Every work offset (G54 to G57, G505 to G599) consists of a coarse
offset and a fine offset. You can call the work offsets from any
sequential control program (coarse and fine offsets are added
together).
You can save the workpiece zero, for example, in the coarse offset,
and then store the offset that occurs when a new workpiece is
clamped between the old and the new workpiece zero in the fine
offset.
Fine offsets must be set up by the machine manufacturer.
Please refer to the machine manufacturer's instructions.
For instructions on specifying and calling work offsets, see Secs.
"Defining work offsets" and "Calling work offsets".
You always program coordinate transformations for a specific
sequential control program. They are defined by:
•
Offset
•
Rotation
•
Scaling
•
Mirroring
(See Sec. "Defining the coordinate transformations")
The total offset is calculated from the sum of all offsets and coordinate
transformations.
