adds

the
stored

offset
values
to
or
from
the
coordinate

mand
value
of
the
designated
axes.
It
is
mainly
used
for
tool
length
compensation
in Z
axis
and
offset
for

have
effect
on
the axis
programmed
in
the
block,
and
once
these
instructions
are
given, they
remain
valid
until
they
are
cancel¬
led
by
G49.
They
are
modal
for
each axis
un¬
like
G
codes
of
other
A
groups.

When
programming
G43,
G44,
G49,
the
G
code
of
group
A
should
be
GOO
or
G01.
An
input
error
occurs
if
a
command
is
given
in
G02,
G03
or
the
like.

cancels

of
all the
axes
simultaneously.
7.
Direction
of
offset
The
direction
of
offset
is determined
by
the
sign
of
the
tool
offset
value
designated
by
an
H
code
in
addition
to
the
G
code.
4.
When
programming
G43,
G44
designate
the
tool
offset
number
by
an
H
(or
D)
code
simul¬
taneously
with
designation
of
the
axis.

•
Pair
designation
of
axis and
H
code
is
necessary.
