The investigations were carried out by milling of 41Cr4 alloy steel using disc cutter mill with F40M sintered carbide inserts with the anti-wear coating. The investigations were conducted with the dry cutting manner. During the investigations three cutting speeds and three feed speeds were applied, with a constant depth of cut. In the course of the investigations, the temperature in the machining, the zone was recorded using the Flir SC6000HS infrared camera. As a result of the measurements, the mean temperature in the defined measurement zone was determined, and, based on that, a procedure for the determination of the t sub W-max maximum temperature in the workpiece being machined has been proposed. Finally, on the basis of the obtained results, it has been found that the increase in cutting speed leads to the increase in the t sub W-max maximum temperature, whereas the increase in feed speed leads to the reduction of that temperature in the workpiece being machinedGlavni cilj raziskave je razdelava metodologije za vrednotenje vpliva rezalnih parametrov na temperaturo obdelovancev med postopkom rezkanja, ki bi jo bilo mogoče uporabljati tudi v proizvodnih obratih. Vse večja pričakovanja glede produktivnosti in učinkovitosti so privedla do tega, da nastaja v rezalnih procesih tudi vse več toplote. Če naj bodo končni izdelki v zahtevanih dimenzijah, je zaradi intenzivnega segrevanja nujno hlajenje in mazanje. Ustvarjena toplota ne vpliva le na trajnost rezalnih orodij, temveč tudi na lastnosti površinskega sloja obdelovanca.
