HEIDENHAIN TNC 430 PA/M - Contouring Behavior; Radial Acceleration

6 – 152 HEIDENHAIN Technical Manual TNC 426, TNC 430
6.10 Contouring Behavior
6.10.1 Radial Acceleration
You can define the radial acceleration of axes in addition to the simple
acceleration (MP1060):
7
77
7 Define the radial acceleration in MP1070.
MP1070 limits the feed rate during circular movement according to the
formula:
v = feed rate during circular movement [m/s]
r = radius [m] (of the path of the tool center)
HEIDENHAIN recommends:
If the programmed feed rate is less than that calculated above, then the
programmed feed rate becomes effective.
MP1070 functions for operation with both following error and feedforward
control.
