。電火花加工是利用存儲在電容器組中的電能（一般為50V/10A量級）在工具電極（陰極）和工件電極（陽極）之間的微小間隙間進行放電來去除材料的。該工藝是最古老的特種加工工藝，主要用于凹腔和輪廓加工，以及從具有高的比剛度的零件表面去除余料。10%左右。最近，還將電化學加工應用于電子工業(yè)的微加工中。泵壓后的電解液以高達5～50 m/s的速度通過間隙，將溶解后的材料、氣體和熱量帶走。由激光發(fā)射出的光能具有不同于其他光源的特點：光譜純度好、方向性好及具有高的聚焦功率密度?？梢跃_控制材料去除率使得激光加工成為微制造和微電子技術(shù)中非常重要的加工方法。激光打孔可以加工用其他方法難以加工的高深徑比的孔。在超聲加工中，實際切削由液體中的懸浮磨粒或者旋轉(zhuǎn)的電鍍金剛石工具來完成。換能器將電脈沖轉(zhuǎn)換成垂直沖程，垂直沖程再傳給變幅桿進行放大或壓抑。 the workpiece is too flexible or slender。10% of the material thickness can be maintained in chemical order to improve the production rate, the bulk of the workpiece should be shaped by other processes(such as by machining)prior to chemical variations can occur because of size changes in workpiece due to humidity and variation can be minimized by properly selecting etchants and controlling the environment in the part generation and the production area in the Machining(ECM)Electrochemical metal removal is one of the more useful nontraditional machining the application of electrolytic machining as a metalworking tool is relatively new, the basic principles are based on Faraday , electrochemical machining can be used to remove electrically conductive workpiece material through anodic mechanical or thermal energy is process is generally used to machine plex cavities and shapes in highstrength materials, particularly in the aerospace industry for the mass production of turbine blades, jetengine parts, and nozzles, as well as in the automotive(engines castings and gears)and medical recent applications of ECM include micromachining for the electronics machining(ECM), shown in , is a metalremoval process based on the principle of reverse this process, particles travel from the anodic material(workpiece)toward the cathodic material(machining tool).Metal removal is effected by a suitably shaped tool electrode, and the parts thus produced have the specified shape, dimensions, and surface forming is carried out so that the shape of the tool electrode is transferred onto, or duplicated in, the cavity produced is the female mating image of the tool high accuracy in shape duplication and high rates of metal removal, the process is operated at very high current densities of the order 10100 A/cm2,at relative low voltage usually from 8 to 30 V, while maintaining a very narrow machining gap(of the order of mm)by feeding the tool electrode with a feed rate from to 20 mm/ material, gas, and heat are removed from the narrow machining gap by the flow of electrolyte pumped through the gap at a high velocity(550 m/s), so the current of electrolyte fluid carries away the deplated material before it has a chance to reach the machining a nonmechanical metal removal process, ECM is capable of machining any electrically conductive material with high stock removal rates regardless of their mechanical particular, removal rate in ECM is independent of the hardness, toughness and other properties of the material being use of ECM is most warranted in the manufacturing of plexshaped parts from materials that lend themselves poorly to machining by other, above all mechanical is no need to use a tool made of a harder material than the workpiece, and there is pra
