Mechanical, Corrosion, and Tribological Properties of Coated Milling Inserts

Abstract

The current study looks at the mechanical, corrosion, and tribological aspects of tungsten carbide milling inserts coated with Aluminum Chromium Nitride (AlCrN) and Diamond-Like Carbone (DLC) in a dry cutting environment. Using the Desirability Analysis, the cutting force (N) and surface roughness (Ra) are considered as output responses, and three different cutting speeds (500, 710, and 1000 rpm), three different feeds (40, 60, 100 mm/min), and depth of cut (0.5, 0.75 and 1 mm). According to ANOVA results, the most effective parameters in multi-objective optimization were feed rate (60.06%), Depth of cut (28.39%), Insert (9.80%), and speed (1.73%). The coated inserts spectra images using a scanning electron microscope SEM/energy dispersive x-ray analysis (EDAX) are also examined. As a result, when compared to other coated milling inserts, DLC inserts performed better in this multi-objective study.
