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 work-pieces. 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. Further-more, 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 work-pieces. 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:

– 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 pro-vided in the measuring table.

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.


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.

Probe

Probe elements

Probe elements may have various forms. Examples of probe elements:

1 Sphere2 Cylinder3 Cone4 Disc

Application of the probe elements

Sphere The sphere is the standard probe element suitable for most measuring jobs.

Cylinder Cylinders are preferably used for probing thin sheet-metal parts and narrow workpiece edges.

Cone Cones are required for two applications: For ...

– self-centering probing

1 2 3 4



– High-precision probing of specified positions.

Disc A disc is used for probing deep grooves and large holes. For large holes, a disc offers the advantage of shorter travel paths as compared with the sphere.

Principles for assembly

There are two ways to assemble a probe:

– Screwing technique

– Clamping technique

Preference should be given to the screwing technique.

Probes may be assembled individually. Probe kits with different com-ponents are available.

Important!The limiting values for probes must be observed when assembling probes.

!


Probe

Screwing technique

The probe components have threads. In this way the components can be screwed together. Depending on the probe system, different thread sizes are used: M2, M3 and M5.

– M5: VAST

Probe kits

There are different probe kits, e.g. for small and large workpieces, for each probe system.

Technical data of probe components

The probe components differ with regard to material and geometry, e.g. length and diameter of the probe element. The probe weight var-ies accordingly.

The following table shows the technical data of some available probes. This data shows the influence of the material and the geo-metric sizes (e.g. length of the probe) on the probe weight. A table with the technical data of other probe components is included with the probe kits.

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 and disad-vantages of the clamp-ing technique

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 ele-ments.

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:

The probe rack is mounted by ZEISS service engineers during the ini-tial start-up. If the probe rack is to be installed in another location or a second probe rack is to be installed, you have to observe certain points.

Prerequisites for the probe rack

What are the requirements for the probe rack?

The requirements must be known before installing a probe rack.

– When using probes with long horizontal styli, it may prove impossi-ble to use all holders.

Possibly two probe racks

The requirements of the measuring job influence the number of num-ber of holders which can be used and the height of the probe rack. It may be necessary to install two probe racks.

Clarify questions in advance

The following questions must be clarified before installing the probe rack:

– Number of holders used for the measurement?

Space required by the widest probe?

– Number of probes required for workpiece measurement?

How to install the probe rack

The profile rail is attached to the guideway side. Two threaded holes are provided for this purpose. Threaded bolts are then screwed into the threaded holes and secured with a lock nut ➤“Installing a probe rack” on page 5-12.

Installation procedure

The holders are preassembled on the profile rail. The profile rail can be attached directly to the guideway side.

Important!Exact probe rack alignment is necessary to enable trouble-free probe change. The deviation must not exceed 0.1mm over the total length of the profile rail.

Start-up

Clamping the workpiece on the measuring table

Safety measures

Danger!You are exposed to the danger area of the CMM when working on the measuring table. Certain safety measures have to be observed to avoid injuries.

• Switch off the drives to prevent unintentional travel movements.

• Activate the "crane interlock“ when using lifting equipment to place the workpiece on the measuring table.

For more information see ➤ Operating instructions for the measur-ing software.

Danger!There must not be any grease film on the measuring table. Work-pieces may slide and fall off of the measuring table, thus endangering personnel. Make sure that the measuring table is free of lubricants before placing a workpiece on top of it.

• Remove any greasy or oily substances from the measuring table.

Important!The workpieces must have full contact with the measuring table. Any hard particles lying underneath the workpiece may lead to inaccurate measurements. Furthermore, the surface of the measuring table and the workpiece may be damaged.

• Clean the measuring table before placing a workpiece on the mea-suring table.

!

!

!


Clamping the workpiece on the measuring table

Important!Certain safety measures have to be observed to avoid damage to the CMM and the measuring table.

• Observe the permissible workpiece weight ➤ page 3-2.

• Lower the workpiece onto the measuring table carefully. Lower heavy workpieces at a maximum speed of 2mm/s.

The CMM may be damaged if the workpiece is set down hard.

• Make sure that the workpiece or lifting device does not strike the bridge, quill, or drive side of the CMM.

Even light jolts may affect the functioning of the CMM.

• Place the workpiece upright on the measuring table.

• Do not slide the workpiece on the measuring table.

The surface of the table could be scratched when sliding the work-piece, thus impairing the measuring accuracy of the CMM.

Clamping the workpiece

Important!The maximum permissible torque for the threaded holes in the mea-suring table is 40Nm.

• Tighten the screws to a maximum torque of 40Nm.

Workpieces made of soft materials may be deformed by chucks, thus falsifying the results of the measurement.

• If necessary, use special chucks to avoid deforming of the work-pieces.

Chucks

Chucks are screwed onto the measuring table using the threaded (M12) holes.

Metal, plastic, wood Chucks are generally made of metallic materials. Chucks made of plastic or wood may also be used if necessary.

Workpiece positioning

Position the workpiece so that all required measurements can be car-ried out without changing the workpiece position.

!

!

NOTE


Start-up

Measuring operation without collision

When using a probe rack, position the workpiece and probe rack so that measurements and probe change can be carried out without col-lision.

• Arrange the workpiece and probe rack so that no collisions can occur during the measuring run.

For more information on installing a probe rack,, please refer to .

Lowering the workpiece onto the measuring table

Workpieces can be lowered onto the measuring table either manually or by means of a lifting equipment.

Crane lock Activate the "crane interlock“ when using lifting equipment to lower workpieces onto the measuring table. The crane lock is an option. This option requires additional hardware and software. For more information, please refer to the operating instructions for the measur-ing software.

