In cutter compensation C, two–dimensional offsetting is performed for a
selected plane. In three–dimensional tool compensation, the tool can be
shifted three–dimensionally when a three–dimensional offset direction is
programmed.
D Start up

dimensional tool
compensation)
Xp : X–axis or a parallel axis
Yp : Y–axis or a parallel axis
Zp : Z–axis or a parallel axis

When the following command is executed in the cutter compensation
cancel mode, the three–dimensional tool compensation mode is set:
D Canceling

compensation
When the following command is executed in the three–dimensional tool
compensation mode, the cutter compensation cancel mode is set:
When canceling the three–dimensional tool compensation mode and
tool movement at the same time
G40 Xp_ Yp_ Zp_ ;
or
Xp_ Yp_ Zp_ D00 ;
When only canceling the vector
G40;
or
D00;
D Selecting offset space
The three–dimensional space where three–dimensional tool compensation
is to be executed is determined by the axis addresses specified in the startup
block containing the G41 command. If Xp, Yp, or Zp is omitted, the corre-
sponding axis, X–, Y–, or Z–axis (the basic three axis), is assumed.
(Example)
When the U–axis is parallel to the X–axis, the V–axis is parallel to the
Y–axis, and the W–axis is parallel to the Z–axis
