Designation
of
compensating
plane
The
plane
in
which tool
radius
compensation
is
made is
designated
by
G17,
G18,
G19.
They
are
G
codes
of
B
group.
The

plane
(G17)
is
in
effect
at
the time
power
is
turned
on.

Make
sure
to
designate
a
G
code
for
plane
designation
in
the
same
block
as
that
of
G41,
G42
or
in
a
preceding
block.

Method
of
entry
into
compensation
mode
G41
When
G41
(G42)
is
programmed,
the
tool
moves
to
an
offset
position
with
the
distance
equal
to
the
radius.
The
offset
position
is
on
the normal
line
at
the
start
point
of
the
block
immediately
after
G41
(G42).
If
no
coordinate
instruction
is
programmed
in
the
block
of
G41
(G42),
movement
is made
by
the
offset
value
only.
Because
G41
(G42)
accompanies
a
movement,
it
is
necessary
to
program
GOO
or
G01 for
a
G
code
in
group
A. An
input
error
(alarm
code
"0615")
oc¬
curs
if
a
G
code
other than
GOO,
G01
is
pro¬
grammed.
