PC-DMIS NC rotary table support is based on capabilities within PC-DMIS. The following configurations are supported:
Only one continuous rotary table
Two unconnected rotary tables
Indexed rotary tables
Typical NC configuration of a pair of stacked rotary tables. For a machine with this configuration, one of the tables must assume a fixed position for measurement.
To calibrate rotary tables for location and orientation, generate a measurement routine and then click the Calibrate button on the Rotary Table Setup dialog box (Operation | Calibrate/Edit | Rotary Table). PC-DMIS stores the calibration information by machine and then recalls it for each measurement routine analysis or path generation.
You can calibrate tips either with the vendor supplied macros (such as Renishaw) or PC-DMIS probe calibration. Tip length and rotary table center position are interrelated when the tip is not parallel to the rotary table axis. This is the typical case represented by a horizontal machining center with a rotary table vector aligned with the Y axis. Consequently, changes in tip length will affect the rotary table calibrated position. Spindle growth is the prominent error for machine tools reflected in Z tip position. Any error on the horizontal configuration will be doubled between zero and 180 degrees rotary table position.
You must have the Rotary Table option enabled in your LMS license or portlock as well as at least one CNC license. To use a stacked rotary table with PC-DMIS, the Stacked Rotary Table option must be programmed as well.
