Example

The workpiece drawing shows holes (

1

to

4

) whose dimensions are

shown with respect to an absolute datum with the coordinates X=0
Y=0. Holes

5

to

7

are dimensioned with respect to a relative datum

with the absolute coordinates X=450, Y=750. With the

DATUM

SHIFT cycle you can temporarily set the datum to the position
X=450, Y=750, to be able to program holes

5

to

7

without further

calculations.
