HEIDENHAIN iTNC 530 HSCI - Display of the M Functions; Feed Rate for Rotary Axes

July 2013 8.1 Display and operation 1157
Feed rate for
rotary axes
The iTNC interprets the programmed feed rate for a rotary axis in degrees per
minute. The contour feed rate depends on the distance of the tool center from
the center of the rotary axis.
With the M116 function the contouring feed rate can be converted to mm/min.
In this way the feed rate is independent of the distance from the tool center
to the center of axis rotation:
 Define the rotation center of the rotary axis with MP75xx. Also see page
701.
