Effect of Coolant and Tool Nose on Material Removal Rate on Conventional Lathe Machine

Abstract

Material removal rate (MRR) is a great challenging field for engineering because it affect the quality and cost of final product. There are many problems comes to origin during material removal process on the conventional lathe machine. In spite of perfect skill and knowledge of operation, we fail to remove material at high accuracy. This paper investigates the effect of different cutting parameter(s) on the Material removal rate. The work piece materials of Mild steel were machined on conventional lathe machine and find the difference between actual and theoretical value. Then we analyze the problems by PDCA method and select two basic parameters “Tool nose and cutting fluid”. After removal of selected problem, the work pieces of same specification were machined on lathe machine and find the result. It was observed that the error of removing material rate decreased up to 42%. We conclude that “Tool nose” increases the cutting forces and “Cutting fluid” increases the thermal stress in the material and hence removal rare increases.
