CNC machining center is an efficient automatic machine tool which is composed of mechanical equipment and CNC system and is suitable for machining complex parts. CNC machining center is one of the CNC machine tools with high output and wide application in the world.

CNC lathe feed processing route refers to the path that the lathe tool passes from the tool alignment point (or the fixed origin of the machine tool) until it returns to this point and ends the processing program, including cutting processing path and non-cutting idle travel path such as tool cutting and cutting.

The feed route of finishing is basically carried out in sequence along the outline of its parts. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke.

In CNC lathe machining, the determination of machining route should generally follow the following principles.

(1) should be able to ensure the accuracy and surface roughness of the machined workpiece.

② Shorten the machining route, reduce the idle travel time and improve the machining efficiency.

(3) try to simplify the workload of numerical calculation and simplify the processing procedure.

(4) for some repeated programs, subroutines should be used.
