Verification of prediction method for energy consumption of machine tool feed axes

Abstract

Energy efficiency of electrical appliances is highly debated topic at present. This topic is transferred especially in industries where are the effects of savings much more significant due to higher energy consumption. In the case of machine tools is at present energy efficiency also a hot topic, based on the Kyoto Protocol and the European Commission Regulation of energy appliances eco-design. Machine tool manufacturers already responses to this situation by using more efficient components (motors, pumps, etc…).This article focuses especially on determining the energy profile of the machine tool at the moment where the machine is not manufactured. It is used a method allows to simulate the energy profile of the machine tool. This is verified by measurement on the test device. Realized measurement was done under different loads of clamping table and under different feed rates. Average percentual error was achieved below ten percent limit.Energy efficiency of electrical appliances is highly debated topic at present.
