The number
of
tool
offset
value
memories available
differs
between
basic
and
optional
specifications.
The
maximum
value
of
tool
radius
value
is
±
999.999mm
(or
±99.9999
inches).

If
correction
of
a
step
difference
smaller
than
the
tool
radius
is
executed
in
the
M96
mode,
excessive
cut
may
occur.
If
performed
in
the
M97
mode,
insufficient
cut
may
result
(which
is
preferable
to
the
above,
however).
