This function is valid for Z-axis. It becomes effective from
a
block in
which G43
or
G44 and H code
are
commanded. It is canceled by the
HOO
or
G49 command.
(2)
Tool position offset
(used
for simple offset of tool
radius)
This function is valid for X. Y, and Z axes
(>:•
4th-and 5th

This
function is only valid in blocks where
any
G code from G45
to
G48 is
commanded.
(3)
Tool radius offset CM*
(used
to
offset the tool radius of
a complex form)
This function is valid for
an arbitrary machining form. It is effective
for theXY plane
and YZ
or
ZX
plane.
This function becomes effective
from when G41 or G42 and D code are commanded. It is canceled
by
the G40
command.
