- Operation description 2: When G43 (tool length compensation) is specified for a machine
with no axis crossing
Here is the case where no axis of the machine crosses any other axis.
It is assumed that sample program 1 is used.
In this example, the "BC type tool axis Z-axis" is used as the machine configuration.
It is assumed, however, that the tool axis does not cross the B-axis while the B-axis
and C-axis cross each other.

Block N4 : Shifts the control point to point Z30.0 in the feature coordinate system.
Block N5 : Exerts automatic control over the rotation axes.
Block N6 : An intersection offset vector between the tool axis and the B-axis with
automatic control for rotation axes taken into consideration is output in
the feature coordinate system.
Performs tool length compensation in the feature coordinate system.
The tool center point is shifted to the origin of the feature coordinate
system.
This is also true when the B-axis does not cross the C-axis.
For explanations about the offset to be applied when the B-axis does not cross the
C-axis, see the descriptions about parameters No.19712, No.19713, and No.19714.
Fig.3 (g) shows the behavior of the machine when it runs sample program 1.
