Research on An Estimation Model for Energy Consumption in Machining Process

Abstract:

With the rise of the global low carbon manufacturing，energy consumption and utilization rate of the machining process have drawn increasing attention, and energy consumption has gradually become an important index of the machining process decision. Traditionally, the energy required for the cutting process is estimated based on cutting force prediction equations, this estimation is limited to the energy consumption of the material removal process. This paper divided the energy consumption of the machining process into three parts: fixed energy consumption, no-load energy consumption and cutting energy consumption, an energy consumption estimation model is proposed, parameters are determined by experiments. Finally, an actual milling case is illustrated indicated that the model is able to provide a reliable prediction of energy consumption for given process parameters, which would be the foundation of the subsequent process parameters optimization and process decision.
