The values in the CMM Limits area of the Part/Machine tab in the Setup Options dialog box enables PC-DMIS to avoid collisions with the legs on Bridge-type CMMs during the calibration of tactile probes.
When you calibrate a tactile probe with long extensions, collisions may occur when the probe rotates in the different tip positions. To avoid collisions, you can enable the Leg Collision check. PC-DMIS runs the check online and just before the probe calibration routine. The Leg Collision check can automatically add safety movements.
When PC-DMIS connects to a supported Hexagon CMM machine (common controllers and FDC controllers), it automatically gets the CMM limits. You can manually edit the CMM limits. This can be useful if you do not have a Hexagon CMM. In addition, you might want to reduce the limits to avoid collisions with objects located within the machine volume (tool changers, fixtures, and so on).
To run the Leg Collision check, do the following:
If you need to modify or add the limits of the machine, enter the values in the X Min, Y Min, Z Min, X Max, Y Max, and Z Max boxes in the CMM Limits area.
Calibrate the probe tips. For details, refer to the "Calibrating Probe Tips" topic in the "Setting Up and Using Probes" chapter in the PC-DMIS CMM documentation.
To reset any modified values and obtain the CMM limits from your Hexagon CMM again, do the following:
Type 0 into the X Min, Y Min, Z Min, X Max, Y Max, and Z Max boxes.
Click OK to close the Setup Options dialog box.
Restart the measurement routine, or restart your machine.