Heavy workpieces

Heavy workpieces have a hard impact if lowered into the measuring table too quickly.

• Lower heavy workpieces at a maximum speed of 2mm/s.

Elastic supports • First place the workpiece on elastic supports.

• Then replace the elastic elements with rigid supports.

Metal blocks clamped by clamping devices can be used as rigid sup-ports. Screw fasteners can be used alternatively. These fasteners can be screwed into the threaded holes in the measuring table.

NOTE


Switching the CMM on


Safety measures

Danger!A visual check must be carried out before switching the CMM on. The CMM may be switched on only if it is in perfect condition.

• Make sure that the CMM is in perfect condition ➤“Visual check” on page 5-14.

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

– 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 dan-ger 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.

NOTE


Start-up

Checking the protective circuit

The CMM is equipped with a protective circuit which monitors drive-forces 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.

!


Checking the protective circuit

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

• Try to stop the travel motion (vx) by pressing one hand against 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.

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.

Check by a ZEISS service engineer

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 protec-tive 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.

Reactivating the drives If you can stop the travel motions, you must reactivate the drives ➤ Operational controls.

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 assem-bling the probe. The limiting values depend on the probe system.

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

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

• Only use probe elements with an M5 thread.

• 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 nec-essary.

Probe extensions may be used as counterweights.

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 your-self, provided that you observe the permissible limiting values.

• Use only components that are in perfect condition.

Requirements for probe components:

NOTE

– 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.

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 ele-ments.

• 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 soft-ware.

Inserting the probe

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

Operating instructions for the measuring soft-ware

• Please read the corresponding chapters in the operating instruc-tions 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.

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 sig-naled 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 receptacle2 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.


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.

Measuring operation

What you should know!

Coordinate systems

There are three coordinate axes corresponding to the travel move-ments: x, y and z. Together these axes form a machine coordinate sys-tem. Two additional coordinate systems are required for exact calculation: the workpiece and control coordinate systems. The coor-dinate axes are assigned the letters G, W and S to identify of the coor-dinate systems:

– Machine coordinate system; xG, yG, zG

– Workpiece coordinate system; xW, yW, zW

– Control coordinate system; xS, yS, zS

For more information on the coordinate systems, please refer to the ➤ operating instructions for the measuring software.

Probing directions

Six (=6) probing direc-tions

Workpieces can be probed from six directions, ±x, ±y, ±z. The illustra-tion below shows five probing directions. The rectangular block shown cannot be probed in the positive z direction. However, in case the block has lateral recesses and bores, it is possible to probe in the positive z direction by using a corresponding probe configuration.

Probing oblique work-piece surfaces

It is also possible to probe oblique surfaces perpendicular to the prob-ing surface. This is done by means of the measuring software. The workpiece coordinate system is aligned corresponding to the work-piece surface ➤ Operating instructions for the measuring software.

Clamp the workpiece on the measuring table before probing. Other-wise, the workpiece may be shifted by the probing. Correct measure-ment is not possible if the workpiece is shifted.

Types of measurement

Overview

VAST probe system

Three types of workpiece measurements are possible with the VAST probe system:

– Single point probing

– Multipoint measurement

– Scanning

Dimensions, positions and form

Information can be obtained on the size and position. Furthermore, the workpiece form can be determined by a combination of scanning and special software.

Single point probing

Single point probing means that only one point is probed. Then the probe moves away from the workpiece. This procedure must be repeated if additional points are to be probed.

Self-centering probing, e.g. grooves, small bores, is a special single point probing application.

Complete measurement Single point probing makes it possible to measure a workpiece com-pletely. All dimensions of the workpiece are calculated by means of the probed single points. No information can be obtained regarding form. For this, scanning and a special software are required.

NOTE


Measuring operation

Probing with VAST

The probe must be moved back counter to the probing direction after each single point probing.

Measurement in static status

The measuring data are not accepted immediately after probing. Instead, they are initially polled following a damping period of approx. one second. I.e. the actual measurement occurs only after the machine reaches a static state.

Multipoint measurement

Multipoint measurement is only possible with the VAST probe system. During multipoint measurement, the probe is moved perpendicular to the probing direction.

The probing axis runs parallel to the workpiece surface. During mea-surement, the probe element constantly remains in contact with the workpiece surface. The measuring force remains effective until prob-ing is completed.

There are two options for transferring mea-sured values.

You can influence the transfer of measured values individually. The measured value can be transferred either dynamically or statically.

– Dynamic transfer of measured values:

The measured value is immediately transferred by pressing the push-button of the right joystick. The probe movement is not stopped.

– Static transfer of measured values:

Each time the CMM stops traveling a measured value is created, but not transferred immediately. Measurement transfer occurs fol-lowing a damping period of approx. one second.

Terminating the multi-point measurement

To terminate the measurement, deflect the joystick counter to the probing direction.

Scanning

Scanning is only possible with VAST probe system. During scanning, the surface of a workpiece is continuously probed. The measuring points make it possible to calculate surfaces or provide information on the form of a surface.

No axis clamping The axes of the probe head are generally not clamped during scan-ning. I.e. measurement takes place with freely movable axes.

The measuring software offers several scanning modes:

VAST circle scanning: for measuring shafts and bores whereby the CMM automatically differentiates between inside and outside bores.

VAST surface scanning: for measuring surface-like workpiece areas.

VAST line scanning: for flatness measurements or acquisition of curved shapes in predefined section planes. In this case, it is advisable to clamp one axis.

Different measuring routines are available for each scanning mode:

Four VAST stages – VAST stage 1: exact acquisition of dimensions, position and form.

