4.
Tool radius compensation-C is applied
to
the
movement
shape that is
offset by tool length offset and tool position offset. As
a rule,
avoid
applying tool radius compensation-C after using tool position offset
to
correct
the tool radius.

5. Before G41
or
G42 and G40
can be commanded, GOO
or
G01 and F code
must
be commanded in the same block or preceding block.
6. If plane-specifingG codes Gl7
to
G 19
are
commanded in offset
to
change
the offset plane, alarm
"183" results.
7. Exact round
cutting
(G12, G13)
and canned cycle (G73, G74, G76, G77,
G80to G89)are
commanded
in
the tool radius
compensation
cancel mode.
Exact round cutting
itself has the tool radius
compensation function.
Commanding
these codes in the offset mode results in alarm "182."
8.
Tool radius compensation-C is also possible for circular interpolation
by radius specification.
9. Subprograms (M98, M99)
may
be commanded during the offset mode
without
any
problem.
10.
If simultaneous three-axis
movement
(
* up to
five axes) is commanded
in
the offset mode, offset
is
applied
to
the projected diagram
onto
the
offset
plane specified by G17, G18,
or
G19.
