Abstract

The electrical discharge machining process is useful to manufacture complex shaped parts with high accuracy; however, it has unfriendly environmental impacts such as toxic emissions and health hazards; these impacts do not align with the recent orientation toward green industrial environments. Nowadays, researchers, practitioners, and designers focus on implementing sustainable EDM-based green environmental principles. Thus, this article presents an extensive overview of most of the enhancement and eco-friendly technologies for improving the efficiency of the EDM process (material removal rate, lower electrode wear ratio, and surface roughness) and lowering the environmental impacts. These enhancement technologies have been classified into four drivers. The advantages and limitations of each technology have been discussed. Then, the maturity of each technology has been estimated through technology readiness levels.

摘要

放电加工工艺可用于制造高精度的复杂形状零件；然而，它具有不利的环境影响，例如有毒物质排放和健康危害；这些影响与最近对绿色工业环境的定位不一致。如今，研究人员、从业者和设计师专注于实施可持续的基于 EDM 的绿色环境原则。因此，本文广泛概述了大多数用于提高 EDM 工艺效率（材料去除率、较低的电极磨损率和表面粗糙度）和降低环境影响的增强和环保技术。这些增强技术被分为四个驱动因素。讨论了每种技术的优点和局限性。然后，
