Abstract :
A methodology based on high speed cutting experimental test and observational methods for analyzing wear course of coated tool in milling cast iron and quenched and tempered 45 steel by coated cemented carbide inserts is introduced. The applied coatings were TiCN and TiAlN films. The geometrical model of coated tool abrasion is offered and analyzed all possible abrasion morphology of coating. Stress distributed state graph and curve of temperature versus distance from cutting edge were obtained for analysis of coated tool wear mechanism. The milling investigations were conducted at various cutting speeds and feed rates. Through analysis about the impact of cutting speed and feed on roughness, a sufficient correlation of coatings´ impact resistance at various temperatures with their cutting performance at corresponding cutting speeds and feeds was revealed.
