21. TWO–PATH CONTROL
FUNCTION
591
The two–path control function is designed for use on a machining center
where two systems are operated independently to simultaneously perform
cutting.
The operations of two path are programmed independently of each other,
and each program is stored in program memory for each path. When
automatic operation is to be performed, each path is activated after
selecting a program for machining with path 1 and a program for
machining with path 2 from the programs stored in program memory for
each path. Then the programs selected for the paths are executed
independently at the same time. When path 1 and path 2 need to wait for
each other during machining, the waiting function is available (Section
21.2)
Just one MDI is provided for the two paths. Before operation and display
on the MDI, the path selection signal is used to switch between the two
paths.

Simultaneous operation of the two paths or the operation of
only a single tool post can be selected by pressing a key on
the machine operator’s panel. For details, refer to the
manual supplied by the machine tool builder.
