【正文】 rocess and 5 axles are processed and can be realized on the same lathe, can also realize the inclined plane and pour the processing of the hole of awls. Germany DMG Company exhibits the DMUVoution series machining center, but put and insert and put processing and 5 axles 5 times to link and process in once, can be controlled by CNC system or CAD/CAM is controlled directly or indirectly. Bee the main trend of systematic development of contemporary numerical control intelligently, openly, workedly. The numerical control equipment in the 21st century will be sure the intelligent system, the intelligent content includes all respects in the numerical control system: It is intelligent in order to pursue the efficiency of processing and process quality, control such as the selfadaptation of the processing course, the craft parameter is produced automatically。t meet highspeed development of modern numerical control technology39。s livelihood of his plays a more and more important role, because the digitization that these trades needed to equip has already been the main trend of modern development. Numerical control technology in the world at present and equipping the development trend to see, there is the following several respect [1 ] in its main research focus. 5 A highspeed, high finish machining technology and new trend equipped The efficiency, quality are subjavanufacturing technology. Highspeed, high finish machining technology can raise the efficiency greatly , improve the quality and grade of the products, shorten production cycle and improve the market petitive power. Japan carries the technological research association first to classify it as one of the 5 great modern manufacturing technologies for this, learn (CIRP) to confirm it as the centre in the 21st century and study one of the directions in international production engineering. In the field of car industry, produce one second when beat such as production of 300,000 / vehicle per year, and many variety process it is car that equip key problem that must be solved one of。英文資料 Highspeed milling Highspeed machining is an advanced manufacturing technology, different from the traditional processing methods. The spindle speed, cutting feed rate, cutting a small amount of units within the time of removal of material has increased three to six times. With high efficiency, high precision and high quality surface as the basic characteristics of the automobile industry, aerospace, mold manufacturing and instrumentation industry, such as access to a wide range of applications, has made significant economic benefits, is the contemporary importance of advanced manufacturing technology. For a long time, people die on the processing has been using a grinding or milling EDM (EDM) processing, grinding, polishing methods. Although the high hardness of the EDM machine parts, but the lower the productivity of its application is limited. With the development of highspeed processing technology, used to replace highspeed cutting, grinding and polishing process to die processing has bee possible. To shorten the processing cycle, processing and reliable quality assurance, lower processing costs. 1 One of the advantages of highspeed machining Highspeed machining as a dieefficient manufacturing, highquality, low power consumption in an advanced manufacturing technology. In conventional machining in a series of problems has plagued by highspeed machining of the application have been resolved. Increase productivity Highspeed cutting of the spindle speed, feed rate pared withtraditional machining, in the nature of the leap, the metal removal rate increased 30 percent to 40 percent, cutting force reduced by 30 percent, the cutting tool life increased by 70% . Hardened parts can be processed, a fixture in many parts to be pleted rough, semifinishing and fine, and all other processes, the plex can reach parts of the surface quality requirements, thus increasing the processing productivity and petitiveness of products in the market. Improve processing accuracy and surface quality Highspeed machines generally have high rigidity and precision, and other characteristics, processing, cutting the depth of small, fast and feed, cutting force low, the workpiece to reduce heat distortion, and high precision machining, surface roughness small. Milling will be no highspeed processing and milling marks the surface so that the parts greatly enhance the quality of the surface. Processing Aluminum when up , pieces of steel processing at up to ~ . Cutting reduce the heat Because the main axis milling machine highspeed rotation, cutting a shallow cutting, and feed very quickly, and the blade length of the workpiece contacts and contact time is very short, a decrease of blades and parts of the heat conduction. Highspeed cutting by dry milling or oil cooked up absolute (mist) lubrication system, to avoid the traditional processing tool in contact with the workpiece and a lot of shortings to ensure that the tool is not high temperature under the conditions of work, extended tool life. This is conducive to processing thinwalled parts Highspeed cutting of small cutting force, a higher degree of stability, Machinable with highquality employees pared to the pany may be very good, but other than the pany39。 (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
