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 339) to the programmed
touch point and measures the first point of the plane. The TNC
1
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:
