G54 to G59 and G59 P~ - Select Work Offset Coordinate System

Details:
To select work offset #1, program: G54 and similarly for the first six offsets. The system-number-G-code pairs are: (1-G54), (2-G55), (3-G56), (4-G57), (5-G58), (6-G59).

To access any of the 254 work offsets (1 - 254) program: G59 P~ where the P word gives the required offset number. Thus G59 P5 is identical in effect to G58.

It is an error if one of these G-codes is used while cutter radius compensation is on.

See relevant chapter for an overview of coordinate systems.
