Abstract: In the paper is shown a theoretical study regarding the manner in which the quantity of heat that result during grinding process is transmitted to the technological elements and the influence of thermal deformations on the dimensional accuracy of workpieces.
Also, are distinguished experimental data regarding the influence of cutting speed on the temperature in machining zone in the case of different cutting processes.
