Special Issue Information
Dear Colleagues,
The grinding process dates from the prehistoric man, where it was employed to provide a desired shape and sharpen his tools, as well as to produce artifacts by rubbing them on a slab of gritty rocks, such as sandstone. Since then, the importance of grinding has increased significantly, and humanity has become more dependent on grinding because many components from several industries, such as metal working, cutlery, electrical, microelectronic, automotive, aerospace, oil, and railway, among others, have some requirements that could be achieved by grinding as a first option. In other words, grinding aims to achieve a combination of tight dimensional tolerances and low surface roughness (Ra parameters) to uncountable type of parts. However, grinding is a peculiar process when compared to machining with single edge tools. Cutting is performed by the action of thousands of hard abrasive particles with undefined geometry and randomly distributed throughout the wheel volume. Additionally, grinding wheels work at a high cutting speed, and the radial depth of the cut is generally on a micrometric scale. The presence of cutting fluid is quite indispensable in grinding because of the great amount of heat that is generated in the grinding zone as a result of numerous grit edges in contact with the workpiece.
Compensating for the increase in the material removal rate with low temperatures in the grinding zone, in order to reduce the portion of heat that is transferred to the workpiece during grinding and avoid the occurrence of thermal damage to the workpiece, is perhaps the biggest challenge today.
All these peculiarities make grinding even more attractive for researchers and machining users from many industries, thereby representing opportunities for new research topics.
This Special Issue aims to address the latest research in grinding metals and alloys, which can really bring contributions to academics, engineers, and machining professionals from various industries.

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. Metals 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 2600 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.
