(G42), the tool moves only' by
offset value.
When
a move
within the compensation plane is
not
commanded in
the block
next to
G41 (G42), the data in one more block ahead is
read in advance and
compensation is performed in
that block. In
this
way.
for blocks without move
command, continuous
two
blocks
can
be programmed.
If a move command within the
compensation plane is
not
provided in
three blocks
or more,
tool diameter compensation
starts
from the
next
block.
(b)
For offset
startup, movement
is made by considering offset, so that
the G code in
group
01
must
be GOO
or
G01. If G codes other than
GOO
or
G01 are commanded, alarm "180'' results. When offset is
entered in the GOO
mode,
offset points move
with each axis
independently positioned, so
attention should be
paid
to
possible
interference with the workpiece.
