Explanation
- Coordinate system
The following two coordinate systems are specified at different
locations: (See II-7)
1 Coordinate system on part drawing
The coordinate system is written on the part drawing. As the
program data, the coordinate values on this coordinate system are
used.
2. Coordinate system specified by the CNC
The coordinate system is prepared on the actual machine tool
table. This can be achieved by programming the distance from
the current position of the tool to the zero point of the coordinate
system to be set.

Concrete programming methods for setting coordinate systems
specified by the CNC are explained in II-7, "COORDINATE
