Please note while programming:
Danger of collision!
To prevent a collision between the touch probe and
workpiece, enter high estimates for the lengths of the
first and second sides.
Before a cycle definition you must have programmed a
tool call to define the touch probe axis.
Cycle parameters
U Center in 1st axis Q321 (absolute): Center of the stud
in the reference axis of the working plane. Input range
-99999.9999 to 99999.9999
U Center in 2nd axis Q322 (absolute): Center of the
stud in the minor axis of the working plane. Input
range -99999.9999 to 99999.9999
U 1st side length Q323 (incremental): Stud length,
parallel to the reference axis of the working plane.
Input range 0 to 99999.9999
U
2nd side length Q324 (incremental): Stud length,
parallel to the minor axis of the working plane. Input
range 0 to 99999.9999
U 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
U
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
U 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
