NOTES:-
An
input
error
occurs
if
G29
is
programmed
in
tool
radius
compensation
mode
(G41,
G42)
or
during
canned'
cycle
mode
(G73,
G76 G81
to
G89).

It
is
possible
to
specify
the
radius
of
the
tool
and
to
cause
automatic
tool
path
offset
by
this
value.
Store
the'offset
value
(tool
radius
value)
in
the
offset
value
memory
in
advance
by
MDI,
and
pro¬
gram
the tool
offset
number
correspond
to
the tool
radius value
by
a
D
code
in
the
program,
•
An
input
error
occurs
if
G29
is
given
without
execution
of
G28 after
the
control is turned
on

In
principle,
cancel
tool
offset
before
program-
mingG28
or
G29.
If
they
are
programmed
when
offset
is also
effective,
intermediate
positioning
point
B
will
also
be
offset,
and the
tool
passes
point
B'.
Tool
radius
compensation
is
programmed
with
G41,
G42
and is
cancelled
by
G40.
G41
and
G42
indicate
the
directions
of
tool
offset
with
respect
to
the
direction
of
movement.

when
the
sign
of
the

Make
sure
to
designate
a

in
the
