If
no
movement
instruction
is
programmed
in
•
two
continuous
blocks,
offset
in
the
block
im¬
mediate
before
them
is1
made
on
the
normal
line
at
the
end-
point.
Where
movement
in
the
the
compensation
plane
cannot
be
programmed
in
two
or more
continuous
blocks
for
retracting
in
the
third
axis
or
the
like,
and
offsetting
on
the
normal
line
is
not
satisfactory,
a
dummy
block
can
be inserted
by
I,
J
or
K.

The
dummy
block
is
not
programmed
for
actual
movement
but
it
only
provides
data
re¬
quired
for
tool
radius
compensation
calcula¬
tion.
In
the
example
indicated
above,
an
instruction
that
is the
same
as
the
first
block
(N020)
of
restarted
movement
of
the
XY
plane
after
movement
of
Z
axis
is
programmed
as
a
dummy
by
I,
J.
I,
J,
K
are
used
as
the
addresses
of
this
dummy
instruction,
and
they
correspond
to
X, Y,
Z
axes
respective-
ly.
Suitably
use
them
in
accordance
with
the
plane
designation.
I:
Dummy
for
X
axis
-
command
J:
Dummy
for
Y
axis
command
K:
Dummy
for
Z
axis
command
Programmed
in
incremental
values
If
X-
•
•
Y-
•
of
N020
is
in
absolute
values
in
the above
example,
give
an
instruction
by
con¬
verting
into
incremental
values.
Note:
Make
a
dummy
block
as
follows
if
the
object
of
the
dummy
block is
circular
interpolation.