Scanning with maximum precision for measuring dimensions, form and position.

– VAST stage 2: rapid acquisition of dimensions, position and form.

Scanning with high dynamic for measuring dimensions, form and position (2xV2).

– VAST stage 3: exact acquisition of dimensions and position.

Scanning with maximum precision for measuring dimensions and position.

– VAST stage 4: rapid acquisition of the position.

Scanning with maximum dynamics for measuring the position.


Measuring operation

For further information, please refer to the ➤ Operating instructions for the measuring software.

Collision protection

All probe systems provide complete collision protection for the probe head and probe in the setup mode.

After collision

If the quill, probe head or probe collides with an obstacle and the drives are switched off, proceed as follows:

• Eliminate the cause of the collision.

• Reactivate the drives on the control cabinet.

• Turn the rotary switch clockwise approx. 90° and hold it in this position until the indicator lamp above lights up.

Initializing the CMM If the drives cannot be switched on, the CMM has to be reinitialized. For more information on the initialization procedure, please refer to the ➤ Operating instructions for the measuring software.

If the quill or the probe head collides with an obstacle, the guideway and other components of the CMM may be damaged. In this case, perfect measuring operation cannot guaranteed.

• If measurements are not possible after a collision, call a ZEISS ser-vice engineer or our hotline.

After a collision, the probe must be recalibrated and the workpiece position (w position) must be determined again.

Axis clamping with VAST probe system

With the VAST probe system, axes can be clamped or unclamped. Clamping or unclamping can be carried out via the measuring soft-ware and the control console.

Probe system Protection

VAST probe system – Complete protection of the probe head and adapter plate

– Complete protection of the stylus in the setup mode

NOTE

NOTE



It is possible to unclamp one, two or all three axes.

Important!In general, the measurement has to be carried out with the same axis clamping as for calibration ➤“Probe calibration” on page 7-16.

Example: In case of unclamped axes, probing should be carried out using a probe stylus. This stylus must be calibrated in the same way. I.e.: All axes must be unclamped during the calibration of the stylus.

All axes unclamped

Vector probing Vector probing means that all three axes are freely movable. This mode is generally set in the basic setting of the measuring software.

Vector probing ensures optimum probing results for most measuring jobs. In the ideal case, the measuring force acts vertically on the sur-face being probed. Furthermore, exact correction of probe bending is ensured.

1 Freely movable axis2 Measuring force perpendicular to workpiece3 Workpiece

To prevent any misunderstandings: The workpiece is not probed in two directions. Probing always takes place in one direction: x, y or z. The probing direction depends on the alignment of the workpiece coordinate system.

Clamped axes

You can cause the measuring force to act in a certain axis by clamping specified axes.

Two axes are clamped when probing single points. The probe can be moved in the axis of the probing direction.

NOTE


Measuring operation

Self-centering probing

If the probe can be moved freely in all axes, it will be centered auto-matically, e.g. a conical probe in a bore. A combination of one clamped and two unclamped axes is also possible.

All axes are unclamped via the measuring software. Axis clamping must be carried out by means of the control console.

Measuring force

With self-centering probing it may be advisable to increase the mea-suring force or to specify the direction in which the measuring force is to act. The direction is specified by clamping the axes in which prob-ing should not take place.

Measuring software or control console

The measuring software makes it possible to alter the value of the measuring force and to specify the direction in which the measuring force is to act. The direction of the measuring force can also be set via the control console.

Temperature-sensing probe

Notes on temperature measurement

– The temperature measurement should be carried out on thick-walled workpieces.

– The workpiece surface must be clean and flat.

– The surface to be probed should be larger than the contact surface of the temperature sensor.

– Measuring force: 1N.

– The workpiece should be probed in the axis direction of the tem-perature-sensing probe.

The max. angle between the axis direction and the normals of the workpiece surface must no exceed ±5°. Perfect measuring opera-tion cannot be guaranteed with larger angles.

Operating mode

The CMM allows measuring in two operating modes: manual and automatic.

MAN operating mode In the manual mode the workpiece is probed by means of the joy-sticks. The joysticks are located on the control console ➤ operating instructions for the control console.

Possibility Comment

Temperature com-pensation

When using the temperature-sensing probe for temperature compensation, the measuring time after positioning the temperature-sensing probe is approximately five seconds. During this time, measured values are continuously transferred, evaluated and saved.

Inclusion of the temperature-sens-ing probe in a CNC program

If the temperature-sensing probe is to be included in a measuring run, the position of the temperature sensor must be known before-hand.

• Determine the position of the temperature-sensing probe.

Temperature moni-toring

It is possible to define limiting values for the temperature. Furthermore, it is possible to define when the temperature measurement is to be carried out.There are two possibilities if the limiting value is exceeded: A warning appears in the record or the CNC program is cancelled.

Temperature check The ambient air temperature can be measured at any time. The temperature is compared with the limiting valuess.There are two possibilities when the limiting values is exceeded: A warning appears in the record or the CNC program is cancelled.

Temperature recording

If the data from the last temperature measure-ment is required, the temperatures of the workpiece and the air can be recorded.

NOTE


Measuring operation

AUTO operating mode In the automatic mode the workpiece is measured by means of a CNC program. The measuring software enables programming of CNC runs.

Important!Before starting the CNC program in the AUTO operating mode, you should test the program in the MAN operating mode. The test is a safety measure to ensure that the measurement can be carried out without collision.

Selecting the operating mode

Select the operating mode on the control cabinet ➤ Operating ele-ments on the control cabinet.

Measuring software

In addition to the control console, the CMM is also operated by means of the measuring software. There are different measuring soft-ware versions for the UNIX and Windows NT operating systems. The operation of the measuring software versions varies.

