Identification of the Impact of Tool Protective Coatings on Temperature and Heat Distribution in the Cutting Zone

Dear Colleagues,

Machining is still the basic technique for manufacturing machine parts. Most of the tools used in the engineering industry are coated tools. The main task of using protective coatings is to reduce tool wear. Protective coatings primarily change the tribological interactions at the interface between the cutting tool and the workpiece. They also affect the amount of heat generated during cutting, and above all, the change in heat flows flowing from the decohesion zone of the material to the blade, to the chip and to the workpiece. High temperature in cutting is an unfavorable phenomenon because it promotes wear of the blade. Recently, the machine parts industry has been striving to miniaturize the manufactured elements, to create products with a complex shape and to use materials that are difficult to machine. Tools are being used more and more often in harsh conditions. Therefore, knowledge of the mechanisms of the impact of coatings on the cutting process, and especially on the amount of heat generated and its distribution in the cutting zone, is so important.

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. Materials 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 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.
