摘要

Purpose: The physical and mathematical description of tools wear during technological process and need to the enlarge tool life require knowledge of material data, e.g. density, specific heat and coefficient of thermal conductivity. A formation of heat during tool work and increase of cutting edge temperature are results of friction between tool and stock. The distribution of temperature in cutting edge material during machining can be defined in selected places with the use of thermocouple. The measurement of arisen heat during machining is determined by analytic way as a measured temperature distribution and the thermal properties of cutting edge and work piece, which are known. The knowledge of temperature distribution and thermal flux process, which accompanies to, is the one of the factors influencing on reach the conclusions in relation to describe wear and suggestion to increase tool life. Design/methodology/approach: The results of investigations of the temperature field in cutter edge of cutters made of HS 3-1-1,5 and HS 6-5-2 low-alloyed high speed steel and the coefficient of thermal conductivity of listed kinds of steels to determinate their effective use on cutting tools were described. Findings: Decreasing of contents of alloy addition did not significantly affect the thermal and physical properties changes of SW3S2 steel. Research limitations/implications: To ensure applicable quality requirements during production of tools made of low-alloyed high-speed steels, it is very important so that their cutting ability will not be lower than analogical tools made of classic high-speed steels. It requires establishing such good work conditions in case to be competed effectively with classic high-speed steels. Practical implications: The obtained results of investigation showed, that decreasing contents of alloy addition did not affect the thermal and physical properties changes of HS 3-1-1,5 steel. Originality/value: The carried out investigation showed, that the cause of lower durability of cutters should be sought in lower temperability of HS 3-1-1,5 low-alloyed high-speed steel.
