Cycles for Coordinate Transformation
Cycles for coordinate transformation permit contours to be
• Shifted
Cycle 7 DATUM SHIFT
• Mirrored Cycle 8MIRROR IMAGE
• Rotated (in the plane) Cycle 10 ROTATION
• Enlarged or reduced Cycle 11 SCALING
Cycles for coordinate transformation are effective upon definition until
they are reset or redefined. The original contour should be defined in a
subprogram. Input values can be both absolute and incremental.
DATUM SHIFT
CYCL DEF: Select Cycle 7 DATUM SHIFT
Enter the coordinates of the new datum
To cancel a datum shift: Re-enter the cycle definition with the input
value 0.
9 CALL LBL1
Call the part subprogram
10 CYCL DEF 7.0 DATUM SHIFT
11 CYCL DEF 7.1 X+60
12 CYCL DEF 7.2 Y+40
13 CALL LBL1
Call the part subprogram
When combining transformations, the datum shift must be
programmed before the other transformations.
