This paper presents complete process of turning operation by using CNC machine tool and the input parameters associated with the process that can be controlled to enhance the output quality parameters like material removal rate and average surface roughness as per the desired requirement. Every detail of turning operation and associated parameters is explained. The optimization techniques like Taguchi, Anova, S/N ratio, grey relational analysis is also described and their importance is also discussed in detail. The study explains step by step procedure involved in optimization of turning process in detail.

Checking whether process and product are satisfying or functioning according to the technical specification is not enough to assure competitiveness. Competition compels organizations to develop efforts to assure that product and process characteristics are on target values and the variability around those targets is minimal. This article proposes an alternative method for optimizing both the mean and standard deviation of a quality characteristic of the process or product. The objective function accommodates all the response types, allowing the practitioner to assign distinct weights to process mean and standard deviation and to find trade-off solutions between them, taking their relative magnitudes into account. Two classical examples from the literature are used to illustrate the feasibility of the proposed method and compare its results with those of other popular methods. A practical procedure for implementing the proposed method is also presented.
