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.
