Fig.1.3.2 (a) Coordinate system
The following two coordinate systems are specified at different locations:
(See II–7)
(1) Coordinate system on drawing
The coordinate system is written on the 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 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.
