Special Issue Information
A recent trend in technology and scientific research is to push further on the miniaturization of devices and components and to produce high-precision parts with severe geometric constraints. The need to fabricate components with such complex geometrical and dimensional characteristics has led to greater attention towards micromanufacturing techniques. Among the various technologies available for micromanufacturing, micro-EDM (electrical discharge machining) is widely used in micro-hole machining because of its high precision and negligible contact stresses. However, there are still some drawbacks related to the use of this technology in microdrilling; in general, high tool wear ratio, low erosion speed, aspect ratio and downsizing limits, geometrical and dimensional constraints are still noteworthy aspects in which improvements are constantly sought. This Special Issue aims to deepen the critical aspects mentioned above and, in particular, will focus on the following topics:
- Influence of the process parameters on both the process and the product performance;
- EDM solutions for achieving holes with very small diameters or high aspect ratios;
- Effect of electrode materials and characteristics on the micro-EDM drilling performance;
- Application of micro-EDM drilling to innovative/advanced materials such as ceramic materials;
- Characterization of micro-holes;
- Use of nonconventional dielectric fluids and powder mixed fluids;
- Integration of EDM and other technologies in micro-EDM drilling;
- Issues concerning the sustainability of the EDM process applied to micro-drilling;
- Theoretical aspects and modelling.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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. Applied Sciences is an international peer-reviewed open access semimonthly 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 2400 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.
