Determination of CNC processing route

The feed processing path of a CNC lathe refers to the path that the turning tool travels from the tool setting point (or the fixed origin of the machine tool) to the point where it returns and ends the processing program, including the path of cutting processing and non cutting empty stroke paths such as tool cut in and out.

The feed routes for finishing machining are basically carried out in the order of their part contours. Therefore, the focus of determining the feed routes is to determine the feed routes for rough machining and empty stroke.

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

① The accuracy and surface roughness of the workpiece to be processed should be ensured.

② Minimize processing routes, reduce idle travel time, and improve processing efficiency.

③ Try to simplify the workload of numerical calculation and simplify the processing program.

④ For some reusable programs, subroutines should be used.
