Please note while programming:
Cycle parameters
 Center in 1st axis Q273 (absolute): Bolt-hole circle
center (nominal value) in the reference axis of the
working plane. Input range -99999.9999 to
99999.9999
 Center in 2nd axis Q274 (absolute): Bolt-hole circle
center (nominal value) in the minor axis of the working
plane. Input range -99999.9999 to 99999.9999
 Nominal diameter Q262: Enter the approximate bolt-
hole circle diameter. The smaller the hole diameter,
the more exact the nominal diameter must be. Input
range 0 to 99999.9999
 Angle of 1st hole Q291 (absolute): Polar coordinate
angle of the first hole center in the working plane.
Input range -360.0000 to 360.0000
 Angle of 2nd hole Q292 (absolute): Polar coordinate
angle of the second hole center in the working plane.
Input range -360.0000 to 360.0000
 Angle of 3rd hole Q293 (absolute): Polar coordinate
angle of the third hole center in the working plane.
Input range -360.0000 to 360.0000
 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
 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
 Number in table Q305: Enter the number in the
datum/preset table in which the TNC is to save the
coordinates of the bolt-hole circle center. If you enter
Q305=0 and Q303=1, the TNC automatically sets the
display so that the new datum is on the bolt-hole
circle center. If you enter Q305=0 and Q303=0, the
TNC writes the bolt-hole circle center in line 0 of the
datum table. Input range 0 to 99999
 New datum for reference axis Q331 (absolute):
Coordinate in the reference axis at which the TNC
should set the bolt-hole circle center. Default setting
= 0. Input range -99999.9999 to 99999.9999
Before a cycle definition you must have programmed a
tool call to define the touch probe axis.
