Second, the application of CNC machine tools: CNC machine tools with a wide range of adaptability, processing object changes only need to change the input program instructions; processing performance than general-automatic machine, precision machining complex surfaces, and thus suitable for processing small batch, change frequent type, high precision, more complex shape of the workpiece, and can get a good economic effect. With the development of numerical control technology, the CNC system of machine tool increasing number of varieties, lathes, milling machines, boring machines, drilling machines, grinding machines, gear cutting machines and EDM machine tools. Addition to automatic tool change, machining centers, turning centers, multi-step processing of a loaded card. In 1948, the United States Parsons received a U.S. Air Force commissioned the development of an aircraft propeller blade profile template processing equipment. Model for the shape of complex, high precision, and general processing equipment is difficult to adapt to, therefore, put forward the idea of ??computer-controlled machine tools. Servomechanism laboratory of the Massachusetts Institute of assistance in 1949, the company began a CNC machine tool research and the success of the first trial in 1952 profiling by large vertical coordinate CNC milling machine milling refitted, and soon started production. The NC device using vacuum tube components, bulky, expensive, and only in the aviation industry and a few other special needs department for processing complex surface parts; 1959, made a transistor components and printed circuit boards, the CNC device to enter second-generation, smaller in size, costs decline; 1960, the relatively simple and economic point of control CNC drilling machines, CNC milling machine developed rapidly and straight-line control, CNC machine tools in the machinery manufacturing sector gradually promoted . In 1965 the third generation of integrated circuits NC device, small size, less power consumption, and reliability to raise prices further down, to promote the development of varieties of CNC machine tools and production. The late 1960s, has appeared in the direct control of the machine directly by a computer numerical control (DNC), also known as group control system; computer numerical control (CNC) controlled by small computer numerical control device to enter a small computer features into the fourth generation. In 1974, the successful development of the NC device of the microcomputer of a microprocessor and a semiconductor memory (MNC), which is the fifth generation of the NC system. The fifth-generation and third-generation CNC device features expanded doubled, while the volume is reduced to 1/20, 3/4 lower prices, reliability has also been greatly improved. In the early 1980s, with the computer software, hardware technology development, there has been man-machine dialogue automatic programming CNC device; CNC devices increasingly miniaturized, can be installed directly on the machine; CNC machine tools to further improve the degree of automation with automatic monitoring tool breakage and automatic detection workpiece.
