HEIDENHAIN iTNC 530 367
10.4 Miscellaneous Functions for Contouring Behavior
Feed rate in millimeters per spindle revolution:
M136
Standard behavior
The TNC moves the tool at the programmed feed rate F in mm/min.
Behavior with M136
With M136, the TNC does not move the tool in mm/min, but rather at
the programmed feed rate F in millimeters per spindle revolution. If
you change the spindle speed by using the spindle override, the TNC
changes the feed rate accordingly.
Effect
M136 becomes effective at the start of block.
You can cancel M136 by programming M137.
In inch-programs, M136 is not permitted in combination
with the new alternate feed rate FU.
The spindle is not permitted to be controlled when M136
is active.
