附錄 附錄1 英文原文： High-speed cutting processing in mold manufacture application A.J.G. Nuttall *, G. Lodewijks Abstract The current mold application is widespread, also had the very big development with it related die making technology. At present, used the high-speed cutting production mold already to become the die making the general trend. In some mold Manufacturer, the high speed engine bed big area substitution electrical discharge machine, the high-speed cutting production mold already gradually became the die making the general trend. It can improve mold's size, the shape and the surface roughness, reduces even omits the manual sharpening, thus reduces production cost and the reduction manufacturing cycle. This article through to the traditional mold processing craft and the high speed mold processing craft's contrast, elaborated the high-speed cutting processing superiority. In the article also briefly introduced the high-speed cutting processing in the processing craft aspect key technologies. Keywords High-speed cutting Grinding tool Grinding tool processing Process technology 1 Introduction 1.1 Introduction Along with the advance in technology and the industry swift development, the mold already became in the industrial production to use the extremely widespread main craft to equip now. The mold takes the important craft equipment, in Industry sectors and so on consumable, electric appliance electron, automobile, airplane manufacture holds the pivotal status. The manufactured products components rough machining 75%, the precision work 50% and the plastic parts 90% will complete by the mold. At present the Chinese mold market demand has reached 50,000,000,000 Yuan scales, our country die making market potential is huge. The mold is one kind of special-purpose tool, uses in forming () each metal or the nonmetallic material needs the components the shape product, this kind of special-purpose tool general designation mold. The mold is in the industrial production the most foundation equipment, is realizes the few cuttings and the non-cutting essential tool. The mold has widely used in the industrial production each domain, like the automobile, the motorcycle, the domestic electric appliances, the instrument, the measuring appliance, the electron and so on, in them 60%~80% components need the mold to carry on the manufacture; The highly effective production in enormous quantities's, bolt, nut and gasket standard letters and so on plastic also need the mold to produce; The engineering plastics, the powder metallurgy, the rubber, the alloy compression casting, the glass formation and so on need to use the mold to take shape. 1.2 High-speed cutting process technology As the name suggests, the high-speed cutting, first is the high speed, namely must have the high spindle speed, for instance 12000r/min, 18000r/min, 30000r/min, 40000r/min, even also had a higher rotational speed still in the experiment; On the other hand, should also have the bigger to feed quantity, like 30000mm/min, 40000mm/min, even 60000mm/min; Has is after again the rapid traverse, trades fast the knife, the main axle trade the knife, from the static state arrives its needs rotational speed rise time and so on, only then achieved the above standards to be able to call it high speed. Next is must aim at the different processing object, the different degree of hardness, the different material quality, the different shape to choose the corresponding reasonable parameter, but cannot pursue constantly to be high speed and be high speed, regarding the die space processing, the shape is specially complex, but the cutting tool diameter is also small time, because cutting tool's path is not the simple translation, but is the curve, even has right angle corner time, technological parameter rational especially important, if because wants to maintain the identical feed rate carries on the orthogonal cutting, will not be able to do well will cause as a result of the engine bed moving part's huge inertia the cutting tool will make when the bend angle movement to break suddenly, but the variable motion can, becauseMovements and so on acceleration and deceleration create the thickness of cutting the instantaneous change, but causes the cutter change to enable the work piece surface to have cuts, from this causes the processing drop in quality, therefore, in view of the different processing object, needs the programmers to choose the reasonable cutting tool path, optimized cutting parameter; On the other hand, according to needs to choose the suitable cutting velocity, only then can display the high-speed cutting truly like the strong point. The high-speed cutting (HSC) is an advanced technique of manufacture which for the past ten years rapidly rises. Because the high-speed cutting technology has the cutting efficiency to be high, the processing quality high, can process the hard steel stock and the good efficiency directly, causes profession and so on aviation, mold, automobile, light industry and information production efficiencies and the manufacture quality obviously enhances, and causes the processing craft and the equipment corresponding renewal. Therefore is similar to the numerical control technology is the same, the high-speed cutting and the high speed processing have become in the 21st century a machine-building industry influence profound technological revolution. At present, adapts the HSC request high speed machining center and other high speed numerically-controlled machine tool has assumed the popularization tendency in the developed country, our country recently is also speeding up the development. The high-speed cutting processing is faces for the 21st century a high technology and new technology, it is one kind is different with the traditional processing processing way. Compares with it, the high-speed cutting processing main axle rotational speed high, cuts high for the speed, the cutting quantity is small, but in the unit time material excises the quantity to increase 3 ~ 6 times actually. It take the high efficiency, the high accuracy and the high surface quality as the basic characteristic, in profession and so on in automobile industry, aerospace, mold manufacture and instrument measuring appliance has obtained the increasingly widespread application, and has obtained the significant technology economic efficiency, is the contemporary advanced manufacture technology important constituent. When with traditional way processing mold, often uses the electric spark machining, but the electrode design and makes itself is the technological process which time-consuming takes the trouble. But after uses the high-speed cutting processing, because the narrow and small region processing realization and the high grade superficial result, let the electrode the utilization ratio reduce greatly. Moreover, makes the electrode with the high speed mill also to be possible to make the production efficiency to enhance to a new scale. The major part mold may use the high-speed cutting technology to process, like the forging die, the compression casting mold, cast with the blow molding mold and so on. Hammers the cavity body shallowly, the cutting tool life is long; Compression casting mold size moderate, the productivity is high; Casts with the blow molding mold general size small, quite is economical. 2 the high-speed cutting processing mold relative tradition processes the mold the superiority 2.1 Enhances the productivity In the high-speed cutting the main axle rotational speed and enters for the speed enhancement, may enhance material removing rate. At the same time, the
