1.3 3-axis and 4-axis transformations
Introduction
3-axis and 4-axis transformations are special types of the 5-axis transformation initially
described. Orientation of the tool is possible only in the plane perpendicular to the rotary axis.
The transformation supports machine types with movable tool and movable workpiece.
Kinematics variants
The variants specified in the following table apply both for 3-axis and 4-axis transformations.

Note: on types 24 and 40 *
In the case of transformation types 24 and 40, the axis of rotation and tool orientation can be
set so that the change in orientation takes place at the outside of a taper and not in a plane.
Zero position
Tool orientation at zero position is the position of the tool with G17 as the active working plane
and position of the rotary axis at 0 degrees.
