【正文】 CNC is a closed ringopening implementing agencies. In a plex and changing environment under the conditions of processing tool in the process of position, workpiece material, spindle speed, feed rate, tool path, cutting depth, step, allowance and other processing parameters, not at the scene circumstances under external interference and realtime dynamic random factors, not by random amendment feedback control link CAD / CAM settings volume, in turn, affect the work of CNC machining efficiency and product quality. Clearly, the traditional fixed CNC system that controlled mode and closed architecture, limiting the CNC to the development of more intelligent control variables, can no longer meet the increasingly plex manufacturing process, therefore, the CNC technology in the potential for change inevitable. 2 CNC technology development trends Performance development direction (1) highspeed highprecision efficient speed, accuracy and efficiency of machinery manufacturing technology is the key performance indicators. As a result of the highspeed CPU chips, RISC chip, as well as multiCPU control system with highresolution detector of the absolute exchange digital servo system, taken at the same time improve the machine dynamic and static characteristics of effective measures, the highspeed highprecision machine has been efficient greatly enhanced. (2) Flexible includes two aspects: CNC system itself flexibility, NC system is modular in design, functional coverage, can be cut and strong, and easy to meet the needs of different users。CNC technology development trends 1 CNC system developments at home and abroad With the rapid development of puter technology, the traditional beginning of a fundamental change manufacturing, the industrial developed countries spent huge sums of money on the modern manufacturing technology research and development, to create a new model. In modern manufacturing systems, CNC technology is the key to technology, which bines microelectronics, puters, information processing, automatic detection, automatic control, such as the integration of advanced, a highprecision, highefficiency, flexible automation, and other characteristics, the manufacturing industry Flexible automation, integrated, intelligent play the pivotal role. At present, NC technology is undergoing a fundamental change, from a special closedloop control mode to generalpurpose realtime dynamic open all closedloop control mode. In the integrated on the basis of the CNC systems ultrathin, ultralight。 on the basis of the intelligent, integrated puters, multimedia, fuzzy control, neural work and other technical disciplines, NC system to achieve highspeed, highprecision, Efficient control, automatic processing can be amended to regulate pensation and the parameters for an online intelligent fault diagnosis and treatment of the work based on the CAD / CAM and CNC systems integration as one machine work, makes the central government centralized control of the group control processing. For a long time, China39。 group control system flexibility, wit
