摘要

In the present study, the performance of cutting tool significantly improved in cryogenic treatment, this was achieved through the enhancement in mechanical and tribological properties of tool materials. This effect was attained in the treatment of the tool material at about − 190 °C temperature. After that, the tempering and machining experiments were conducted under the different operating conditions. The parameters involved in the cutting process viz. speed, feed rate and depth of cut were optimized using Taguchi optimization on an L9 orthogonal array. The results showed that the cryogenic treatment improves tool hardness, wear resistance and overall performance of the process. In addition, a reduction of approximately 23–25% was observed in cutting force under the optimum conditions. It also helps to identify that cryogenic treatment is an effective way to increasing the tool life and efficiency of the process is planned with titanium alloys.
