Cycle run
1 The touch probe moves at rapid traverse (value from MP6150 or
MP6361) to the starting position
1 programmed in the cycle.
2 Then the touch probe approaches the workpiece at the feed rate
assigned in MP6120 or MP6360. The probing direction is to be
defined in the cycle.
3 After the TNC has saved the position, the probe retracts to the
starting point and saves the measured coordinate in a Q
parameter. The TNC also stores the coordinates of the touch probe
position at the time of the triggering signal in the parameters Q115
to Q119. For the values in these parameters the TNC does not
account for the stylus length and radius.
Please note while programming:
Cycle parameters
U Parameter number for result: Enter the number of
the Q parameter to which you want to assign the
coordinate. Input range: 0 to 1999
U Probing axis/Probing direction: Enter the probing
axis with the axis selection keys or ASCII keyboard
and the algebraic sign for the probing direction.
Confirm your entry with the ENT key. Input range: All
NC axes
U Nominal position value: Use the axis selection keys
or the ASCII keyboard to enter all coordinates of the
nominal pre-positioning point values for the touch
probe. Input range: -99999.9999 to 99999.9999
U To conclude the input, press the ENT key.

Danger of collision!
Pre-position the touch probe in order to avoid a collision
when the programmed pre-positioning point is
approached.
