Cycle run
Touch Probe Cycle 427 finds a coordinate in a selectable axis and
saves the value in a system parameter. If you define the
corresponding tolerance values in the cycle, the TNC makes a
nominal-to-actual value comparison and saves the deviation value in
system parameters.

Following the positioning logic (see "Executing touch probe cycles"
on page 332), the TNC positions the touch probe to the 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 TNC positions the touch probe to the entered touch point
1 in the working plane and measures the actual value in the
selected axis.
3 Finally the TNC returns the touch probe to the clearance height and
saves the measured coordinate in the following Q parameter:

Before a cycle definition you must have programmed a
tool call to define the touch probe axis.
