the last century at the end of 70s to early 80s, due to the rapid development of microelectronics technology, modern digital manufacturing technology and equipment has gained unprecedented development and wide application, greatly promoted the improvement of the manufacturing labor productivity, the development of manufacturing industry has entered a new era: by relying mainly on the improvement of ability to rely mainly on labor the progress of science and technology. The application of new technology has greatly accelerated the growth rate of labor productivity in the manufacturing industry.

　　we know that the constant pursuit of labor productivity is the eternal theme of the manufacturing industry, which is determined by the survival and development of the manufacturing industry itself. According to the results of the International Economic Cooperation Organization (OECD), the change of price will lag behind the increase of cost, thus forming the "productivity gap", which is a long-term challenge to the manufacturing industry.

　　modern digital manufacturing technology is to meet the needs of the manufacturing industry to improve productivity and developed. As a complete manufacturing technology system, modern digital manufacturing technology is mainly composed of three parts: CNC machine tools, numerical control and digital control tools (international practice called "modern efficient tool"). These three subsystems are not only independent development, but also complement each other, promote each other, and constantly promote the improvement of labor productivity in the manufacturing industry.

　　in a modern and efficient tool for example, although the price is much higher than the traditional standard tool, but because of its excellent performance, the processing quality and processing efficiency is greatly improved, so that the manufacturing industry to improve labor productivity, reduce production cost, obtain greater benefits, the benefits of leverage ratio reached more than five times. For example, the United States each year, the amount of spending on the tool is $about 3000000000, while the manufacturing industry to improve efficiency and reduce costs, but the income reached $15 billion.
