Touch Probe Cycles: Automatic Workpiece Inspection
15.2 DATUM PLANE (Cycle 0, DIN/ISO: G55)
15.2
DATUM 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!
Pre-position the touch probe 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.
