Abstract: To research the complex interaction between energy efficiency of machine tool and process parameters,an optimization method of NC milling parameters for energy efficiency based on Taguchi method and Response Surface Method (RSM) was proposed.To establish the function of energy efficiency,characteristics of energy consumption in a milling process were analyzed.After conducting an optimized experiment based on Taguchi Method,fitting equations of specific energy and processing time were founded based on RSM.Thus a multi-objective optimization model was established,which took NC milling parameters as the variables,high production efficiency and high energy efficiency in processing time as the optimization objectives.Multi-objective particle swarm optimization algorithm was used to solve the model,and the relationship between process paramcters and specific energy or processing time was analyzed through the experimental data and the results of the optimization.

Key words: Taguchi method, response surface method, numerical control milling, process parameters, energy efficiency
