Since the competition of global manufacturing industry is increasingly intense, advanced manufacturing technologies appeared continuously. The general application of the modern Numerical Control Manufacturing technology, has made the processing cycle of the products shorten by a large margin, has improved the processing quality of the products, has accelerated the update of the products, and has strengthened the competitive power of the products. So the research of the process technology of numerical control has become the focal point of studying.
The manufacturing method changes a lot with the development of the computer technology in the modern society. Computer simulation saves a lot of time for the workers and greatly saves the cost of raw materials. Also computer simulation increases production efficiency. At present, most of the factory machines are used in CNC machine tools. CNC machining parts achieved the requirement both in the appearance and in the accuracy. To master the computer manufacturing technology for the engineering working in the field of aviation is imperative.
After looking up plenty of relevant articles, author researched the process technology of Numerical Control. Under the guidance of the teacher's patience,author analysis the mold of the part at first and according to the shape characteristics of parts , assure the method of processing. Finally utilized CATIA P3 V5R20 carrying on characteristic modeling and carry on Numerical Control establishment to process procedure and designed NC processing method of the part and try to find out the most reasonable method of processing .Thus the dynamic simulation Numerical Control of carrying on the part is processed. Regarding thread spindle as the target of processing in this design . author has used Rough Turning operation, Profile Finish Turning operation, Recess Turning operation, Groove Turning operation, Drilling, Reverse Threading. Further,the whole process of NC simulation under VERICUT is shown combining with designed model instance in CATIA.
