3.1 Measuring Workpiece Misalignment

1 The TNC positions the touch probe to the starting points at rapid

traverse (value from FMAX column) following the positioning logic

(see “Running touch probe cycles” on page 21) to the

programmed starting point 1. The TNC offsets the touch probe by

the safety clearance in the direction opposite the defined traverse

direction.

2 Then the touch probe moves to the entered measuring height and

probes the first touch point at the probing feed rate (column F).

3 Then the touch probe moves to the next starting position 2 and

probes the second position.

4 The TNC returns the touch probe to the clearance height and

moves the rotary axis, which was defined in the cycle, by the

measured value. Optionally you can have the display set to 0 after

alignment.

Before programming, note the following

Before a cycle definition you must have programmed a

tool call to define the touch probe axis.

Cycle 403 must not be used if the “Tilt working plane”

function is active.

The TNC stores the measured angle in parameter Q150.
