An investigation on slab milling operation to find out optimum cutting parameters

Abstract

Milling is a widely used machining operation. For generating a flat wide surface, slab milling is usually employed in industry. In this experimental work, slab milling operation has been performed on low alloy steel to obtain appropriate cutting parameters in order to get low surface roughness, low vibration and high material removal rate. Taguchi method and composite desirability function of response surface methodology have been used to get required cutting parameters. It has been observed from Taguchi’s methodology that surface roughness is affected mostly by variation of cutting velocity or speed; in case of material removal rate, effect of feed is quite high, and speed also has sufficient effect on it.
