Movement Control Commands

3.1

The coordinate system

A tool position is clearly determined by coordinates within a coordinate system.
These coordinates are defined by program axes. For example, if there are 3 pro-
gram axes involved designated as X, Y, and Z, the coordinates are specified as:
X... Z...
The above command is called a dimension word.
Fig. 3-1
The following three coordinate systems are used to determine the coordinates:
1. Machine coordinate system
G code system A, B, C: G53
2. Workpiece coordinate system
G code system A:
G code system B, C:
3. Local coordinate system
G code system A, B, C: G52
