A Cutting Parameter Energy-saving Optimization Method for CNC Turning Batch Processing Considering Tool Wear

In a CNC batch turning process, the increased tool wear will lead to a significant raise of energy consumption. Due to the lack of researches on synergistic effect of tool wear and cutting parameters on energy consumption, this paper proposes an energy aware cutting parameter optimization approach for CNC batch turning by considering tool wear. Firstly, the synergistic mechanism of tool wear and cutting parameters on energy consumption of CNC batch turning is analyzed. On the basis, a multi-objective optimization model for minimizing energy consumption and production time is established with the variables of the cutting parameters under different tool wear conditions. Then a multi-objective simulated annealing algorithm is proposed to solve the optimization model. Compared with the empirical cutting parameters, the total energy consumption can be reduced by 14.9% and the total production time can be reduced by 9.8% with the optimized cutting parameters. This verifies the effectiveness and practicability of th
