T
2-DIGIT
Tool
offset
commands
are
in
the
following
three
groups
.
Two
digits,
following
the
address
T,
specify
the
tool
number.
Leading
zeros
may
be
omitted.
*
Tool
position
offset
B
{for
compensation
for
tool
length
and
work
location)
This
offset
is
for
compensating
the
difference
of
tool
positions
in
X, Y,
and
Z
(4th
axis+)
axes.
This
instruction
is
executed
from
the
block
in
which
G43,
G44
are
given
together
with
H
or
D
code.
The instruction
is
cancelled
by
G49
com¬
mand.
T
Tool
number
The
figures
used
for
the
designation
of
tool
num¬
ber
are
determined
by
the
machine.
Refer
to
the machine tool
builder's manual.
When
a move
command
and
a
T
code
are
issued
simultaneously,
•
the
two
commands
are
executed
simultaneously,
•
Tool
position
offset
A
(for
simple
compensation
for
tool
radius)
This command is
for
compensating
for
tool
ra¬
dius
or
for
offsetting
the
tool.
It
is
effective
in
X, Y,
and
Z
axes
(4th
axis'*").
It
is
executed
only
to
the blocks
in
which
G45
through
G48
commands
are
given
together
with
H
or
D
codes.
•
Tool
radius
compensation
C+
(for
complicated
tool
radius
compensation)
This
code is
for
tool
radius
compensation
func¬
tions
effective
to
any
work
contours.
It
is
effec¬
tive
to
X-Y
plane
(Y-Z+,
or
Z-X
planesf).
The
command
is
executed
the
moment
G4
1
or
G42
is
given
together
with
an
H
or
D
code. The
command
is
cancelled
by
G40
code.
For
de¬
tails
of
these
compensations,
refer
to
2.14
PREPARATORY FUNCTIONS
(G-FUNCTIONS).
or
.
the
T
command is
executed
upon
completion
of
the
execution
of
the
move
command,
depending
on
the
design
of
the
machine.
For
this,
refer
to
the
machine
builder's
manual.
'
T
codes
are
modal,
and
therefore,
once
they
are
given,
they
remain
effective
until
another
T
command is
given.
•
T
code
commands
are
generally
for
making
automatic tool
changers
(ATC)
to
select
the
tool
number
to
be
used
next.
Therefore,
they
can
be
given
without
regard
to
the
G,
H
or
D
codes which
are
for
offsetting
for
the
length
or
radius
of
the
tool
currently
in
use.
2.10.2
STORAGE
OF
TOOL
OFFSET
VALUES
For the
three
groups
of
offsets,
all
the
necessary
offset
values
must
be
stored
in
memory
before¬
hand.
Up
to
99
offset
values
can
be
stored
in
the
tool
offset
memory.
