20. TWO–PATH CONTROL
FUNCTION
377
Two–path control can be used with a lathe that supports simultaneous
cutting by its two independently operating tool posts.
Two–path control can be used for a lathe that machines one workpiece
attached to one spindle with two tool posts simultaneously.
For example, while one tool post is performing outer surface machining,
the other tool post can perform inner surface machining, thus reducing
machining time dramatically.

Two–path control can be used for a lathe that machines a workpiece
attached to each of two spindles with two tool posts simultaneously. In
this case, each tool post operates independently of each other as if two
lathes were used, thus improving productivity.
