【正文】 ork piece under, but should use inclines the knife way (monly used angle of bank for 20176。 Digital actuation system crawling control (Jerk control).C. Advanced inserts makes up the method (to insert based on the NURBS transect makes up), by obtains the good surface quality, the precise size and the high geometry precision. D. Pretreatment (Lookahead) function. The request has the large capacity cushion register, may read in advance and inspects many segments (for example the DMG engine bed to be possible to reach 500 segments, the Simens system may reach a 1000~2000 segment), in order to when is processed the superficial shape (curvature) changes may promptly adopt changes for measure and so on speed by avoids cutting and so on. E. The error pensatory function, including because the straight line electrical machinery, the main axle and so on gives off heat the hot error which causes to pensate, the quadrantal error pensates, the measurement system error pensates and so on the function. In addition, the mold highspeed cutting processing very is also high to the data transmission speed request. F. The traditional data connection, like the RS232 serial mouth transmission speed is , but many advanced processings centers have used the ether local area network (Ethernet) to carry on the data transmission, the speed may reach 200kb.5. Cooling lubricationThe high speed processing uses the belt coating the hard alloy tools, in high speed, the high temperature situation does not need the cutting pound, the cutting efficiency to be higher. This is because: The milling main axle high speed revolves, the cutting pound if achieved the cutting area, first must overe the enormous centrifugal force。 Uses the straight line electrical machinery then may enable to achieve 120m/ to the speedMin.(2) high acceleration.Has the good acceleration characteristic to the three dimensional plex curved surface silhouette high speed processing request actuation system, the request provides the driver which the high rapid advance or progress gives (to enter speed approximately 40m/ quicklyMin, the 3D outline processing speed is 10m/Min), can provide The engine bed manufacturer mostly uses the entire closed loop position servocontrol slightly to lead, the great size, the high grade ball bearing guide screw or leads greatly many guide screws. Along with the electrical machinery technology development, the advanced straight line electric motor already was published, and the success applied in the CNC engine bed. The advanced straight line direct motor drive enable the CNC engine bed no longer to have the mass inertia, in advance, question and so on lag and vibration, sped up the servo speed of response, increased the servocontrol precision and the engine bed processing precision.4. Numerical control systemThe advanced numerical control system is guaranteed the mold plex curved surface high speed processing quality and the efficiency key aspect, the mold highspeed cutting processing to the numerical control system basic request is: A. High speed numerical control return route (Digital control loop), including: 32 or above 64 bit parallel processors and hard disk。s polishing with to throw the light quantity. Thin wall mold work piece more and more needs which regarding some markets in, the high speed milling also may smoothly plete, moreover in the high speed milling CNC processing center, a mold attire clamps may plete the multiplex step of processing.The high speed processing technology has had the huge influence to the mold processing craft, changed the traditional mold processing to use the annealing → milling processing → heat treatment → to rub truncates or the electric spark machining →manually polishes, polishes and so on the plex long technical process, even might use the highspeed cutting processing substitution original plete working procedure. The high speed processing technology besides may apply in the hard mold cavity direct processing (in particular half precision work and precision work), in EDM aspect and so on electrode processing, fast type manufacture also obtained the widespread application. The mass productions practice indicated that, the application highspeed cutting technology may save in the mold following processing 80% handwork to grind the time approximately, saves the processing cost expense nearly 30%, the mold face work precision may reach 1 m, the cutting tool cutting efficiency may enhance one time.Second, high speed milling processing engine bedThe highspeed cutting technology is one of machining technology main development directions, it along with foundation technology the and so on CNC technology, microelectronic technology, new material and new structure development but steps a higher stair. Because the mold processes particular as well as high speed processing technology own characteristic, (processed engine bed, numerical control system, cutting tool to the mold high speed processing related technology and the craft system and so on) proposed processed a higher request pared to the traditional mold.1. High stable engine bed strut partThe highspeed cutting engine bed lathe bed and so on supports the part to be supposed to have very well moves, the static rigidity, hot rigidity and best damping characteristic. The majority of engine beds all use high grade, the high rigidity and Gao Kangzhang the gray iron took the strut part material, some engine bed panies also increase the high damping characteristic in the foundation polymer concrete, by increases its vibrationproof and the thermostability, this not only may guarantee the engine bed precision is stable, also may prevent when c
