Abstract: FG 250 is flange used in water pump which is machined and finished using VMC. Present work focuses on optimization of drilling process parameters of FG 250 flange using taguchi optimization technique. Surface roughness was the response variable investigated. Experimental results indicate that proposed mathematical model suggested adequately describe performance indicator within the limits of factors that are being investigated. Flow rate is the most influencing factor on surface roughness followed speed and feed.
