Local coordinate system
(workpiece coordinate system)
(1) With N1, the origin is shifted by [x, y, z] = (10., 0, 0) in respect to the currently set local
coordinate system. The new G68.1 program coordinate system (A in the figure above)
rotated -30° in the counterclockwise direction using the Y axis as the center is set.
(2) With N2, the origin is shifted by [x, y, z] = (0, 10., 0) in respect to the newly set G68.1 program
coordinate system (A in the figure above). The new G68.1 program coordinate system (B in
the figure above) rotated +45° in the counterclockwise direction using the X axis as the
center is set.
(3) With N3, the G68.1 program coordinate systems that have been set are all canceled, and the
state prior to where the first G68.1 has been commanded is returned.
