nt can not fully play its role. In highspeed machining, should be chosen with milling, when the milling cutter involvement with the workpiece chip thickness as the greatest, and then gradually decreased. Highspeed machining suitable for shallow depth of cut, cutting depth of not more than mm, to avoid the location of deviation tool to ensure that the geometric precision machining parts. Ensure that the workpiece on the cutting constant load, to get good processing quality. Cutting a single highspeed milling pathcutting mode, try not to interrupt the process and cutting tool path, reducing the involvement tool to cut the number to be relatively stable cutting process. Tool to reduce the rapid change to, in other words when the NC machine tools must cease immediately, or Jiangsu, and then implement the next step. As the machine tool acceleration restrictions, easy to cause a waste of time, and exigency stop or radical move would damage the surface accuracy. In the mold of highspeed finishing, in each Cut, cut to the workpiece, the feed should try to change the direction of a curve or arc adapter, avoid a straight line adapter to maintain the smooth process of cutting. 3 Die in highspeed milling processing of Milling as a highly efficient highspeed cutting of the new method,in Mould Manufacturing has been widely used. Forging links in the regular production model, with EDM cavity to be 12 ~ 15 h, electrodes produced 2 h. Milling after the switch to highspeed, highspeed milling cutter on the hardness of HRC 6 0 hardened tool steel processing. The forging die processing only 3 h20min, improve work efficiency four to five times the processing surface roughness of ~ , fully in line with quality requirements. Highspeed cutting technology is cutting technology one of the major developments, mainly used in automobile industry and die industry, particularly in the processing plex surface, the workpiece itself or knives rigid requirements of the higher processing areas, is a range of advanced processing technology The integration, high efficiency and high quality for the people respected. It not only involves highspeed processing technology, but also including highspeed processing machine tools, numerical control system, highspeed cutting tools and CAD / CAM technology. Dieprocessing technology has been developed in the mold of the manufacturing sector in general, and in my application and the application of the standards have yet to be improved, because of its traditional processing with unparalleled advantages, the future will continue to be an inevitable development of processing technology Direction. 4 Numerical control technology and equipping development trend and countermeasure Equip the engineering level, level of determining the whole national economy of the modernized degree and modernized degree of industry, numerical control technology is it develop new developing new hightech industry and most advanced industry to equip (such as information technology and his industry, biotechnology and his industry, aviation, spaceflight, etc. national defense industry) last technology and getting more basic most equipment. Marx has ever said the differences of different economic times, do not lie in what is produced, and lie in how to produce, produce with some means of labor . Manufacturing technology and equipping the most basic means of production that are that the mankind produced the activity, and numerical control technology is nowadays advanced manufacturing technology and equips the most central technology. Nowadays the manufacturing industry all around the world adopts numerical control technology extensively, in order to improve manufacturing capacity and level, improve the adaptive capacity and petitive power to the changeable market of the trends. In addition every industrially developed country in the world also classifies the technology and numerical control equipment of numerical control as the strategic materials of the country, not merely take the great measure to develop one39。 s own numerical control technology and industry, and implement blockading and restrictive policy to our country in view of highgrade, precision and advanced key technology of numerical control and equipping. In a word, develop the advanced manufacturing technology taking numerical control technology as the core and already bee every world developed country and accelerate economic development in a more costeffective manner, important way to improve the overall national strength and national position. Numerical control technology is the technology controlled to mechanical movement and working course with digital information, integrated products of electromechanics that the numerical control equipment is the new technology represented by numerical control technology forms to the manufacture industry of the tradition and infiltration of the new developing manufacturing industry, namely the socalled digitization is equipped, its technological range covers a lot of fields: (1)Mechanical manufacturing technology。 (2)Information processing, processing, transmission technology。 (3)Automatic control technology。 (4)Servo drive technology。 (5)Technology of the sensor。 (6)Software engineering ,etc.. Development trend of a numerical control technology The application of numerical control technology has not only brought the revolutionary change to manufacturing industry of the tradition, make the manufacturing industry bee the industrialized symbol , and with the constant development of numerical control technology and enlargement of the application, the development of some important trades (IT , automobile , light industry , medical treatment ,etc. ) to the national economy and the people39。 s livelihood of his plays a more and more important role, because the digi。
