Cycles for Coordinate Transformations

Cycles for Coordinate Transformation

Cycles for coordinate transformation permit contours to be

 Shifted Cycle 7 DATUM SHIFT

 Mirrored Cycle 8 MIRROR 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.
