 1st measuring point in 1st axis Q263 (absolute):
coordinate of the first touch point in the reference
axis of the working plane.
 1st measuring point in 2nd axis Q264 (absolute):
coordinate of the first touch point in the minor axis of
the working plane.
 1st measuring point in 3rd axis Q294 (absolute):
coordinate of the first touch point in the touch probe
axis.
 2nd measuring point in 1st axis Q265 (absolute):
coordinate of the second touch point in the reference
axis of the working plane
 2nd measuring point in 2nd axis Q266 (absolute):
coordinate of the second touch point in the minor axis
of the working plane
 2nd measuring point in 3rd axis Q295 (absolute):
coordinate of the second touch point in the touch
probe axis.
 3rd measuring point in 1st axis Q296 (absolute):
coordinate of the third touch point in the reference
axis of the working plane.
 3rd measuring point in 2nd axis Q297 (absolute):
coordinate of the third touch point in the minor axis of
the working plane.
 3rd measuring point in 3rd axis Q298 (absolute):
coordinate of the third touch point in the touch probe
axis.
 Setup clearance Q320 (incremental): Additional
distance between measuring point and ball tip. Q320
is added to MP6140.
 Clearance height Q260 (absolute): Coordinate in the
touch probe axis at which no collision between tool
and workpiece (fixtures) can occur.
 Measuring log Q281: Definition of whether the TNC is
to create a measuring log:
0: No measuring log
1: Generate measuring log: with the standard setting
the TNC saves the log file TCHPR431.TXT in the
directory in which your measuring program is also
stored.
2: Interrupt the program run and display the
measuring log on the screen. Resume program run
with NC Start.
