ABSTRACT
Numerical control technology and the important position of nc machine tools in the modern machinery manufacturing and huge benefits, shows its basic industry modernization in the country's strategic role, and has e a traditional mechanical manufacturing industry upgrading transformation and automation, flexibility, integration and important means of production and marking. CNC technology C machine tools are widely used for industrial structure, product category and grade of the machinery manufacturing and production mode has brought the revolutionary change. Nc machine tool is the most important modern processing workshop and equipment. It is the development of information technology (1 t) and manufacturing technology (MT) bination with the result of the development. Modern CAD/CAM, FMS, CIMS, agile manufacturing and intelligent manufacturing technology, are based on numerical control technology.
Machine tools of numerical control machine tool is the equipment manufacturing industry, is the cornerstone of modern manufacturing technology and equipment is to guarantee a high and new technology industry development and the strategy of national defense modernization equipment. Under the circumstances of global advocacy of green manufacturing, numerical control machine tool transformation has e the hot spot. It includes mon machine tool nc transformation and upgrading C machine tools.
