Special Issue Information
Dear Colleagues,
Ultra-precision machining (UPM) is an indispensable technology for manufacturing high-performance components with sub-micrometric form accuracy and nanometric surface integrity. To date, the UPM technology has been widely employed in various important engineering areas such as semiconductors, optics, biomedicine, and aerospace. However, UPM still faces persistent challenges when machining difficult-to-machine materials, e.g., high-strength alloys, ceramics, and composites. The intrinsic properties of these materials lead to significant barriers, e.g., high cutting forces from excessive plastic deformation in ductile alloys, brittle fracture causing severe surface and subsurface damage in ceramics, and inconsistent surface finishes in heterogeneous composites. The poor machinability impedes the wider adoption of these advanced materials. This Special Issue, “Innovative Processes and Theoretical Advances in Ultra-Precision Machining”, addresses these scientific frontiers by spotlighting novel research that overcomes conventional UPM limitations. We invite contributions of original research and reviews that explore process innovations, theoretical advances, and mechanistic breakthroughs to enhance the machinability of difficult-to-machine materials in UPM. Research areas may include (but are not limited to) the following:
- Advanced UPM processes: ultra-precision cutting/turning/milling/grinding/polishing/hybrid approaches.
- Micro-/nano-machining: mechanical, energy-beam, and electrochemical processes.
- Field-assisted techniques: magnetic/electric/laser/vibration/thermal/hybrid-field-enhanced machining.
- Surface engineering: surface modifications (e.g., ion implantation) and surface effects (e.g., mechanochemical effect) for ultra-precision machining.
- Material design: microstructure and mechanical property regulation for ultra-precision machining.
- Theoretical advances: multi-scale modeling (e.g., MD/CPFEM/FEM/Analytical model), and micro-/nano-scale material removal mechanisms.
- Characterization innovations: in situ/ex situ analysis of machined surface/subsurface integrity, and micro-/nano-mechanical testing.
- Post-processing for additive manufacturing: ultra-precision machining for finishing of additively manufactured components.
- Difficult-to-machine materials: metals/alloys, ceramics, and composites.
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 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. Machines 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 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.
