What is CNC precision machining?

General CNC machining usually refers to computer digital control precision machining, CNC machining lathes, CNC machining milling machines, CNC machining boring and milling machines, etc. The CNC lathe feed processing route refers to the path that the turning tool moves from the tool setting point (or the fixed origin of the machine tool) until it returns to this point and ends the processing program, including the cutting processing path and the non-cutting such as cutting in and out of the tool. Empty travel path. The feed route of finishing is basically carried out in sequence along its part contour, therefore, the key point of determining the feed route is to determine the feed route of rough machining and idle travel. In CNC lathe processing, the determination of the processing route generally follows the following principles. ①It should be able to ensure the accuracy and surface roughness of the workpiece to be processed. ②Make the processing route the shortest, reduce the idle travel time, and improve the processing efficiency. ③ Try to simplify the workload of numerical calculation and simplify the processing program. ④ For some repetitive programs, subroutines should be used.
