As the promotion of informatization of our country manufacturing industry and development, the digital technology such as enterprise of digital workshop, number and digitlization service already made the important mark that industry technology progresses, also be the important step that enhances company core competition ability. The number is made mix as new production technology production mode, already became the powerful motive force that urges 21 centuries manufacturing industry to develop ahead, its are important diagnostic expression is in: Product figure conveys without 2 justice sexes, but sex of put sb in a very important position (formalization description and express) ; The product is developed and produce those who taste function to be able to forecast a gender (producibility analysis and product function beforehand appraise) ; Production activity is mixed to distance, time positional independent character (network environment) . Digital equipment is the base that the number creates, also be the powerful motive force that urges 21 centuries to make equipment development and innovation, have powerful and agile process capability not only, and have powerful information treatment and processing capacity. Current, the number makes the problem that equipment needs to consider and solves with the number basically include: The number that the number of much physics field builds model, treatment and figuration course is emulated, facilities of treatment of number of high spirit of fast product development, high speed and number measure equipment to wait. Current situation of the research limits that article analysis number is made and the number equips, research and development trend, discuss its science connotation and structural system, look into its to study foreground, to improve our country manufacturing industry digitlization, informatization, intelligence changes a standard, enhance the product innovation ability of the enterprise and core competition ability, stimulative economy can grow continuously, seek theory and technical support from fountainhead, exploration number creates the problem of crucial science and technology with digital equipment domain. Current situation of domestic and international research and development trend from 1998 Er of American vice president dagger puts forward " digital earth " since the concept, city of catchment of such as number, number, digitlization lives, the digital human body and digital war new idea that is prefix with the number is many emerge in large numbers. The number is made what digitlize tide for the whole world namely is important one annulus, its connotation includes digital design, number to make equipment and number create the research field such as the technology, in products plan, in coordination development, production process and the respect such as production mode bring a series of changing. In recent years, as the promotion of informatization of our country manufacturing industry and development, the digital technology such as enterprise of digital workshop, number and digitlization service already made the important mark that industry technology progresses, also be the important step that enhances company core competition ability. The number is made and digital equipment is an open research field, also be the research domain of a rapid development. The crucial technology issue that studies urgently has: (1) object form the number of space and space of quantity coming back shows, geometrical computation and geometrical inference; (2) the interact rule of many physics field and its number show; (3) tie of geometric constraint, physics and product function are restrained; CNC MillingCNC Machining
