Touch Probe Cycles: Automatic Measurement of Workpiece Misalignment | BASIC ROTATION over two studs

Cycle parameters

Q268 1st stud: center in 1st axis? (absolute):
Center of the first stud in the reference axis of
the working plane. Input range -99999.9999 to
99999.9999
Q269 1st stud: center in 2nd axis? (absolute):
Center of the first stud in the minor axis of
the working plane. Input range -99999.9999 to
99999.9999
Q313 Diameter of stud 1?: Approximate diameter
of the 1st stud. Enter a value that is more likely
to be too large than too small. Input range 0 to
99999.9999
Q261 Meas. height stud 1 in TS axis? (absolute):
coordinate of the ball tip center (= touch point
in the touch probe axis) at which stud 1 is to
be measured. Input range -99999.9999 to
99999.9999
Q270 2nd stud: center in 1st axis? (absolute):
Center of the second stud in the reference axis
of the working plane. Input range -99999.9999 to
99999.9999
Q271 2nd stud: center in 2nd axis? (absolute):
Center of the second stud in the minor axis of
the working plane. Input range -99999.9999 to
99999.9999
Q314 Diameter of stud 2?: Approximate diameter
of the 2nd stud. Enter a value that is more likely
to be too large than too small. Input range 0 to
99999.9999
Q315 Meas. height stud 2 in TS axis? (absolute):
coordinate of the ball tip center (= touch point
in the touch probe axis) at which stud 2 is to
be measured. Input range -99999.9999 to
99999.9999
Q320 Set-up clearance? (incremental): Define
an additional distance between measuring point
and ball tip. Q320 is added to SET_UP in the touch
probe table. Input range 0 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
Q301 Move to clearance height (0/1)?: 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
