Numerical control machine (Numerical Control Machine Tools) referred to as CNC machine tools, which is a digital technology used in machine control technology. It in the process of machining a variety of control information of the digital code, said information carrier through the numerical control device input. After processing by the numerical control device controls the signal sent to control the machine movements, by drawing the shape and size requirements, will be automatically processed by the parts. CNC machine tools can solve the complex, sophisticated, low-volume, multi-species processing of parts is a flexible, high-performance automated machine tools, the representative of a modern machine tool control technology direction for the development of the Electrical and Mechanical Services is a typical integration products。CNC technology is a modern development of automatic control technology is digital signal processing machine and a method of control. The scope of its coverage of many areas of technology: (1) machinery manufacturing technology; (2) information processing, processing, transmission technology; (3) automatic control technology; (4) servo drive technology; (5) sensor technology; (6) Software Technology and so on. CNC machining technology in recent years showed the trend of rapid development, in order to meet the needs of the market, the modern technology of CNC machine tool manufacturers make higher demands。
The subject of this design is the number of cars turning on. Paper shows the characteristics of CNC machining, spare parts during processing of the process to develop a reasonable NC process planning. The use of equipment for the do-it-yourself parts processing entities and a qualified parts processing. Through their hands-on learning in the past few years by the "Mechanical Drawing", "Auto CAD", "Machinery Manufacturing", "NC programming based on" "tolerance measurement and technology with the" subjects such as theory of knowledge theory consolidation, but also exercise capacity in our hands. This is not only a theoretical knowledge will learn the theory in the actual processing of the application, the theory and practice will be combined with an organic, constantly improve their capabilities.
this is what i got from the GOOGLE,it's not good enough`most of them are ridiculous``
