6. CREATING MACHINING PROGRAMS
OPERATION
55
In the Two–path lathes, an NC–format machining program is created
separately for each tool post, tool post 1 or 2, and is stored. Each
NC–format machining program is totally independent.
In a conversational machining program, each machining process is
created separately for tool post 1 or 2. However, processes for both tool
posts are combined and stored as a one machining program. When a
certain conversational machining program is selected, a workpiece is
machined within the processes specified in the program for tool posts 1
and 2. Different machining programs cannot be executed for the two tool
posts.
The following figure shows how a conversational machining program is
executed.
