Increasing the Efficiency of Laser Heat Treatment of a Lathe Tool with Allowance for the Influence of the Cutting Regimes

A complex approach to estimation of the process of cutting with a hardened tool is proposed. The choice of factors having the strongest influence on the durability value of cutting tools upon their laser treatment has been made and the significant influence of their interaction effects has been established. An adequate mathematical model of the cutting process has been constructed. It is shown that to achieve the greatest positive effect, irradiation of cutting tools should be carried out taking into account their particular operating conditions. It is recommended to use this model under working conditions to obtain the required durability of the tool under given operating conditions.
