BASIC ROTATION over two studs (Cycle 402, DIN/ISO: G402,

Cycle parameters

1st stud: Center in 1st axis Q268 (absolute):
Center of the first stud in the reference axis of
the working plane. Input range -99999.9999 to
99999.9999
1st stud: Center in 2nd axis Q269 (absolute):
Center of the first stud in the minor axis of
the working plane. Input range -99999.9999 to
99999.9999
Diameter of stud 1 Q313: 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
Measuring height 1 in the probe axis Q261
(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
2nd stud: Center in 1st axis Q270 (absolute):
Center of the second stud in the reference axis
of the working plane. Input range -99999.9999 to
99999.9999
2nd stud: Center in 2nd axis Q271 (absolute):
Center of the second stud in the minor axis of
the working plane. Input range -99999.9999 to
99999.9999
Diameter of stud 2 Q314: 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
Measuring height of stud 2 in the probe axis
Q315 (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
Set-up clearance Q320 (incremental): Additional
distance between measuring point and ball tip.
Q320 is added to SET_UP (touch probe table). Input
range 0 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
Traversing to clearance height Q301: 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
