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.
Fig2.1.7 Coordinate system specified by the CNC
The positional relation between these two coordinate system is determined when a workpiece
is set on the table.
Fig2.1.8 Coordinate system specified by CNC on part drawing
The tool moves on the coordinate system specified by the CNC in accordance with the
command program generated with respect to the coordinate system on the part drawing,and cuts a
workpiece into a shape on the drawing.
Therefore, in order to correctly cut the workpiece as specified on the drawing, the two
coordinate systems must be set at the same position.
To set the two coordinate systems at the same position, simple methods shall be used according
to workpiece shape, the number of machining.
