Touch Probe Cycles: Automatic Workpiece Inspection | REFERENCE PLANE (Cycle 0, DIN/ISO: G55)
16.2 REFERENCE 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 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!
The TNC moves the touch probe in a 3–D movement at rapid
traverse to the pre-positioning point programmed in the cycle.
There is a danger of collision according to the previous position
of the tool.
Pre-position in order to avoid a collision when the
programmed pre-positioning point is approached

Cycle parameters

Parameter number for result?: Enter the number
of the Q parameter to which you want to assign
the coordinate. Input range 0 to 1999
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
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
To conclude the input, press the ENT key.
