Recent Developments in Electrical Discharge Machining Technology

Dear Colleagues,

Electrical discharge machining (EDM) is a non-traditional manufacturing process that has revolutionized the precision engineering industry. Over the years, EDM has evolved significantly, with advancements in control systems, development of newer pulse generators, electrode materials, and dielectric fluids, leading to enhanced precision, efficiency, and versatility. EDM offers several advantages over traditional machining processes, including high precision, complex geometries, minimal tool wear, and versatility. Despite these advantages, EDM also faces challenges such as high energy consumption, longer machining times, matte surface finish, heat-affected zones, and the need for specialized equipment and skilled operators.

Research in this area is crucial for addressing these challenges and further enhancing the capabilities of EDM. This includes developing more efficient EDM processes, optimizing electrode materials, dielectrics, and part geometries, and exploring hybrid machining techniques that combine EDM with other manufacturing processes.

The goal of this Special Issue is to comprehend significant studies and recent advances in the areas of multiscale EDM and EDM-based hybrid machining processes. Experimental investigation, analytical modelling, and numerical simulations in the areas of EDM and EDM-based hybrid processes are of interest.

We look forward to receiving your contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Micromachines is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
