## PC-DMIS NC Rotary Tables

### Overview

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.

- The typical NC configuration of a pair of stacked rotary tables is also supported. For a machine with this configuration, one of the tables must assume a fixed position for measurement.

Rotary tables are calibrated for location and orientation by generating a program using the PC-DMIS rotary table calibrate option in the Rotary Table Setup dialog box. The calibration information is stored by machine and recalled for each program analysis or path generation.

Tips may be calibrated 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.

Note: The Rotary Table option must be programmed into the port lock 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.
