The FUNCTION TCPM function allows you to influence the positioning behavior of the control. When activating FUNCTION TCPM, the control compensates for any changed tool angles of inclination by means of compensating movements of the linear axes.
FUNCTION TCPM allows, for example, changing the tool angle of inclination for inclined machining while the position of the tool location point relative to the contour remains the same.
Instead of M128, HEIDENHAIN recommends using the more powerful function FUNCTION TCPM.
