CNC Machining lathe feed processing route refers to the tool from the knife point or machine fixed starting point began to move back to the point and finish the path through the processing program. Finishing of the feed line is along its outline parts basically, so the important work of ensuring feed line is to determine the rough and empty stroke of the feed line. In processing of CNC vowin.cn/en/News/news1251.html' target='_blank'>machining, processing route determination generally to follow the principle of the following aspects:

1. Machined components should be ensured the accuracy and surface roughness.

2. Making the processing route is the shortest to reduce the travel time, and improve processing efficiency.

3. Try to simplify the work of numerical calculation and processing procedures.

4. For some reuse program, there should use the subroutine.
