Surface temperature control is vital to avoid this kind of damage. Difficulties in empirical measurement of surface temperatures in-process imply the measurement in points other than the ground surface. Indirect estimation of temperatures demands the use of thermal models. Among the numerous temperature measuring techniques, infra-red measurement devices excel for their speed and accurate measurements. With all of this in mind, the current work presents a novel temperature estimation system, capable of accurate measurements below the surface as well as correct interpretation and estimation of temperatures. The estimation system was validated by using a series of tests in different grinding conditions that confirm the hypotheses of the error made when measuring temperatures in the workpiece below the surface in grinding. This method provides a flexible and precise way of estimating surface temperatures in grinding processes and has shown to reduce measurement error by up to 60%.<\/jats:p>","DOI":"10.3390\/s18124134","type":"journal-article","created":{"date-parts":[[2018,11,26]],"date-time":"2018-11-26T03:24:27Z","timestamp":1543202667000},"page":"4134","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["On the Influence of Infra-Red Sensor in the Accurate Estimation of Grinding Temperatures"],"prefix":"10.3390","volume":"18","author":[{"given":"Lander","family":"Urgoiti","sequence":"first","affiliation":[{"name":"IK4-IDEKO Research Alliance, Arriaga Kalea, 2, 20870 Elgoibar, Spain"},{"name":"Mechanical Engineering Department, Universidad del Pa\u00eds Vasco (UPV\/EHU), Paseo Rafael Moreno \u201cPitxitxi\u201d, 3, 48013 Bilbao, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Barrenetxea","sequence":"additional","affiliation":[{"name":"IK4-IDEKO Research Alliance, Arriaga Kalea, 2, 20870 Elgoibar, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jose Antonio","family":"S\u00e1nchez","sequence":"additional","affiliation":[{"name":"Mechanical Engineering Department, Universidad del Pa\u00eds Vasco (UPV\/EHU), Paseo Rafael Moreno \u201cPitxitxi\u201d, 3, 48013 Bilbao, Spain"},{"name":"Aeronautics Advanced Manufacturing Center (CFAA), University of the Basque Country (UPV\/EHU), 48170 Zamudio, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"I\u00f1igo","family":"Pombo","sequence":"additional","affiliation":[{"name":"Mechanical Engineering Department, Universidad del Pa\u00eds Vasco (UPV\/EHU), Paseo Rafael Moreno \u201cPitxitxi\u201d, 3, 48013 Bilbao, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jorge","family":"\u00c1lvarez","sequence":"additional","affiliation":[{"name":"IK4-IDEKO Research Alliance, Arriaga Kalea, 2, 20870 Elgoibar, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,11,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"581","DOI":"10.1016\/j.cirp.2015.05.004","article-title":"Abrasive machining of advanced aerospace alloys and composites","volume":"64","author":"Klocke","year":"2015","journal-title":"CIRP Ann."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"337","DOI":"10.1016\/j.cirp.2018.04.093","article-title":"Increased productivity in centerless grinding using inertial active dampers","volume":"67","author":"Barrenetxea","year":"2018","journal-title":"CIRP Ann."},{"key":"ref_3","doi-asserted-by":"crossref","unstructured":"Vidal, G., Ortega, N., Bravo, H., Dubar, M., and Gonz\u00e1lez, H.
