چکیده	The present work focuses on the application of 'Taguchi Approach.' In the cold forging process, die/billet interface plays a significant role. In this work, the influence of varied friction conditions on the barreling is studied. The friction factors of these lubricants molybdenum di-sulphide (m = 0.24), Teflon grease (m = 0.33) and silicon grease (m = 0.4) were obtained from ring compression test (RCT). The whole configuration assumed to be axi-symmetric and the steel solid cylindrical billets compressed between the dies. At each and every incremental level of deformation process, the following results were noted down. From the simulation study mainly barreling depends upon three major factors as friction effect, aspect ratios, and speed of press effect. By using these parameters were optimized to get much uniform distribution of reduce the deformation load and barreling effect.
