The world's first controlled production line was born (1968) in 1968, the British company has developed a mechanical hair Springs first automatic line consisting of CNC machine tools, and soon, the US General Electric Company proposed a "prerequisite for factory automation is part machining CNC process and production processes programmed ", so, by the mid-1970s, there has been automated plant, factory automation has also started construction. From 1970 to 1974, due to a small computer controlled machine tools are widely used, there have been three technological breakthroughs. The first is the direct digital controller, so that a small computer to control multiple machines at the same time, a "control group"; the second is a computer-aided design, with a light pen to design and modify the design and calculation procedures; s Three are processed according to the actual situation and unexpected changes in the amount of feedback and automatically change the machining and cutting speed, there has been an adaptive control system for machine tools. After 100 years of ups and downs, family machine has become more mature, and truly become the mechanical field, "workhorses." The quality of the merits of the machine itself, had made a direct impact on the quality of the machine. Measure the quality of a machine are many, but mainly require good technology, serialization, universal, high degree of standardization, simple structure, light weight, reliable, and high productivity. Specific indicators are as follows: 1, the possibility of the possibility of process technology is the ability to adapt to different production requirements of the machine. General machine can be completed within a certain size range multi-process machining various parts radial drilling products, the possibility of a wider process, and thus the structure is relatively complex radial drilling supplies, adapted to the single and small batch production. Special machine can only be done one or several parts of a particular operation, the possibility of its narrow radial drilling technology, suitable for mass production, improve productivity, quality assurance process radial drilling machine price, simplified machine structure and reduce machine costs . 2. To ensure accuracy and surface roughness and surface roughness of precision machined parts, the machine itself must have a certain geometric accuracy, precision sports, driving accuracy and dynamic accuracy. Accuracy refers to the shape of the geometric accuracy between moving parts when the machine is not mutual position accuracy and major parts, positional accuracy. Geometric accuracy of machine tools have an important influence on the machining accuracy, and therefore is the main indicator for assessing the accuracy of the machine. Movement accuracy is the accuracy of the machine geometry when working speeds in the main components, the amount of change of geometry, the lower the motion accuracy.
