Optimization of cutting parameters to improve power consumption and material removal rate in high efficiency milling

Abstract

This study is an attempt to obtain a suitable combination of the milling parameters to optimize electrical power and material removal rate (MRR) in slot milling of aluminium 6061. Machining parameters of radial depth of cut (RDOC), feedrate (Fr) and axial depth of cut (ADOC) are optimized using high efficiency milling cutting strategy. The results are analyzed through response surface and ANOVA for power and MRR. Response surface optimization shows that the optimized results are RDOC=48.8 mm, Fr=3000 mm/min, ADOC=6mm. The error between the predicted and the confirmation results is 4.3%.
