Function
The statements for programmable frames apply in the current NC program. They function as
either additive or substitute elements:
● Substitute statement
Deletes all previously programmed frame statements. The reference is provided by the last
settable zero offset called (G54 to G57, G505 to G599).
● Additive statement
Appended to existing frames. The reference is provided by the currently set workpiece zero
or the last workpiece zero programmed with a frame statement.
Application example
1. Move the zero point of the workpiece coordinate system (WCS).
2. Rotate the workpiece coordinate system (WCS) to orientate a plane parallel to the desired
work plane.
