The paper presents the results of functional parameters of the cutting process using the multilayer coated cutting tool based on nitrides of titanium, zirconium, niobium and aluminum – TiN-TiZrN-TiZrAlN, TiN-TiZrN-TiZrNbAlN before and after the impulse laser processing. It was demonstrated that the impulse laser processing shortens the overall contact length between chips and the front surface, decreases the chips shorting coefficient, cutting force components and the heat flow capacity at the front surface. The shortening of the overall contact length gives some boost to the rate of heat flows along the front and rear surfaces. This fact decreases contact temperatures in comparison with the instrument without the pulsed laser treatment. It was demonstrated that the shortening of the overall contact length between chips and the front surface after the pulsed laser treatment adjusts temperature filed isotherms and stress isobars in the tool cutting wedge to the rear surface and the cutting edge.
