Digitizing with rotary axes
If you are using a triggering touch probe, the digitizing feature supports
rotary axes with the cycles MEANDER (Cycle 6), LINE (Cycle 8) or
CONTOUR LINE (Cycle 7). Regardless of the digitizing cycle used, the
corresponding rotary axis must be entered in the RANGE cycle. The
TNC interprets the rotary axis input as values in degrees.
If you are using a measuring touch probe, the digitizing feature
supports rotary axes with cycle 18 LINE only. The rotary axis must be
defined as a column axis.
Surface data
The digitized data contains position information on the axes that are
identified in the RANGE cycle.
The TNC does not generate a BLK FORM since rotary axes cannot be
graphically simulated.
The display mode of the rotary axis (i.e. whether the
display reduces the values to below 360° or not) must be
the same for digitizing as for milling.
