plate receptacle.

Important!

A VAST probe automatically falls off of the adapter plate receptacle after a specified period of time.

• Hold the probe immediately after activating change in order to avoid damage to the probe, the workpiece or the measuring table.

The period after which the probe falls off is set in the measuring software.

Inserting the probe

Operating instructions for the measuring software

6-16

The procedure for inserting a probe is basically the same for all probe systems. This procedure must be initiated by the measuring software.

• Please read the corresponding chapters in the operating instructions for the measuring software.

1 Initiate the procedure by means of the measuring software.

Then, insert the probe within 20 seconds. If the probe is not inserted within this time, you have to repeat this procedure.

61211-1020202 CenterMax Operating Instructions

Inserting / removing the probe

2 Insert the probe in the adapter plate receptacle.

The pin must engage in the groove ➤ drawing. The probe is attracted by the magnet. The completion of probe insertion is signaled by an audible click.

Position of the pin The pin position in the adapter plate receptacle depends on the

probe system.

VAST: pin on the left side.

1 Pin in the probe head adapter plate receptacle 2 Groove in the adapter plate.

Removing the probe (manually)

The procedure for removing a probe is basically the same for all probe systems. However, several special points must be observed. First, the procedure must be initiated by the measuring software.

• Please read the corresponding chapters in the operating instructions for the measuring software.

1 Initiate the procedure via the measuring software.

With the VAST probe system, the delay required until the probe is released from the adapter plate receptacle must be specified in the measuring software.

Set the delay so that enough time always remains to grasp the probe after initiating probe removal. This is essential to prevent damage to probes, workpieces, or the measuring table caused by falling probes.

2 Remove the probe.