• Please read the corresponding chapters in the operating instruc-tions for the measuring software before carrying out the working steps.

Standard measuring software

UNIX UMESS is the standard measuring software for the UNIX operating system. There are numerous options for UMESS, e.g. UX1 - Extended result display.

Furthermore, measuring software options are available for special measuring tasks, e.g. KUM, SAM, GON.

Windows NT Calypso is the standard measuring software for the Windows NT operating system. Provacs and Holos, for example, are used for special measuring tasks.

Safety instructions

Safety instructions

Danger!There is a risk of injuries during all movements of the CMM.

• Ensure that nobody is at risk during manual operation of the machine.

• Keep a safe distance away from to the CMM during automatic measuring runs.

Danger!The CMM is provided with a protective circuit which monitors the driving forces during movements of the bridge in the x and y axes. If a collision occurs, the protective circuit causes the drives to be cut out.

The function of the protective circuit must be checked regularly in order to guarantee the safety of the CMM.

• Check the function of the protective circuit every month ➤ page 6-8.

Important!Radio signals may interfere with operation of the CMM.

• Therefore, do not use any mobile phones or walkie-talkies within a 3m radius of the CMM.

Important!For calibration, the same measuring force and clamping of the axes must be set as later for workpiece measurement.

• Perform the calibration in the same way as you intend to probe the workpiece later on, i.e. with the same measuring force and axis clamping.

Measuring operation

Preparations for a measuring run

Prerequisites for a perfect measuring run

The following preparations have to be made to ensure maximum accuracy of the CMM.

• Switch on the CMM at least 15 minutes before starting the mea-suring run.

The CMM must be adapted to room temperature prior to the mea-suring run.

• Always carry out a reference measurement after the reference point travel and calibrate each probe used for measurement.

• Carry our temperature compensation ➤ page 7-22.

Reference point travel

Reference point

The reference point or origin is located in the upper right-hand corner of the measuring volume. It must be determined by a reference point travel prior to the measuring run ➤“Carrying out a reference point travel” on page 7-16.

Measuring operation

Carrying out a reference point travel

Danger!The reference point travel is carried out automatically. Before starting the reference point travel, make sure that nobody is at risk.

• Ensure that nobody is endangered by the travel motions.

Important!The reference point travel is carried out automatically. The probe head first moves in the z direction until it reaches the mechanical end posi-tion and then in the x and y direction.

Make sure that the reference point travel can be carried out without any collision with components on the measuring table.

• Move the probe head to a position from where the reference point travel can be carried out automatically.

Start by the measuring software

The reference point travel is started by the measuring software.

• Read the corresponding chapter in the ➤ operating instructions for the measuring software.

Safety position after reference point travel

After the reference point travel, the probe head moves to the safety position (only with UMESS). The coordinates of this position are defined in the measuring software. The coordinates must be within the measuring volume.

Example for safety position: x= 30, y= -30, z= -30.

The position of the calibration standard has to be determined after every reference point travel. Furthermore, all probes have to be cali-brated and the storage positions in a probe rack have to be deter-mined again.

Probe calibration

The measuring software is required for the following procedure.


!

!

NOTE

NOTE




Why is calibration necessary?

The computer automatically recognizes the probe system, and there-fore knows the axial center point of the adapter plate receptacle. But it does not know the length of the individual probes. The calculation of the geometric data of a workpiece is not possible without this data. Calibration is required to determine the length of the probes.

The reference measurement has to be carried out before determining the length of the probes ➤“Carrying out a reference measurement” on page 7-19.

In which cases is calibration necessary?

Calibration is necessary in the following cases:

– after a reference point travel

– after a collision

– when inserting a new stylus into the probe.

Normally, it is sufficient to calibrate the new stylus. However, you should also recalibrate all other styli of the probe. This is advisable, since the position of the other styli may have been slightly changed when the new stylus has attached.

What should be observed during calibration?

Observe the following during calibration:

– Carry out a reference measurement.

– Select the stylus to be calibrated.

– Same axis clamping as for the measuring run.

VAST probe system – With VAST probe system same measuring force for calibration and measuring run.

Calibration can be carried out manually or semi-automatically. How-ever, preference should be given to semi-automatic calibration.

Preparation

What is required for calibration?

The following is required for calibration:

– Calibration standard

A calibration standard with a highly accurate ceramic sphere is usually used ➤“Calibration standard” on page 2-12.

NOTE


Measuring operation

– Master probe

The master probe must be used for the reference measurement ➤“Carrying out a reference measurement” on page 7-19.

– Probes used for workpiece measurement.

Prerequisites for perfect calibration

Before you start calibrating, make sure that the following prerequi-sites are met:

– The probe is stable.

– All probe components are screwed together firmly.

– The limiting values for the probe design are observed.

– The calibration sphere, probe elements and adapter plate are clean and not damaged.

– Probe components are not damaged.

Mounting the calibration standard on the measuring table

Since the calibration standard has a magnetic base, it must be placed on a metal plate so that the magnet can act. A metal plate must therefore be screwed onto the measuring table.

1 Rotary lever for activating the magnet2 Metal plate with through holes3 M12 threaded hole in the measuring table4 Example of position of metal plate (for mounting calibration standard).



• Screw the metal plate on the measuring table (max. torque 40Nm).

Select the metal plate position so that probing of the probe sphere is possible with all probes.

• Place the calibration standard on the metal plate and turn the rotary lever 90° to position I in order to activate the magnet.

The calibration standard can be placed in any position on the metal plate.

