When
coordinate instructions
are
miBsing
in
two
or
more
blocks,
tool radius
compensation
be¬
comes
impossible
and
accurate
tool
path
can¬
not
be
obtained.
Therefore,
in
a
program
where
G41
or
G42
is
used,
ensure
that,
after
them,
two
or
more
blocks
without

in
the
compensation
plane
will

The
control
normally
reads
two
blocks
ahead
during
tool
radius
compensation
mode
and
calculates the
tool
path.
If
either
of
these
blocks
give
no
coordinate
instructions
such
as
G04
(dwell),
the
control
reads
