Abstract
Numerical control machine C machine tools from position of the flexible manufacturing system is processing machinery and equipment to transform traditional industries, the number of enterprises to build an important foundation, it has been the development of people's attention. Numerical control system of flexible automation for its superior performance, outstanding accuracy and stable, agile and functional diversity caused by the world. It opened up a machinery to set a precedent for the development of mechanical-electrical integration, C milling machine technology to advanced manufacturing technology to e a core technology. Through continuous research and development and the deepening of the application of information technology to promote the performance and quality C milling machine further enhanced to bring C milling machine has e the national economy and national defense construction and development of an important manufacturing equipment. Came into being C milling machine is used in the production of large-scale practice.
NC (numerical control) machine is the representative of advanced equipment in current mechanical manufacture industry. With the developing of modem manufacture industry, to design machine with NC, especially to study the economy milling-machine's design with NC has ing more urgent and arduous for us. After introducing NC machine's history and current status and the analysis of similar type