Carrying out a reference measurement

The position of the calibration standard must be calibrated prior to the length of the styli. Use the master probe for this purpose. Proceed as follows:

1 Insert the master probe in the adapter plate receptacle ➤ page 6-16.

2 Call the menu for reference measurement ➤ Operating instruc-tions for the measuring software.

3 Select probe (stylus) 1 on the control panel.

• Press the button between the five LEDs until the LED for probe 1 lights up.

4 Probe the sphere of the calibration standard to determine the diameter of the sphere.

5 Remove the master probe from the adapter plate receptacle ➤“Removing the probe (manually)” on page 6-17.

Now, you can calibrate all probes.

Calibration procedure

After the reference measurement has been carried out, the probes can be calibrated.

Semi-automatic calibration should be carried out for all probe sys-tems.

Tensor calibration should be carried out for the VAST measuring probe system. This is important since the measuring force causes a

Measuring operation

certain bending of the probe. Tensor calibration makes it possible to correct the bending for subsequent probings.

Tensor calibration must be carried out by means of vectors. The probe can be moved in all axes.

1 Insert the probe into the adapter plate receptacle ➤ page 6-16.

2 Open the menu for calibration ➤ operating instructions for the measuring software.

3 Select the clamping status of the axes, i.e. clamped or unclamped.

The same axis clamping status must be set as will be required later on for workpiece measurement to prevent measuring errors.

Axis clamping must be performed via the control panel.

4 Probe system specific actions:

• The measuring force must be set for the VAST probe system.

5 Select the stylus to be calibrated on the control panel.

6 Call the menu for calibration in the measuring software and probe the calibration sphere ➤ Operating instructions for the measuring software.

The calibration sphere diameter is output as the result.

7 Check the result.

Standard deviation The result is evaluated based on the standard deviation. There is no maximum standard deviation which applies to all applications. The tolerable deviation depends on many factors: e.g. resolution and precision of the CMM, length and rigidity of the probe shaft, qual-ity of the probe tip, cleanness of the environment. Normally, the standard deviation should be within a range of a few micrometers (e.g. 0.002).

If the result is not satisfactory, repeat the calibration or look for plausible causes. It might be necessary to decide whether or not to accept measuring inaccuracies.

8 Repeat points 2 to 6 for all other styli of the probe.

3

2

4

5



9 Calibrate further probes if necessary.

In this case, repeat items 1 to 7.

If high precision is required or in case of high temperature fluctua-tions, the calibration procedure should be repeated regularly.

If the CMM is in operation for several weeks without interruption and the same probes are always required for measurement, the probes should be calibrated every week.

Causes of large deviations

If large deviations occur during calibration, measuring inaccuracies may also be expected during subsequent measuring runs. In order to avoid such inaccuracies, the mechanical design of the corresponding probe should be checked.

Sources of faults and errors

The sources of faults and errors which may lead to increased devia-tions are listed in the following.

Probe design – Probe design is not stable.

– Probe components are not screwed together firmly enough.

– The permissible probe limiting values were not observed.

The probe is too long, too heavy or contains components which are not suitable.

Probe status – The calibration sphere or probe element is soiled, oiled-up or dam-aged.

– Probe components or the adapter plate are/is damaged.

Magnetic field – A fault was caused by a magnetic field.

Possible causes of a magnetic field: e.g. workpiece, clamping tool, probe extensions.

Influence of tempera-ture

– The probe is inserted manually and calibrated immediately.

The temperature of the probe material as well as the material properties change as a result of hand heat.

Even minor differences in temperature influence the material prop-erties. The degree of this effect depends on the probe compo-nents.

Measuring operation

Temperature compensation

What is temperature compensation?

The measuring software calculates the workpiece geometry for the material properties at 20°C. 20°C is the reference temperature. Since the actual temperature deviates from 20°C, the geometric data have to be corrected by a correction value.

Expansion coefficient The correction value is calculated by the measuring software. How-ever, the measuring software needs to know the temperature of the CMM and the workpiece. Furthermore, the expansion coefficient must be entered in the measuring software ➤ operating instructions for the measuring software.

Procedure:

• Enter the expansion coefficient for the workpiece material in the measuring software.

• Connect the temperature sensors ➤ page 7-22.

Calculating the correc-tion value

The measured values are automatically transferred to the measuring software. The measuring software calculates the correction value.

All of the geometric data measured on the workpiece are corrected by the correction value with respect to the reference temperature of 20°C. Exact workpiece measurement is thus guaranteed.

Connecting the temperature sensors

Two temperature sensors are included in the standard equipment of the CMM. These sensors are required for temperature compensation.

Sensor components The temperature sensors consist of a copper block, a long cable and a connector.

1 Copper block2 Connector

• Plug the connector into the connecting sockets.

The connecting sockets are located on the rear side of the CMM. Two sockets are available.

1 Two connecting sockets; rear side of the CMM

Application of the sen-sors

• Place the copper blocks at two different locations in or on the workpiece to be measured.

When should temperature compensation be carried out?

Temperature compensation can be carried out continuously. In some cases it is imperative to carry out temperature compensation:

– Carry out temperature compensation each time you measure a new workpiece.

Temperature compensation values can be integrated in the CNC workpiece measurement program.

Measuring operation

Probing the workpiece

How to ensure correct measurement

Important!Regular inspection of the probes is required to ensure correct work-piece measurement.

• Check the styli, the probe components and the adapter plate regu-larly.

• Remove any particles or grease film from the probe elements and the adapter plate.

• Replace any damaged styli.

Probing procedure

Selecting the type of probing

The type of probing depends on the measuring job and the required number of measuring points. Position measurement requires only one or several single point probings. Multipoint probing or scanning can be used to measure surfaces. Scanning must be used for form mea-surements.

