(Cont’d)
There
are
three
kinds
of
tool
offsets
as
follows:
(1)
Tool
length
offset
(used
to
offset
the
tool
length)
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
axes).
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.
