【正文】 rning is the most basic, the most mon method of cutting in production occupies a very important position. Turning for processing rotary surface, most of the surface of the workpiece with a rotating turning method of processing can be used, such as the external cylindrical surface, internal and external conical surface, face, groove, thread and turn shaped surface so the tool is mainly used for turning tools. In all types of metal cutting machine tools, the lathe is the most widely used category, accounting for 50% of the total number of machine tools. Lathe tool can car turning the workpiece, and can drill bits, reamers, taps and knurling tool drilling, reaming, tapping and knurling such an operation. According to the technical characteristics of form and structure of the layout of the different characteristics, can be divided into horizontal lathe lathe, floor lathes, vertical lathes, turret lathes and copying lathe, horizontal lathe, most of them. CNC Turning is a typical representative of modern manufacturing technology in all areas of manufacturing such as aerospace, automotive, tooling, precision machinery, household appliances and other industries has bee increasingly widely used, has bee an indispensable means of processing these industries. CNC machine tools for processing subqualified parts, the first part to be based on accuracy and drawing requirements, analysis identified ponents of the process, process parameters etc., using prescribed format for the preparation of numerical control programming code and the NC machining program suitable . CNC programming is important to note the specific system or machine tools, machine tool programming should be in strict accordance with the provisions of the manual programming. But in essence the content of CNC machining, the NC system of the instructions are actually processing the request should be set.