Probing sequence

Probing conditions

For probing, certain conditions must be fulfilled. The conditions depend on the probe system. The following conditions must be ful-filled:

– Constant probing speed.

Working step Example

1 Select the probe stylus.

2 For scanning with VAST:Select the scanning mode and start the measuring rou-tine.

Circle, surface, cylinder …

4 Probe the workpiece.



– Minimum distance from the contact point.

A minimum distance is required to reach the probing speed. The minimum distance is 0.5mm.

Probing speed

Probing should be carried out at constant speed.

The speed depends on the deflection range of the joystick. At the beginning and end of the deflection range, the speed is proportional to the deflection range. The speed between the beginning and the end is constant. This speed corresponds to the probing speed.

Probing speed depen-dent on the deflection range of the joystick

v Speedv1 Probing speed;optimum speed during probing.

Maximum possible speed

The maximum possible speed is reached at full deflection range of the joystick. In the setup mode, the max. speed is approx. 70mm/s. The actual speed depends on the standard value defined in the measuring software and the position of the control knob on the control panel.

Proceed as follows:

1 Enter a standard value of 100% in the measuring software.

2 Adjust the speed using the control knob on the control panel.

If the control knob is turned clockwise as far as possible, the maxi-mum possible speed corresponds to the standard value, e.g. 100%, defined in the measuring software.

The control knob allows to reduce the speed to zero. If the speed reaches a value of less than 10% of the standard value, this will be indicated on the control panel. An LED on the standard control panel lights up.

• If the speed is too high for certain probings, reduce the maxi-mum possible speed.

Turn the control knob counterclockwise to reduce the speed.

When probing oblique workpiece surfaces with an angle between 30° and 50°, the probing speed has to be reduced.

NOTE


Measuring operation

Aligning the probe

It is still possible to align the probe after it has been assembled. This may be necessary if some points on the workpiece cannot be probed.

The alignment of the probe for the VAST probe system is described in the following.

1 Screws in the adapter plate for VAST

• Loosen the three screws in the adapter plate so that the probe configuration can be turned. Do not completely unscrew the screws!

• Insert the probe in the adapter plate receptacle.

• Turn the probe configuration until the required position is reached.

• Hold the probe configuration and remove the probe from the adapter plate receptacle.

• Tighten the screws with a torque of 2Nm.

Preventing measuring errors

Measuring errors may have several causes. Answer the following questions before starting the measurement:

1

Questions regarding the prevention of measuring errors

yes / no

– Are the probing surfaces of the workpiece clean?

– Is the workpiece secured against shifting?

– Are the probe assembly criteria fulfilled?

– Are the probe and the stylus in perfect condition?



If you answered all of the above questions with "yes“, measuring errors can be excluded to a large extent.

Special features of VAST probe system

Setting the measuring force

The measuring force has to be set for measuring probe systems such as VAST. The value of the measuring force must be entered in the measuring software ➤ operating instructions for the measuring soft-ware.

The measuring force must be set prior to calibrating the probe. Set the measuring force for each probe individually if required.

Why does the measur-ing force have to be set?

During probing, the probe element causes changes of the workpiece form. The extent of these form changes influences the precision of the calculated values. In order to avoid falsified measuring data, the measuring force should be adapted to the characteristics of the work-piece material.

– Has the reference point travel been carried out?

– Has the reference measurement been carried out?

– Has the calibration been carried out correctly?

– Has tensor calibration for the VAST probe system been carried out?

– Have all probe styli been calibrated?

– Has the correct probe stylus been selected?

– Has the same axis clamping as for calibration been selected?

– Has the same measuring force as for calibration been selected? – Only for VAST probe system.

– Has temperature compensation been carried out?

Questions regarding the prevention of measuring errors

yes / no

NOTE


Measuring operation

Example: Greater changes in form can be expected with soft work-piece materials and high measuring force than with hard workpiece materials and low measuring force. In this case, the measured value is falsified by the extent of the form change.

A Nominal status: no workpiece deformation.B Falsified measurement due to indentation of the workpiece. Reason: soft

material and high measuring force.1 Extent of falsification

0,2N – normal The measuring force can be set continuously. Normally, a measuring force of 0.2N has to be used for measurement. If larger form changes are to be expected, the measuring force should be 0.1N.

• Set the measuring force according to your requirements.

With self-centering probings a higher measuring force in the MAN operating mode might be useful in order to improve centering ➤“Self-centering probing” on page 7-8.

• Increase the measuring force if necessary.

Precision positioning during probing

With the VAST probe system, the joysticks are temporarily deactivated immediately after the probe contacts the workpiece. The CMM con-trol takes over the precision positioning of the probe. The measured value is accepted.

NOTE



Notes on scanning

High travel speed

Important!When measuring at high travel speed and with low measuring forces (F< 0.1N), the probe may lift off the workpiece for a short time. In unfavorable cases, this may lead to incorrect measured values.

• Reduce the travel speed in case of low measuring forces.

Abrasion or material deposits

During scanning, the probe contacts the workpiece continuously. The probe element glides along the surface of the workpiece. This may cause abrasion and material deposits.

– Abrasion:

Material may be rubbed off the workpiece or probe element (e.g. in case of sintered material) by the probe as it glides along the sur-face of the workpiece during probing.

– Material deposits:

With certain materials (such as aluminum) material may be removed from the workpiece and deposited on the probe element.

For this reason, probe elements should be checked regularly during all scanning operations and replaced if necessary.

• Check the condition of the probe elements and clean them.

For information on how to remove aluminum deposits, please refer to ➤ page 9-6.

• If the probe element is damaged, replace the stylus.

