code. It is calculated inside the control unit, and its direction is up-dated in accordance with the
progress of the tool feed of each axis. This offset vector (it is called vector in the following description)
generates from the control unit, so that the tool offset movement can be calculated, and the actual
path of tool radius offset programmed path can be carried out. This offset vector is deleted by reset.
This vector varies from the tool movement, it is very important to comprehend the vector when
the program is performed. Read the following description and distinguish how the vector generates.
3.6.3.4 Plane selection and vector
Offset calculation is carried out in the plane determined by G17, G18 and G19. This plane is
called the offset plane. For example, the offset value can be carried out using the (X, Y) or (I, J) in
block and then the vector is calculated after the XY plane has been selected. The axis is not affected
for the coordinate value which is not in the offset plane. The programmed values are used as they
are.
In simultaneous 3 axes control, the tool path projected on the offset plane is compensated.
The shift among plane selection must be performed in the offset cancellation mode. If the plane
selection is performed in offset mode, an alarm (No.37) may generate.

When the offset plane with an additional axis set, an additional axis should be set in advance in
parameter to which parallels with one of the X Y Z axes. The offset plane can not be defined when it
does not parallel to the axis.
The offset plane with an additional axis and the G codes (G17, G18 and G19) can be specified
an additional axis simultaneously.

,
G41 and G42
The cancellation and generation of cutter compensation vector are specified by G40, G41 and
G42. The G40, G41 and G42 can be commanded with G00 or G01 simultaneously for deciding the
directions of offset vector and tool movement.
