Machinability Evaluation of TC11 Titanium Alloy in Finish Hard Turning Based on the Response Surface Methodology
TC11 is an α+β heat resistance titanium alloy with high strength to weight ratio, good corrosion resistance and high service temperature up to 500°C. Response Surface Methodology (RSM) is an empirical statistical modeling technique employed for multiple regression analysis using quantitative data obtained from properly designed experiments to solve multivariable equations simultaneously. In this paper, a series of experiments were carried out to evaluate the machinability of TC11 alloy based on RSM. Optimum results show feed rate at 0.05mm/r, depth of cut at 0.25mm and moderate cutting speed at 110.9m/min giving the satisfied machining quality.
