The tools used in machining have been developed over the years to improve their performance, by reducing the cutting forces, the friction coefficient, and the heat generated during the cutting process. Several cooling systems have emerged as an effective way to remove the excessive heat generated from the chip-tool contact region. In recent years, the introduction of nano and micro-textures on the surface of tools has allowed to further improve their overall performance. However, there is not sufficient scientific data to clearly show how surface texturing can contribute to the reduction of tool temperature and identify its mechanisms. Therefore, this work proposes an experimental setup to study the tool surface characteristics\u2019 impact on the heat transfer rate from the tools\u2019 surface to the cooling fluid. Firstly, a numerical model is developed to mimic the heat energy flow from the tool. Next, the design variables were adjusted to get a linear system response and to achieve a fast steady-state thermal condition. Finally, the experimental device was implemented based on the optimized numerical model. A good agreement was obtained between the experimental tests and numerical simulations, validating the concept and the implementation of the experimental setup. A square grid pattern of 100 \u03bcm \u00d7 100 \u03bcm with grooves depths of 50, 100, and 150 \u03bcm was introduced on cutting insert surfaces by laser ablation. The experimental results show that there is a linear increase in heat transfer rate with the depth of the grooves relatively to a standard surface, with an increase of 3.77% for the depth of 150 \u03bcm. This is associated with the increase of the contact area with the coolant, the generation of greater fluid turbulence near the surface, and the enhancement of the surface wettability.<\/jats:p>","DOI":"10.3390\/app12136583","type":"journal-article","created":{"date-parts":[[2022,6,29]],"date-time":"2022-06-29T20:47:56Z","timestamp":1656535676000},"page":"6583","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Influence of Micro-Textures on Cutting Insert Heat Dissipation"],"prefix":"10.3390","volume":"12","author":[{"given":"Jos\u00e9","family":"Rosas","sequence":"first","affiliation":[{"name":"Centre for Research & Development in Mechanical Engineering-Department of Mechanics (CIDEM-DEM\/ISEP), School of Engineering, Polytechnic Institute of Porto, Rua Dr. Roberto Frias, 712, 4200-465 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9344-8503","authenticated-orcid":false,"given":"Hernani","family":"Lopes","sequence":"additional","affiliation":[{"name":"Centre for Research & Development in Mechanical Engineering-Department of Mechanics (CIDEM-DEM\/ISEP), School of Engineering, Polytechnic Institute of Porto, Rua Dr. Roberto Frias, 712, 4200-465 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7126-6365","authenticated-orcid":false,"given":"Bruno","family":"Guimar\u00e3es","sequence":"additional","affiliation":[{"name":"Center for Microelectromechanical Systems (CMEMS-UMinho), University of Minho, Campus de Azur\u00e9m, 4800-058 Guimar\u00e3es, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2834-0501","authenticated-orcid":false,"given":"Paulo A.
