 Center of 1st axis Q273 (absolute): Bolt hole circle
center (nominal value) in the reference axis of the
working plane.
 Center in 2nd axis Q274 (absolute): Bolt hole circle
center (nominal value) in the minor axis of the working
plane.
 Nominal diameter Q262: Enter the approximate bolt
hole circle diameter. The smaller the hole diameter,
the more exact the nominal diameter must be.
 Angle of 1st hole Q291 (absolute): Polar coordinate
angle of the first hole center in the working plane.
 Angle of 2nd hole Q292 (absolute): Polar coordinate
angle of the second hole center in the working plane.
 Angle of 3rd hole Q293 (absolute): Polar coordinate
angle of the third hole center in the working plane.
 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.
 Clearance height Q260 (absolute): Coordinate in the
touch probe axis at which no collision between tool
and workpiece (fixtures) can occur.
 Datum number in table Q305: Enter the number in the
datum or preset table in which the TNC is to save the
coordinates of the bolt-hole circle center. If you enter
Q305=0, the TNC automatically sets the display so
that the new datum is on the bolt hole center.
 New datum for reference axis Q331 (absolute):
Coordinate in the reference axis at which the TNC
should set the bolt-hole center.
Basic setting = 0
 New datum for minor axis Q332 (absolute):
Coordinate in the minor axis at which the TNC should
set the bolt-hole center.
Basic setting = 0
