14.4.1 General
- Inner side and outer side
When an angle of intersection created by tool paths specified with
move commands for two blocks is over 180deg., it is referred to as
"inner side." When the angle is between 0deg. and 180deg., it is
referred to as "outer side."
- Outer corner connection method
When the tool moves around an outer corner in cutter compensation
mode, the user can choose whether to connect the compensation
vectors with each other by linear interpolation or circular interpolation,
by setting bit 2 (CCC) of parameter No. 6008.
(1) Linear connection type (bit 2 (CCC)
of parameter No. 6008 = 0)
- Cutter compensation cancel mode
In any of the cases below, cutter compensation cancel mode is set. (The
cancel mode may not be set, depending on the specification of the
machine tool builder.)
(1)Immediately after power-up
(2)After the reset button on the MDI panel is pressed
(3)After the program is terminated by executing M02 or M30
(4)After execution of the cutter compensation cancel command (G40)
In cancel mode, the magnitude of a compensation vector is always 0,
and the tool center path matches a programmed path. A program must
end in cancel mode. If a program ends in cutter compensation mode,

Linear interpolation is used for
connection between the vectors.
Circular interpolation is used for
connection between the vectors.
(2) Circular connection type (bit 2
(CCC) of parameter No. 6008 = 1)
