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
1
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
2
and measures the actual 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
3
and measures the actual value
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:
