Touch Probe Cycles: Automatic Workpiece Inspection | MEASURE BOLT HOLE CIRCLE (Cycle 430, DIN/ISO:
G430)
Please note while programming:
Before a cycle definition you must have programmed a
tool call to define the touch probe axis.
Cycle 430 only monitors for tool breakage; there is no
automatic tool compensation.
Cycle parameters
Q273 Center in 1st axis (nom. value)? (absolute):
Bolt hole circle center (nominal value) in the
reference axis of the working plane. Input range
-99999.9999 to 99999.9999
Q274 Center in 2nd axis (nom. value)?
(absolute): Bolt hole circle center (nominal value)
in the minor axis of the working plane. Input range
-99999.9999 to 99999.9999
Q262 Nominal diameter?: Enter the diameter of
the hole. Input range 0 to 99999.9999
Q291 Polar coord. angle of 1st hole? (absolute):
Polar coordinate angle of the first hole center
in the working plane. Input range -360.0000 to
360.0000
Q292 Polar coord. angle of 2nd hole? (absolute):
Polar coordinate angle of the second hole center
in the working plane. Input range -360.0000 to
360.0000
Q292 Polar coord. angle of 3rd hole? (absolute):
Polar coordinate angle of the third hole center
in the working plane. Input range -360.0000 to
360.0000
Q261 Measuring height in probe axis? (absolute):

the touch probe axis in which the measurement
is to be made. Input range -99999.9999 to
99999.9999
Q260 Clearance height? (absolute): coordinate in
the touch probe axis at which no collision between
tool and workpiece (fixtures) can occur. Input
range -99999.9999 to 99999.9999
Q288 Maximum limit of size?: Maximum
permissible bolt hole circle diameter. Input range 0
to 99999.9999
