16.2 REF. PLANE (Cycle 0,
DIN/ISO: G55)
Cycle run
1 The touch probe moves at rapid traverse (value from FMAX
column) to the starting position
2 Then the touch probe runs the probing process at the probing feed
rate (column F). 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:
Danger of collision!
Pre-position the touch probe in order to avoid a collision
when the programmed pre-positioning point is
approached.
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.
