2nd meas. point 2nd axis Q266 (absolute):
Coordinate of the second touch point in the minor
axis of the working plane. Input range -99999.9999
to 99999.9999
Measuring axis Q272: Axis in which the
measurement is to be made:
1
: Principal axis = measuring axis
2
: Secondary 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
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
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
Traversing to clearance height Q301: definition
of how the touch probe is to move between the
measuring points:
0
: Move at measuring height between measuring
points
1
: Move at clearance height between measuring
points
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
log
file TCHPR420.TXT
as standard in the directory
TNC:\.
2
: Interrupt program run and output measuring log
to the TNC screen. Resume program run with NC
Start.
