Cycle parameters

1st meas. point 1st axis Q263 (absolute):
Coordinate of the first touch point in the reference
axis of the working plane. Input range -99999.9999
to 99999.9999
1st meas. point 2nd axis Q264 (absolute):
Coordinate of the first touch point in the minor axis
of the working plane. Input range -99999.9999 to
99999.9999
Measuring height in the touch probe axis Q261
(absolute): Coordinate of the ball tip center (=
touch point) in the touch probe axis in which
the measurement is to be made. Input range
-99999.9999 to 99999.9999
Set-up clearance Q320 (incremental): Additional
distance between measuring point and ball tip.
Q320 is added to SET_UP (touch probe table). Input
range 0 to 99999.9999
Measuring axis (1 to 3: 1 = Reference axis) Q272:
Axis in which the measurement is to be made:
1: Reference axis = measuring axis
2: Minor axis = measuring axis
3: Touch probe axis = measuring axis
Traverse direction 1 Q267: Direction in which the
probe is to approach the workpiece:
-1: Negative traverse direction
+1: Positive traverse direction
Clearance height Q260 (absolute): Coordinate in
the touch probe axis at which no collision between
touch probe and workpiece (fixtures) can occur.
Input range -99999.9999 to 99999.9999
Measuring log Q281: Define whether the TNC
should create a measuring log:
0: Do not create a measuring log
1: Create a measuring log: The TNC saves the
file TCHPR427.TXT
TNC:\.
2: Interrupt program run and output measuring log
to the TNC screen. Resume program run with NC
Start.
Maximum limit of size Q288: Maximum
permissible measured value. Input range 0 to
99999.9999
Minimum limit of size Q289: Minimum permissible
measured value. Input range 0 to 99999.9999
