The influence of the tool base on the formation of stresses in wear-resistant coatings in the cutting process

Abstract

The results of studies of the influence of the material of the tool base on the formation of stresses in wear-resistant coatings of various compositions are presented. It is shown that the stresses in the coating during the cutting process depend on the properties of the material of the tool base and the composition of the coatings. The stresses change in the coatings during the cutting process is analyzed. It is shown that the use of coatings with high compressive stresses makes it possible to increase the period of resistance of plates made of hard alloy and high-speed steel.
