Determination of CNC machining route

CNC lathe feed processing route refers to the path through which the turning tool starts to move from the tool setting point (or the fixed origin of the machine tool) until it returns to this point and ends the machining program, including the cutting processing path and non-cutting such as tool cutting and cutting Empty travel path.

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

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

① It should be able to ensure the accuracy and surface roughness of the workpiece to be processed.

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

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

④ For some reusable programs, subprograms should be used
