附录 附录1： 英文原文 Ultraprecisio processing,andultra-high-speed processing technologies ? First, Technical overview Sophisticated, ultra-precision processing is a relative concept but as a general increase in the level of craftsmanship, different divisions have different age limits, but no strict uniform standards. From the current level of mechanical processing technology and ultra precision processing usually processing precision0.3μm ， Surface roughness Ra value0.03μm. Hypervelocity processing technology refers to the cutlery used paint materials through greatly increased cutting speed and chin to improve the material removal rate of speed, accuracy and Processing processing quality modern processing technology. Hypervelocity scope for cutting speed processing different working materials, different ways and different machines. Currently, the general view, ultra high speed machining of the cutting speed range of materials : aluminum alloy over 1600m /min, cast iron for 1500m /min, ultra heat -300m /min nickel alloys, titanium alloys to 150 ～ 1000m /min, fibre reinforced plastics for 2000 ～ 9000m /min. The cutting speed range of alternative processes for Chexue 700 ～ 7000m /min, Xianxiao 300 ～ 6000m /min, drilling 200 ～ 1100m /min, grinding 250m /s above, and so on. Ultra high speed processing technologies include : ultra high speed machining and grinding research mechanisms, hypervelocity main modules manufacturing technology, ultra high speed into the module manufacturing technology, ultra high-speed processing with cutlery and abrasive manufacturing technology, ultra high speed processing online automatic detection and control technologies. Ultra precision processing refers to the current processing components size precision than 0.1μm, the surface roughness Ra 0.025 μm, and the machine tools used in the resolution positioning accuracy and repetitive than 0.01μm processing technology, also known as the Asian micrometres processing technology, and is to nano-clas
