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.
Author in the access and search a lot and the design of relevant documents, to carry on the research of NC machining, and the teacher under the guidance of the patient, the first analysis of part process drawings, preparation of NC machining program using CATIA, the design of NC processing method of the parts, and uses VERICUT to the dynamic simulation of parts processing. Multi cavity to airplane parts in the design of object for processing, rough machining and finish machining the cavity milling and contour milling.
