 Traverse direction 1 Q267: Direction in which the
touch 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 MP6140. Input range 0 to 99999.9999;
alternatively PREDEF
 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; alternatively PREDEF
 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
Alternative: PREDEF
 Measuring log Q281: Definition of whether the TNC is
to create a measuring log:
0: No measuring log
1: Create measuring log: By default, the TNC saves
the log file TCHPR420.TXT in the directory in which
your measuring program is stored.
2: Interrupt program run and display the measuring
log on the screen. Resume program run with NC
Start.
