Selection of laser processing parameters for hot stamping tools based on mathematical planning of the experiment

Abstract

die steel on operating resistance of working tool of hot-stamping machines, which are designed for hot stamping of roll bearing rings. Thereby development and optimization of laser quenching modes without surface melting on ejec-tors, in order to rise thermal fatigue strength of these roll bearing rings, are the aims of this research. Research, its results and analysis Development of the mathematical model of tool resistance from the effect of laser radiation was conducted via the method of mathematical planning of the experiment, using a full factorial experiment [11]. It was carried out in such way due to insufficient theoretical background of the problems of interaction between laser radiation and tool steels. Ejectors were taken as the subject of this research as the elements of die auxiliaries, which are most susceptible for wear. These ejectors are located in hot-stamping machines for hot stamping of roll bearing rings made of 3Kh3M3F die
