    Electrochemical Discharge Machining: Trends and Development
    (Elsevier, 2021) Akar, S.; Perveen, A.; 315516; 06.06. Makine Mühendisliği; 06. Mühendislik Fakültesi; 01. Çankaya Üniversitesi
    The fabrication of microscale products revolutionizes the way manufacturing industries work today and has become the demand of current era due to their applications in various fields like microfluidics, biomedical testing systems, and microelectromechanical systems. Current research interest of manufacturing industries has shifted toward micromanufacturing process development. Electrochemical discharge machining (ECDM) is one of such recently developed process well known for its capability to machine both conductive as well as nonconductive materials. This process evolved from combination of electrodischarge machining and electrochemical machining. This hybrid machining process becomes an attractive technology due to its process simplicity and application in fabrication of microscale features and three-dimensional structures. This chapter will be focusing on the state-of-the-art review of the ECDM processes and its recent development. Various form of this process such as ECDM turning, ECMD-milling, and ECDM grinding will be presented in this chapter. Based on the research found in the literature, limitation associated with ECDM process will be demonstrated, and future research trend for overcoming these drawbacks will be narrated. © 2021 Elsevier Inc.

    Surface Modification Through Micro-EDM Process
    (Apple Academic Press, 2024) Perveen, A.; Akar, S.; 06.06. Makine Mühendisliği; 06. Mühendislik Fakültesi; 01. Çankaya Üniversitesi
    Electro-discharge machining, among other nonconventional machining processes, is known for its capability to machine materials regardless of hardness. In addition toits contactless and zero-force nature of machining, this process is reported to contribute to surface alteration and modification. Literature reveals surface modification through powder mixed EDM; modification through electrode materials, modification through electrical discharge (ED) coating process as some of the imperative surface modificationtechniques that can alter surface microstructure and therefore, enhances its properties such as microhardness, surface finish, wear, and corrosion resistance. This chapter will present a comprehensive discussion on these surface modification practices implemented to improve the functional characteristics of the surface machined by micro-EDM. © 2024 by Apple Academic Press, Inc.
