ABSTRACT

High precision and clos tolerance is an essential requirement of current manufacturing industries dealing in micro-fabrication. The quality of surface obtained after machining process exhibits the utility of product. The various material and alloys are developed continuously to fulfill the need of application in critical conditions. The versatile characteristics of material also required a modification in manufacturing processes. The exotic material required a special treatment of machining to avoid the failure. Various methods of conventional, un-conventional and their hybrids have been developed to meet the above requirement. Wherein, ultrasonic vibration assistance has been extensively applied in numerous manufacturing processes to increase the process performance. In present review, ultrasonic vibration (UV)-assisted manufacturing processes for machining/finishing are covered using selected materials. Additionally, the benefits of UV assistance in welding such as arc compression, plasma pressure are discussed in details. Moreover, assistance of vibration in non-traditional machining processes such as ECM, EDM and AWJM is discussed in detail with their effects. In machining, ultrasonic assistance facilitate basic process by reduction in cutting force, and improvement in the machined morphology. Thus, the outcomes obtained from the large number of published literatures strongly demonstrate the significance of ultrasonic vibration in various sections of present article.

摘要

高精度和紧密公差是当前从事微加工的制造业的基本要求。机械加工后获得的表面质量体现了产品的实用性。不断开发各种材料和合金以满足在临界条件下的应用需求。材料的多功能特性也需要对制造工艺进行修改。这种奇异的材料需要经过特殊的加工处理才能避免失败。已经开发了各种常规、非常规及其混合的方法来满足上述要求。其中，超声振动辅助已广泛应用于众多制造工艺中，以提高工艺性能。在目前的审查中，用于加工/精加工的超声波振动 (UV) 辅助制造工艺使用选定的材料进行覆盖。此外，还详细讨论了紫外线辅助焊接的好处，例如电弧压缩、等离子压力。此外，还详细讨论了非传统加工工艺（如 ECM、EDM 和 AWJM）中的振动辅助及其效果。在加工中，超声波辅助通过降低切削力和改善加工形态来促进基本过程。因此，从大量已发表的文献中获得的结果有力地证明了超声波振动在本文的各个部分中的重要性。等离子压力进行了详细讨论。此外，还详细讨论了非传统加工工艺（如 ECM、EDM 和 AWJM）中的振动辅助及其效果。在加工中，超声波辅助通过降低切削力和改善加工形态来促进基本过程。因此，从大量已发表的文献中获得的结果有力地证明了超声波振动在本文的各个部分中的重要性。等离子压力进行了详细讨论。此外，还详细讨论了非传统加工工艺（如 ECM、EDM 和 AWJM）中的振动辅助及其效果。在加工中，超声波辅助通过降低切削力和改善加工形态来促进基本过程。因此，从大量已发表的文献中获得的结果有力地证明了超声波振动在本文的各个部分中的重要性。
