To overcome the difficulties in previous researches about energy-efficient design of parts, a method to estimate machining-related energy consumption of parts at the design phase is proposed. The binary tree is constructed to describe the structure of a part, and each node in the binary tree represents one feature in the part. The material embodied energy, theoretical cutting energy consumption and air-cutting energy consumption of a feature can be calculated based on its design and manufacturing parameters. At the design phase, manufacturing parameters of a feature can be obtained by the method of feature mapping from design parameters. By adding up above three types of energy consumption, total energy consumption of a feature can be calculated. Further, by adding up total energy consumption of all features in a part, the energy consumption of this part can be estimated. The proposed method was demonstrated by estimating the energy consumption of a shaft part designed by an auto parts manufacturer, and meanwhile the measured energy consumption of the shaft part was acquired by experimental measurement. The estimation accuracy is analysed and verified by comparing the estimated value and measured value. IntroductionEnergy is indispensible for the development of this modern society. Due to energy crisis and environmental pollution in energy generation (e.g. electricity generation by combustion of fossil fuels), the reduction of energy consumption not only benefits energy security and sustainable development of society but also improves environmental performances (Li, Hong, and Xing 2013; Rajemi, Mativenga, and Aramcharoen 2010). Therefore, energy efficiency has become increasingly vital (Seow, Rahimifard, and Woolley 2013). Particularly, products, for example machine tools, automobiles, turbines, account for a significant high proportion of total global energy consumption in their lifecycles. It has been proved that the reasonability of product design can exert a profound influence on reducing energy consumption of products in their future phases, such as manufacturing, transportation, usage and maintenance (Bonvoisin et al. 2013;Ingeneer, Mathieux, and Brissaud 2012), so energy-efficient design of products can play a key role in energy saving.Research suggests that energy-efficient design of products could start with predicting energy consumption of product design schemes in future phases, such as manufacturing phase, transportation phase and use phase, and further the product design schemes can be optimised based on the prediction information (Cao et al. 2012).
