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, the TNC positions the touch
probe at rapid traverse (value from FMAX column) (see
"Executing touch probe cycles", page 294) to touch point 1.
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
1
point 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.
Parameter number
Q160

Please note while programming:

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