Program
"O'1
as
the axis
movement
instruc¬
tion,
when
movement
only
by
tool
offset
values
in
incremental
designation
(G91)
is
wanted.
NOTES:
•
If
the
offset
value is
changed
by
MDI
in
the
off¬
set
mode,
this
change
becomes
operative
from
the block
read
next.
•
Tool
position
offset
A
or
tool
radius
compensa¬
tion
C
can
be
applied
in
addition
to
tool
position
offset
B.
•
The direction
of
offset
by
tool
position
offset
B
is
determined
by
G43,
G44
regardless
of
desig¬
nation
of
mirror
image.
•
Tool
position
offset
B
is
independent
of
G
codes
(G17/G18/G19)
for
plane
designation.
•
G43,
G44,
G49
cannot
be
programmed
in
the
canned
cycle
mode.
An
input
error
occurs
when
they
are
programmed.
•
When
G92
is
programmed
in
an
offset
mode,
pro¬
gramming
of
absolute
zero
point
is
made
with
the
offset
value
added.
Program
G92
in
cancel¬
led
state
in
principle.
•
During
automatic
operation,
display
of
the
tool
offset
number
(H
code
number)
valid
for
each
axis
by
tool
position
offset
B
is
possible.

Offset
is
made
along
both
X
and
Y
axes
in
negative
direc¬
tion
by
tool
offset
value.
It
is
meaningless
to
give
a
sign
to
"0.
In
the
absolute
mode
(G90),
program
the
cur¬
rent
coordinate
command
value
of
the
respec¬
tive
axis.
That
is,
program
so
that the
in¬
cremental
movement
value
becomes
zero.
