When the origin of the workpiece coordinate system is on
the end face of a chuck, the length of the workpiece (L’) is
ignored. The machining allowance for the end face is not
included in workpiece length L’.
When a blank plate is machined, point X1 on the outer
surface is used.
When the chuck/tailstock barrier function, an optional NC function, is selected,
it replaces the chuck barrier function described in the previous section. For
details of this optional function, refer to the operator’s manual supplied with the
NC.
Chuck/tailstock barrier data can be displayed and entered by using the
