This paper presents the results of experimental work carried out in dry turning
operation of nitrogen alloyed duplex stainless steel ASTM A 995 Grade 5A. In this
investigation, the cutting parameters considered were cutting speed, feed rate and depth of
cut. The effects of these cutting parameters on the surface roughness were analyzed using
Taguchi technique. The results revealed that the feed rate is the most important parameter
affecting the surface roughness, followed by cutting speed and depth of cut. The minimum
surface roughness was obtained when the process parameters were set at their optimum
values.
