1.3.1 Coordinates definition
Sketch map of CNC turning machine is as follows:
Fig. 1-3
TAC-100XT uses a rectangular coordinate system composed of X, Z axis. X axis is
perpendicular with axes of spindle and Z axis is parallel with axes of spindle; negative
directions of them approach to the workpiece and positive ones are away from it.
There is a front tool post and a rear tool post of NC turning machine according to their
relative position between the tool post and the spindle, Fig. 1-4 is a coordinate system of
the front tool post and Fig. 1-5 is a rear tool post one. It shows exactly the opposite of X
axes, but the same of Z axes from figures. In the manual, it will introduce programming
application with the front tool post coordinate system in the following figures and
examples.
