【正文】 rve, 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 part39。 On the other hand, should also have the bigger to feed quantity, like 30000mm/min, 40000mm/min, even 60000mm/min。s, bolt, nut and gasket standard letters and so on plastic also need the mold to produce。s contrast, elaborated the highspeed cutting processing superiority. In the article also briefly introduced the highspeed cutting processing in the processing craft aspect key technologies. Keywords Highspeed cutting Grinding tool Grinding tool processing Process technology 1 Introduction 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 ponents rough machining 75%, the precision work 50% and the plastic parts 90% will plete 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 specialpurpose tool, uses in forming () each metal or the nonmetallic material needs the ponents the shape product, this kind of specialpurpose tool general designation mold. The mold is in the industrial production the most foundation equipment, is realizes the few cuttings and the noncutting 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% ponents need the mold to carry on the manufacture。附錄 附錄 1 英文原文： Highspeed cutting processing in mold manufacture application . 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 highspeed cutting production mold already to bee the die making the general trend. In some mold Manufacturer, the high speed engine bed big area substitution electrical discharge machine, the highspeed cutting production mold already gradually became the die making the general trend. It can improve mold39。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 craft39。 The highly effective production in enormous quantities39。 The engineering plastics, the powder metallurgy, the rubber, the alloy pression casting, the glass formation and so on need to use the mold to take shape. Highspeed cutting process technology As the name suggests, the highspeed cutting, first is the high speed, namely must have the high spindle speed, for instance 12020r/min, 18000r/min, 30000r/min, 40000r/min, even also had a higher rotational speed still in the experiment。 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 plex, but the cutting tool diameter is also small time, because cutting tool39。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。 Compression casting mold size moderate, the productivity is high。s forced oscillation, has guaranteed the good processing condition. Because the cutting force is too small, cut the hot influence to be small, causes the cutting tool, the work piece distortion to be small, maintained the size accuracy, moreover also caused the friction between the cutting tool work piece changes is small, the cutting destruction level thinned, the residual stress was small, has realized the high accuracy, the low roughness processing. The reduced cutting produces quantity of heat Because the highspeed cutting processing is the shallow cutting, simultaneously the feed rate is very quick, the knife edge and the work piece contact length and the contact duration were short, reduced the knife edge and the work piece heat conduction, has avoided when the traditional processing met everywhere in the cutting tool and the work piece to have the big calorimetry shorting, guaranteed that the cutting tool worked under the temperature not high condition, lengthened cutting tool39。s cutting force is small, has the high stability, but the high quality processes the thin wall ponents. Uses as shown in Figure 2 the lamination down milling the processing method, but highspeed cutting wall thickness , wall high 20mm thin wall
