Precision Positioning During Probing - Zeiss CenterMax Operating Instructions Manual

Measuring operation
0,2N – normal
NOTE
7-28
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
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
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.
