Notes

[1] Non-traditional manufacturing processes is defined as a group of processes that remove excess material by various techniques involving mechanical, thermal, electrical or chemical energy or combinations of these energies but do not use a sharp cutting tools as it needs to be used for traditional manufacturing processes.

句意：特种加工是指这样一组加工工艺，它们通过各种涉及机械能、热能、电能、化学能或及其组合形式的技术，而不使用传统加工所必需的尖锐刀具来去除工件表面的多余材料。

[2] The main attraction of EDM over traditional machining processes such as metal cutting using different tools and grinding is that this technique utilizes thermoelectric process to erode undesired materials from the workpiece by a series of rapidly recurring discrete electrical sparks between workpiece and electrode.

句意：相比于利用不同刀具进行金属切削和磨削的常规加工，电火花加工更为吸引人之处在于它利用工件和电极间的一系列快速重复产生的（脉冲）离散电火花所产生的热电作用，从工件表面通过电腐蚀去除多余的材料。

[3] The chemical machining method is widely used to produce micro-components for various industrial applications such as microelectromechanical systems (MEMS) and semiconductor industries.

句意：化学加工广泛用于为多种工业应用（如微机电系统和半导体行业）制造微型零件。

[4] This process is generally used to machine complex cavities and shapes in high-strength materials, particularly in the aerospace industry for the mass production of turbine blades, jet-engine parts, and nozzles, as well as in the automotive (engines castings and gears) and medical industries.

句意：这个加工过程一般用于在高强度材料上加工复杂型腔和形状，特别是在航空业中如涡轮机叶片、喷气发动机零件和喷嘴，以及在汽车业（发动机铸件和齿轮）和医疗卫生业中。

[5] Being a non-mechanical metal removal process, ECM is capable of machining any electrically conductive material with high stock removal rates regardless of their mechanical properties.

句意：作为一种非机械式金属去除加工方法，ECM可以以高切削量加工任何导电材料，而无须考虑材料的机械性能。

[6] LASER is an acronym for Light Amplification by Stimulated Emission of Radiation. Although the laser is used as a light amplifier in some applications, its principal use is as an optical oscillator or transducer for converting electrical energy into a highly collimated beam of optical radiation.

句意：LASER是英文Light Amplification by Stimulated Emission of Radiation各单词头一个字母所组成的缩写词。意思是“通过受激发射光放大”或“光的受激发射”，简称激光。虽然激光在某些应用场合可用来作为放大器，但它的主要用途是光激射振荡器，或者是作为将电能转变为具有高度准直性光束的换能器。

[7] Laser machining is localized, non-contact machining and is almost reacting-force free.

句意：激光加工可以实现局部的非接触加工，因此对加工件几乎没有作用力。

[8] HHHeat Affected ZoneHH (HAZ) in laser machining is relatively narrow and the re-solidified layer is of micron dimensions.

句意：激光加工中的热影响区相对较窄，其重凝固层厚度只有几个微米。

[9] The sonotrode is a piece of metal or tool that is exposed to ultrasonic vibration, and then gives this vibratory energy in an element to excite the abrasive grains in the slurry.

句意：音极是暴露在超声波振动中的一小块金属或工具，它将振动能传给某个元件，从而激励浆料中的磨粒。
