Optimization of Sustainable Carbon Steel Turning Parameters

The purpose of the present research is to discover optimum cutting parameters for sustainable machining using a turning machine to improve machining performance for higher productivity and quality of the product. In this research, experimental and theoretical work was carried out. The experimental work includes machining of a shaft from carbon steel (AISI 1045) using turning machine, surface roughness measurement, and cutting temperature measurement. Theoretical studies develop empirical equations for surface roughness and cutting temperatures. In order to reduce cutting temperatures and achieve smooth surfaces, these equations are intended to be utilized in the Lagrange optimization approach. At low cutting temperature and smooth surface, the conditions of sustainable cutting will be achieved. The optimal cutting speed and feed rate parameters obtained by applied Lagrange optimization technique were cutting speed 1000 rpm and feed rate 1.8 mm/rev.
