Modeling of temperature and force processes during milling of chromium-nickel alloys by tools with wear-resistant coatings

Abstract

The results of experimental researches of wear resistance, temperature and cutting force components and also imitating modeling of temperature and stress-strain state of a cutting wedge of end milling carbide cutters with different wear-resistant coatings at milling of heat-resistant chromium-nickel alloys are presented. The suggested methodology of the field experiments and the methodology of the temperature-for-forcing conditions simulation taking into account their specific physical-mechanical and thermophysical parameters allow to predict effectiveness of the developed wear-resistant coatings application as from the view of increasing their wear resistance; providing favorable temperature-forcing conditions and correspondingly improving the quality indicators of the machined surface.
