Hard Turning processes are widely used in the automotive industries, die and mould industries. Hard Turning refers to the process of single point cutting of hardened pieces within the two-micron range with hardness between 58 and 70 HRC. The present study deals with the critical review of optimizing the machining parameters of hard turning process that affects machined accuracy and surface finish. The input parameters as speed, depth of cut, and feed. The review will give a detailed insight of hard turning process which includes methodologies adapted by various researchers and the optimization technique implemented. The research gap is also included in the present study to carry the futuristic research work.
