1、附录附录 1英文原文：High-speed cutting processing in mold manufacture applicationA.J.G. Nuttall *, G. LodewijksAbstractThe 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
2、 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 molds size, the shape and the surface roughness
3、, 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 crafts contrast, elaborated the high-speed cutting processing superiority. In the article a

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 prod

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 fo

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 wi

9、 quantitiess, 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 technologyA
10、s 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
11、, 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 i

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 av
