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:
X_Y_Z_
This command is referred to as a dimension word.
Z

40.0
50.0
25.0

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_.
