Hypothetical coordinate system
There are three types of hypothetical coordinate system: table coordinate system, feature coordinate systemand tool axis
coordinate system.
 Tool axis coordinate system
On table tilt type machines, axes move with the rotation of the rotary axis in the coordinate system fixed on the table.
(Example) Table tilt A-C axis
A0. Z(+)
C0.
X(+)
Y(+)
 Feature coordinate system
On all types of machines, the coordinate system does not move with the rotation of the rotary axis in the coordinate system
executing a program command such as the inclined surface machining command.
(Example) Combined tilt B-C axis
B45.
C270.

 Tool axis coordinate system
On tool tilt/combined tilt type machines, axes move with the rotation of the tool axis in the coordinate system in which the Z
axis direction becomes parallel to that of the tool axis.
