Coarse and fine offsets
As the assignment of machine axes to channel axes and, in particular, to geometry axes, can
be different in all channels, there is consequently no unique cross-channel geometric
relationship between the channel axes. Therefore, only offset, scaling and mirroring is possible
for NCU-global frames. Rotations are not possible.
G58: Absolute axis-specific programmable work offset (coarse offset)
The absolute component of the translatory offset (coarse offset) is programmed axis-
specifically with G58. The additive component of the translatory offset (fine offset) is retained.
G59: Additive axis-specific programmable work offset (fine offset)
The additive component of the translatory offset (fine offset) is programmed axis-specifically
with G59. The absolute component of the translatory offset (coarse offset) is retained.
G59 can only be used when the fine offset has been released:
● MD18600 $MN_MM_FRAME_FINE_TRANS = TRUE
● MD24000 $MC_FRAME_ADD_COMPONENTS = TRUE
