description: This study is devoted to the evaluation of machined surface roughness and average cutting temperature during finishing longitudinal turning of workpieces made of heatresistant high-alloy steel 10GN2NMFA without the use of cooling with T15K6 carbide plates. It was experimentally established that the dependence of the average temperature on the machining speed in the investigated range of cutting modes has an extreme character for each value of feed, and the values of the average roughness Ra during machining with sharpened tools were in the range of Ra 0.8-1.25 microns, which corresponds to the 7th class of roughness. In the course of evolutionary transformations in the cutting system, the smallest change in surface microrelief for each feed value was recorded at speeds characterized by minimum cutting temperatures. The average roughness by the end of the period of durability of inserts in all cases was within Ra 1.8-2.5 microns. Thus, at dry finishing of workpieces from heat-resistant steel 10GN2NMFA with surface roughness of 6 class the full resource of inserts up to critical wear can be used, for surfaces of 7 class of roughness the time of operation of inserts is reduced to 40-60% of the durability period. In this case, a turning surface of a given quality can be obtained without the use of additional finishing passes and operations.
