(Software Option 2)
Function
TCPM FUNCTION is an improvement on the M128 function, with which
you can define the behavior of the TNC when positioning the rotary
axes. In contrast to M128, with TCPM FUNCTION you can define the mode
of action of various functions:
„ Mode of action of the programmed feed rate: F TCP / F CONT
„ Interpretation if the rotary axis coordinates programmed in the NC
program: AXIS POS / AXIS SPAT
„ Type of interpolation between start and target position:
PATHCTRL AXIS
/ PATHCTRL VECTOR

The machine geometry must be entered in machine
parameters or in kinematic tables.
For tilted axes with Hirth coupling:
Only change the position of the tilted axis after retracting
the tool. Otherwise you might damage the contour.
Before positioning with M91 or M92 and before a TOOL CALL:
Reset TCPM FUNCTION
To avoid contour gouging you must use only spherical
cutters with TCPM FUNCTION.
The tool length must refer to the spherical center of the
tool tip.
If TCPM FUNCTION is active, the TNC shows the symbol
in the status display.
