Experimental and Numerical Investigation of Tool Life of Single Point Cutting Tool during Turning Process


The heat generated at the tool-chip interface dissipates the heat into the tool, which causes the rise in temperature at the tool tip during the metal cutting process. The temperature rise in cutting tool tends to soften it and causes loss of tool material in the cutting edge leading to its failure. Objective: To determine the temperature distribution along the tool tip for different cutting parameters like feed rate, cutting speed and depth of cuts. Method: In this study, tool chip interface temperature was determined in cutting of mild steel workpiece with HSS as the cutting tool. The effects of different parameters like cutting speed, feed rate and depth of cut are taken into account so as to predict their effects on tool life are studied both in experimental and numerical analysis. Finding: In present work the tool life of HSS tool is evaluated at different cutting parameters during turning process. It has been found that the tool life is decreases with feed rate and cutting speed. The optimal process parameters found in turning process are high cutting speed, low depth of cut and lower feed rate. Conclusion: The results have shown that change in cutting speed and feed rate has the maximum effect on cutting temperature than depth of cut.
