CNC Lathe Feed processing route refers to the path from the start of tool setting point (or the machine’s constant origin) to returning to the point and ending the processing program. It includes the path of cutting and the path of non cutting empty stroke such as tool cut in and tool out.
The feed path of finish machining is basically carried out in sequence along the appearance of the parts. Therefore, the focus of confirming the feed path is to confirm the feed path of rough machining and empty stroke.
In the NC lathe processing, the affirmation of the processing route is usually in accordance with the following principles.
① The accuracy and surface roughness of the workpiece to be processed shall be guaranteed.
② It can shorten the processing route, reduce the time of empty travel and improve the processing efficiency.
③ Although the workload of numerical calculation is simplified and the processing program is simplified.
④ Subroutines should be used for some repeated procedures