!

NOTE


Measuring operation

Automatic probe change

A probe rack is required for automatic probe change. Preparations have to be made prior to an automatic probe change.

• Allocate a storage position (holder).

A specific storage position in the probe rack must be allocated to each probe. You should note which storage position is allocated to which probe.

• Make sure that there is no collision during the probe change.

It is possible to define intermediate positions. This is done in order to determine the path along which the probe moves to the storage position.

The measuring software is required in order to carry out this proce-dure.


NOTE


Tips for effective operation

Tips for effective operation

Changing the probe automatically

If several probes are required for workpiece measurement, you should note which probe you have assigned to which storage position.

If you require more probes than can be accommodated by the probe rack, it is possible to mount several probe racks on the measuring table.

Do not switch off the CMM if ...!

The start-up procedure involves a number of worksteps which take a while to perform. Furthermore, the CMM should be switched on 15 minutes before carrying out the first measurement. You can save time by leaving the CMM switched on.

The CMM should not be switched off in the following cases:

– If it is operated during multiple shifts.

– If workpiece measurement takes several days and the CMM should measure under constant conditions.


Measuring operation

Evaluating the measuring data

Limiting values for deviations

Standard deviation The result is evaluated based on the standard deviation. There is no maximum standard deviation which applies to all applications. The tolerable deviation depends on many factors: e.g. resolution and pre-cision of the CMM, length and rigidity of the probe shaft, quality of the probe tip, cleanness of the environment. Normally, the standard deviation should be within the range of a few micrometers (e.g. 0.002 [mm]).

It might be necessary to decide whether or not to accept measuring inaccuracies.

Causes of large deviations

The sources of error which may lead to increased deviations are listed in the following.

Source of error Cause

Reference point – No reference point travel has been carried out.

– No reference measurement has been carried out.

Calibration – Different axis clamping than for calibration

– Different measuring force than for calibration (with VAST)

Temperature compensation – Temperature compensation has not been carried out.

– Incorrect temperature compensation.

Probe design – Probe design is not stable.

– Probe components are not screwed together firmly enough.

– Permissible probe limiting values have not been observed.

The probe is too long, too heavy or contains components which are not suitable.

Probe status – Calibration sphere or probe element is soiled, oiled-up or dam-aged.

– Probe components or adapter plate are/is damaged.

Magnetic field – A fault was caused by a magnetic field.

Possible causes of a magnetic field: e.g. workpiece, clamping tool, probe extensions.

Probing – Probing was not carried out perpendicular to the probing surface.


Terminating a measuring run

Terminating a measuring run

Effect of system shutdown

If you put the CMM out of operation and switch it off completely, the following data will be lost.

– Reference point

– Information on the coordinate systems.

When putting the machine into operation again, you must perform another reference point travel.

Shutdown procedure

After the CMM is put out of operation, the probe head remains in its last position. The space coordinates of its position are lost.

In order to avoid faults when the CMM is put back into operation, the measuring run should be terminated correctly. For information on the operator‘s controls, please refer to ➤ page 2-8.

• Proceed as follows:

CMM 1 Move the probe head to a safe position.

This position must be inside of the measuring volume. Prepare for the next start-up by positioning the probe head close to the refer-ence point.

Computer 2 Terminate the measuring software.

3 Power down the operating system.

4 Switch off the computer.

Maintenance and care

Maintenance

Purpose of mainte-nance work

Proper maintenance ensures …

– safe measuring operation,

– that there are no downtimes,

– that the CMM always measures with maximum accuracy.

In order to guarantee these features in the long run, the CMM requires regular maintenance.

Danger!Maintenance work must be carried out only by skilled personnel. These persons must have received special training on the correspond-ing CMM qualifying them to carry out all necessary maintenance work.

Maintenance agree-ments

We recommend concluding a maintenance agreement to guarantee safe operation. ZEISS offers maintenance agreements which relieve you of any need to worry about maintenance.

• If you would like to subsequently conclude a maintenance agree-ment retrospectively, call our hotline.

The phone number of our hotline is: +49 (0)180/3336337.

Regarding maintenance work, a distinction is made between maintenance and machine care.

Maintenance:

– Preventive maintenance is performed on all components according to the work plans.

– Inspection of precision, adjustment and calibration.

– Replacement of wearing parts.

Machine care:

– Preventive maintenance is performed on defined components according to the working plans.

– Verification and correction of geometry and calibration.

– Replacement of wearing parts.

Maintenance intervals The time intervals between two maintenance calls depend on the degree of utilization. Generally, maintenance should be carried out at at least every 2000 operating hours.

!


Maintenance

We recommend:

Scope of maintenance work

Maintenance work includes inspection of the following:

When concluding a maintenance agreement, you also must specify any optional equipment to be covered.

Degree of utilization Scope of annual maintenance work

1-shift operation: 1 x maintenance

2-shift operation 1×maintenance + 1×machine care

3-shift operation 2×maintenance

Components Examples

Safety devices (standard equipment)

For example drive monitoring; colli-sion protection in the Series measure-ment mode

Compressed-air supply For example air bearings, pressure controller, air filters, valves

Measuring system For example functioning, precision

Control For example operator’s controls on the control cabinet; control panel

NOTE



Care

Although the CMM is robust and easy to care for, a certain degree of care is still required. The sensitive measuring system of the CMM requires a certain degree of cleanliness. Even the smallest dust parti-cles on the probe element or the calibration sphere may cause inaccu-rate measurements.

Cleaning and checking Measures for care also include the regular cleaning and checking of certain components.

