WARNING
1 When G45 to G48 is specified to n axes (n=1-6)
simultaneously in a motion block, offset is applied to
all n axes.
When the cutter is offset only for cutter radius or
diameter in taper cutting, overcutting or undercutting
occurs.
Therefore, use cutter compensation (G40 or G42)
shown in II-14.4 or 14.5.
2 G45 to G48 (tool offset) must not be used in the G41
or G42 (cutter compensation) mode.
