Abstract

The customer´s growing demand for higher quality products has forced manufacturing industry to continuously progress in quality control and machining technologies. One of the fundamental metal cutting processes is milling. The aim of this study is to investigate optimum cutting parameters of AlMgSi alloy (EN-AW 6060), which is one of the most commonly used aluminium alloys, using uncoated cemented carbide end mills. The influence of tool geometry (helix angle) and cutting conditions (cutting velocity, and feed rate) on the surface finish produced during high speed milling of aluminium alloy have been investigated. The significance of the parameters on surface roughness has been established with analysis of variance (ANOVA). The cutting parameters regarding surface roughness performance indexes are analysed, and the findings are discussed and evaluated.
