Dry Turning of Mild Steel Using HSS Tool: Parametric Effect Evaluation of Material Removal Rate

Sustainable material processing is the current need of machine tool industries. This paper aims to design and experimentally study the material removal rate of mild steel during dry turning using a high-speed steel single point cutting tool and a conventional lathe machine. Twenty-seven turning operations are designed using an orthogonal array experimental design method. The speed, feed and depth of cut are selected as input parameters while material removal rate is considered as quality parameter. Input parameters are varied twenty-seven times during dry turning of mild steel workpieces. Effects of input parameters are investigated to discover which one has a significant effect on material removal rate and hence to determine the dry turning conditions for mild steel. Statistical test results revealed that the depth of cut is significant than feed and speed. The F-value obtained from ANOVA result and Pareto chart are verified that depth of cut is significant on material removal rate of mild steel during dry turning
