Basic Theory
The programmable rotation ROT, AROT can be used:
The rotation is performed in the current plane G17, G18 or G19 using the
value of RPL=...specified in degrees.
ROT RPL=... ; programmable rotation offset (absolute).
AROT RPL=… ; programmable offset, additive to existing offset
(incremental)
ROT ; without values, clears old commands for offset
N10 G17
N20 AROT RPL=45 additive 45 degree rotation

Coordinate

ROT AROT
A scale factor can be programmed for all axes with SCALE, ASCALE. The
path is enlarged or reduced by this factor in the specified axis. The cur-
rently set coordinate system is used as the reference for the scale
change.
SCALE X...Y... Z... ; programmable rotation offset (absolute)
ASCALE X...Y... Z... ; programmable offset, additive to existing offset
(incremental)
If a program contains SCALE or ASCALE, this must be programmed in a
separate block.