For cleaning, you require:

– Mild detergent

– A fluff-free cloth, e.g. made of linen

– A vacuum cleaner

– If necessary, special solvent for removing aluminum deposits from the probe element, e.g. KOH (10%).

Danger!When carrying out care measures, make sure that no travel move-ments are performed.

• Switch off the drives on the control cabinet in order to enable safe execution of the care measures.

Important!

• Do not use compressed air for cleaning.

Use fat dissolving and non-corroding cleaning agents. We recom-mend Clean from JVA. This cleaning agent can be ordered from us – order no.: 84865.

Preventive care also includes making sure that all workpieces to be measured are clean. The workpieces must be free from machining res-idues (e.g. metal chips, oil) and dust.

• Clean the workpieces before placing them on the measuring table.

Before placing a workpiece on the measuring table make sure that the measuring table is clean.

• Remove larger particles with a vacuum cleaner.

• Then clean the measuring table with a mild cleaning agent.

Danger!There must not be any grease film on the measuring table. Work-pieces may slide and fall off the measuring table, thus presenting a risk to the personnel. Before placing a workpiece on the measuring table make sure that the measuring table is free from lubricants.

• Remove any greasy and oily substances from the measuring table.

Threaded holes

Dust may accumulate in the threaded holes and threads. In order to ensure perfect condition of the threads, remove any dirt deposit from the threaded holes with a vacuum cleaner.

Probe elementsProbe elements may be soiled e.g. by dust particles. Furthermore, material from the workpiece being probed may settle on the probe element, especially during scanning.

• Clean the probe elements with a fluff-free cloth.

• Use a cleaning agent if required.

Make sure that the probe element is free from cleaning agent resi-dues.

The styli must be handled carefully. If force is exerted, the glued bond between the probe element and the probe shank may be separated and the probe shank may be bent or broken.

• Do not exert any force when cleaning.

If material from the workpiece settles on the probe element, it can be removed with special solvents.

Removing aluminum deposits

An aluminum deposit can be removed with 10% NaOH solvent (soda lye) or with 10% KOH solvent (potassium lye). Make sure that the sol-vents do not act too long since the glued bond between the probe element and the probe shank may be affected. For cleaning, proceed as follows:

• Wear rubber gloves and safety glasses.

• Immerse a cloth (e.g. cotton cloth) into one of the two solvents and clean the probe element with the cloth.

!

NOTE


Care

• Rinse the probe elements immediately with water and dry them.

Danger!Caustic solvents may represent a health hazard. When using caustic solvents, always take protective measures, e.g. wear rubber gloves and safety eyeglasses.

• Observe the general protective measures when handling harmful solvents.

Whenever the styli are not in use, store them in a safe place, ideally in the probe kit.

Calibration sphere

The calibration sphere must be clean and in perfect condition to ensure correct calibration.

• Clean the calibration sphere with a fluff-free cloth.

• Use a cleaning agent if required.

Make sure that the probe element is free from cleaning agent resi-dues.

Adapter plate

The adapter plate must be protected against soiling.

• Store the adapter plate in a dust-free and clean place, e.g. in a cabinet or drawer, whenever it is not in use.

Cleaning:

Wipe off the adapter plate with a dry or damp cloth. Dry the adapter plate in order to avoid oxidation of its contacts.

If the adapter plate is dirty:

• Clean it with a mild cleaning agent.

• Then dry it.

Make sure that the adapter plate is free from cleaning agent residues. The function of the adapter plate could otherwise be adversely affected.

Probe head

The adapter plate and the adapter plate receptacle must be protected against soiling.

• Put a protective cap on the adapter plate receptacle of the probe head whenever no probe is inserted in the adapter plate receptacle or the probe head is not in use.

!hss

NOTE



• Store the probe head in a dust-free and clean place, e.g. in a cabi-net or drawer.

Cleaning:

Clean the probe head with a dry or damp cloth.

If the adapter plate receptacle is dirty:

• Clean the adapter plate receptacle with a mild cleaning agent.

• Then dry the adapter plate receptacle.

Make sure that the adapter plate receptacle is free from residues of the cleaning agent. The function of the adapter plate receptacle may be affected.

Probe rack

Vacuum the probe rack and the storage positions with a vacuum cleaner and clean them with a mild cleaning agent.

• Remove all cleaning agent residues.

Concertina cover

Vacuum the concertina cover with a vacuum cleaner and clean it with a damp cloth.

Important!The cover must not be removed.

Housing covers

Vacuum the housing covers and clean them with a damp cloth.

Important!The housing covers must not be removed.

Inspection measures

Checking the probe

Intensive care of the CMM also includes inspection of the compo-nents used.

Regular inspection of the probes is required to ensure correct work-piece measurement.

• Check the styli, other probe components and the adapter plate regularly.

!

!


Care

• Remove any particles or grease film from the probe elements and the adapter plate.

• Replace any damaged styli.

Abrasion or material deposits

During scanning, the probe contacts the workpiece continuously. The probe element glides along the surface of the workpiece. This may cause abrasion and material deposits.

– Abrasion:

Material may be rubbed off the workpiece or probe element (e.g. in case of sintered material) by the probe as it glides along the sur-face of the workpiece during probing.

– Material deposits:

With certain materials (such as aluminum) material may be removed from the workpiece and deposited on the probe element.

For this reason, probe elements should be checked regularly during all scanning operations and replaced if necessary.

• Check the condition of the probe elements and clean them.

For information on how to remove aluminum deposits, please refer to ➤ page 9-6.

• Replace the stylus if the probe element is damaged.

Cleaning/changing the filter mat

The interior of the control cabinet is cooled by a fan. The fan is attached to the rear side of the control cabinet. The filter mat in the intake hole must be cleaned every three months.
