Selection of optimum turning parameters based on cooperative optimization of minimum energy consumption and high surface quality

Energy saving and surface quality are priorities in manufacturing industry with increased sustainability and high-quality consciousness. This paper presents a cooperative optimization approach to choose optimal cutting parameters for energy saving and quality assurance considering the effects of tool wear and cutting parameter combinations at a certain material removal rate. Cutting energy consumption, energy efficiency and surface roughness are optimization objectives and their functions are developed with cutting parameters and tool wear. The multi-objective optimization model is constructed with constraints and solved by NSGA-III. A turning application case is given and the results illustrate the effectiveness of the proposed method.
