16.4 MEASURE ANGLE (Cycle 420,
DIN/ISO: G420)
Cycle run
Touch Probe Cycle 420 measures the angle that any straight surface
on the workpiece describes with respect to the reference axis of the
working plane.
1 Following the positioning logic (see “Executing touch probe
cycles” on page 318), the TNC positions the touch probe to the
programmed probe starting point 1 at rapid traverse (value from
MP6150). The TNC offsets the touch probe by the safety clearance
in the direction opposite the defined traverse direction.
2 Then the touch probe moves to the entered measuring height and
probes the first touch point at the probing feed rate (MP6120).
3 Then the touch probe moves to the next starting position 2 and
probes the second position.
4 The TNC returns the touch probe to the clearance height and saves
the measured angle in the following Q parameter:

Parameter number Meaning
Q150 The measured angle is referenced to the
reference axis of the machining plane.
Before a cycle definition you must have programmed a
tool call to define the touch probe axis.
If touch probe axis = measuring axis, set Q263 equal to
Q265 if the angle about the A axis is to be measured; set
Q263 not equal to Q265 if the angle is to be measured about
the B axis.
