Integration of process planning and cutting parameter optimization for energy-aware CNC machining

This paper presents an integrated approach of process planning and cutting parameter optimization for energy-aware CNC machining. Firstly, the energy characteristics of machining process are explicitly analyzed by considering multiple process flexibilities and the cutting parameters. Then a multi-objective integration model is proposed to achieve minimum energy consumption and balance of machine workloads, which is solved based by a Multi-objective Simulated Annealing algorithm. Finally, a case study is presented to demonstrate the performance of the proposed multi-objective integration problem.
