Generally, CNC machining usually refers to computer-controlled precision machining, CNC machining lathes, CNC machining milling machines, CNC machining boring and milling machines, etc. In NC lathe processing, the determination of processing route should generally follow the following principles.
1. The accuracy and surface roughness of the machined workpiece shall be ensured.
2. Make the processing route short, reduce the empty travel time, and improve the processing efficiency.
3. Try to simplify the workload of numerical calculation and simplify the processing procedure.
4. For some reusable programs, subroutines should be used.
