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 of 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 manufacturer must enter the machine

geometry in machine parameters or in kinematics 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 when

disengaging from the coupling.

Before positioning with M91 or M92: 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 position display.
