MEASURE PLANE (Cycle 431, DIN/
ISO: G431, software option 17)

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, the TNC positions the touch
probe at rapid traverse (value from FMAX column) (see
"Executing touch probe cycles", page 304) to the programmed
touch point
1
and measures the first 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
value 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
value of the third touch point of the plane.
4 Finally the TNC returns the touch probe to the clearance
height and saves the measured angle values in the following Q
parameters:
