Simulation-assisted Investigation of the Electric Power Consumption of Milling Processes and Machine Tools

The worldwide increase in energy prices and energy consumption in recent years have led to a redirected and increased focus on energy efficiency in the industries. This paper analyses the distribution of the electrical power consumption of the components of different milling machines. Previous experiments showed that auxiliary components like cooling and control use a major share of the total electrical energy input. In an attempt to optimise the machining process, an approach to model the power input of machining centres using an empirically generated database of the basic load and a geometric, physically based model for depicting the cutting power is presented.
