7 COORDINATE SYSTEM
By teaching the CNC a desired tool position, the tool can be moved to
the position. Such a tool position is represented by coordinates in a
coordinate system. Coordinates are specified using program axes.
When three program axes, the X-axis, Y-axis, and Z-axis, are used,
coordinates are specified as follows:
This command is referred to as a dimension word.

Coordinates are specified in one of following three coordinate systems:
(1) Machine coordinate system
(2) Workpiece coordinate system
(3) Local coordinate system
The number of the axes of a coordinate system varies from one machine
to another. So, in this manual, a dimension word is represented as IP_.
