Compensating the machine kinematics in ACTUAL/
NOMINAL positions at end of block: M144 (Option 9)
Standard behavior
If the kinematics change, e.g. by inserting an adapter spindle or
entering an inclination angle, the control will not compensate this
modification. If the operator does not consider this modification to
the kinematics for the NC program, machining will occur with an
offset.
Behavior with M144
Refer to your machine manual.
The machine geometry must be specified by the machine
tool builder in the kinematics description.
The M144 function enables the control to consider the modification
to the machine kinematics in the position display and compensate
the offset of the tool tip in relation to the workpiece.
Programming and operating notes:
Positioning blocks with M91 or M92 are permitted
while M144 is active.
The position display in the Program Run Full
Sequence and Program Run Single Block operating
modes does not change until the tilting axes have
reached their final position.
Effect
M144 becomes effective at the start of the block. M144 does not
work in connection with M128 or the Tilt Working Plane function.
You can cancel M144 by programming M145.
