Energy efficiency evaluation method for machine tools

Abstract

The energy efficiency of machine tools is typically poor and there is potential to increase it. It is possible to effect the energy consumption of a cutting process by selecting suitable process parameters and tools. When the power usage of the machine tool is measured by cutting experiments, the energy efficiency of the machine tool effect of the results and the cutting process has an influence. This paper presents the impact of several cutting parameters affecting the cutting power, the machine tool electric power usage and the efficiency. Furthermore, the possibilities to adjust the cutting power by changing the process parameters is used in developing a shop floor level method for evaluating and comparing performance of different machine tools.
