Optimization of CNC Machining Parameters in Turning En 9 Steel Using Taguchi Method

Surface roughness is the significant important parameter in conventional machining. Optimizing this parameter is most challenging task in turning process. Industries are working more on reducing the rejection rate and improving the surface roughness. Better quality of the product can afford finest customer satisfaction. There is a neck to neck competition in the trade market which requires highly quality products at the lowest cost. The transformation of raw materials into finished goods result various kinds of products. Surface roughness says about the quality of machining and also about the quality of product. The materials which have good surface finish posses better property as compared to lower surface finish of that material .Industries across the world are struggling to overcome the problem of rejection rate. By reducing rejection rate and optimally utilization of machines and their working conditions, we can not only be able to produce good products but can also reduce the cost significantly. Industries are in need of working skills of machine tool operator for the selection of best cutting conditions. This helps not only in producing the product with less rejection rate, but also help in reducing the cost of the product.
