A new framework of energy-efficient manufacturing systems based on energy load profiles

It has become more crucial to apply energy-efficient optimization not only to individual manufacturing factors but the whole manufacturing systems with the aim of greening of manufacturing. This study proposes an energy-efficient optimization technique for operations in a flexible manufacturing system with several machine tools by introducing a concept of a processing mode and energy-load profile. This study focuses on how a processing mode, describing machining conditions involving energy-aware operations, is derived and conducts some cutting experiments. An optimization model to generate the energy load profile is also formulated and it is demonstrated that the energy load profile has a role of the basis for energy-efficient machining operations as well as the manufacturing system through some computational simulations.
