摘要：

This paper presents the results of investigations of temperature field distribution in the cutting edge and yield strength of tool material for low-alloy high-speed steels. Investigations of temperature distribution in cutting edges were made during C60 steel turning using a semi-natural constantan thermo-element. The obtained results show that the decrease in addition alloy content does not influence the change in thermal-physical properties of low alloy high-speed steels. Investigations of the durability of cutting edges confirm that to define working conditions of the tool made of high-speed steel, resistance against hardness loss with increasing temperature at temperatures higher and lower than tempering temperature is the most significant. The results of durability investigations of cutters made of HS3-1-2 steel with various kinds of surface treatment confirm the reasons for cutting edge wear of tools made of high-speed steel and ways of the increasing their durability.
