Measure Plane - HEIDENHAIN ITNC 530 - CYCLE PROGRAMMING User Manual

16.13 MEASURE PLANE (Cycle 431,
DIN/ISO: G431)
Cycle run
Touch Probe Cycle 431 finds the angle of a plane by measuring three
points. It saves the measured values in system parameters.
1 Following the positioning logic (see "Executing touch probe
cycles" on page 318), the TNC positions the touch probe at rapid
traverse (value from MP6150) to the programmed starting point
and measures the first touch point of the plane. The TNC offsets
the touch probe by the safety clearance in the direction opposite
to the direction of probing.
2 The touch probe returns to the clearance height and then moves in
the working plane to starting point
of the second touch point of the plane.
3 The touch probe returns to the clearance height and then moves in
the working plane to starting point
of the third touch point.
4 Finally the TNC returns the touch probe to the clearance height and
saves the measured angle values in the following Q parameters:
Parameter number Meaning
Q158 Projection angle of the A axis
Q159 Projection angle of the B axis
Q170 Spatial angle A
Q171 Spatial angle B
Q172 Spatial angle C
Q173 to Q175 Measured values in the touch probe axis
