NC lathe feed processing route refers to the path that the turning tool moves from the tool setting point (or fixed origin of the machine tool) until it returns to that point and ends the machining program, including the path of cutting processing and non-cutting such as cutting in and out of the tool Empty travel path.

The feed route for finishing is basically performed along the contour of its parts. Therefore, the focus of determining the feed route is to determine the feed route for rough machining and empty stroke.

In CNC lathe processing, the determination of processing routes generally follows the following principles.

① The precision and surface roughness of the workpiece to be processed should be guaranteed.

② Make the processing route the shortest, reduce the idle travel time, and improve the processing efficiency.

③ Simplify the workload of numerical calculation and simplify the processing procedures.

④ For some reusable programs, subroutines should be used
