ISO push for environmental evaluation of machine tools

By Niranjan Mudholkar,

Says, new standard focuses on the relevant energy users to achieve a higher environmental performance without losing in technical possibilities

energyefficiency

A new series of ISO standards can help measure energy supplied and improve machine design and performance. Machine tools obviously use different forms of energy, such as electrical energy, compressed air, hydraulic energy, energy hidden in the cooling and lubrication system, etc. Therefore, the energy demand of a machine tool is considered as key data for investment but does not stand alone. ISO has recently published the first two parts of a new International Standard for the environmental evaluation of machine tools, which proposes to analyse machine tools with regard to the delivered functions in order to highlight the commonalities in the huge variety of existing machine tool types.

ISO 14955-1, Machine tools – Environmental evaluation of machine tools – Part 1: Design methodology for energy-efficient machine tools, addresses the energy efficiency of machine tools during their working life. It identifies the main functions and machine tool components that are responsible for energy demand during the use phase. These components are then compared with previous components or with the state-of-the-art for their future improvement.

ISO 14955-2, Machine tools – Environmental evaluation of machine tools – Part 2: Methods for measuring energy supplied to machine tools and machine tool components, supports the energy-saving design methodology according to ISO 14955-1 by providing practical methods for measuring the energy supplied to machine tools.
