INVESTIGATION OF MACHINING ON BRASS ROD WITH ALUMINIUM NITRATE INSERT

Abstract

This study presents an experimental investigation on surface roughness of a hardened material (brass) machined by using aluminum nitrate coated insert. The process parameters considered for this experimental work are cutting speed (m/min), Feed (mm/rev) and Depth of cut (mm). By varying these parameters, surface roughness is calculated using surface roughness tester. The experimental results are then optimized using Taguchi analysis-L27 array method. The results revealed that surface roughness was greatly influenced by the feed rate rather than the cutting speed and depth of cut for AlN coated insert.
