Energy performance improvement is a basic significant way of addressing both energy security and environment concerns, which can promote energy-saving and emission-reduction. There are various measures of energy performance, with different purposes and applications. However, there are few models or approaches for measuring and quantifying energy saving potential in machining systems. To better perform the energy performance analysis and evaluating energy saving potential in machining, an energy performance evaluation method based on energy benchmark in machining systems is addressed. Energy performance characteristics is analysed, and some energy performance concepts and indicators are proposed. The energy performance evaluation based on energy benchmark is developed for machining systems. Furthermore, a case study involving the establishment of an energy performance evaluation and energy saving potential for gears in a real machining plant was examined, illustrating the practicability of the proposed method.
