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.
1 Following the positioning logic (siehe „Executing touch probe
cycles” auf Seite 334), 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 to 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.
