ISO issues new standards for machine tools
The International Standard Organization (ISO) recently released a new series of standards, aiming to make machine tools more environmentally friendly.
The energy demand for machine tools is a key element in the evaluation of the investment, and yet it is not an isolated factor. The performance of a machine tool is multidimensional regarding its economic value, its technical specification and its operating requirements, which are influenced by the specific application.
This is why the environmental footprint of a machine is a common challenge for all operators, and as natural resources become scarce, environmental-performance criteria for machine tools must be defined and applied properly and uniformly.
To provide a solution to this challenge, the ISO technical committee ISO/TC 39 developed the ISO 14955-1 and ISO 14955-2. The goal is to help measure the energy supplied to CNC machine tools and improve machine design and performance.
“This is, to my knowledge, the only standard concerning this topic that is tailored for machine tools,” said Ralf Reines of the ISO technical committee 39/working group 12, which developed the standards. “It covers the topic in a way that can be applied to each and every machine tool, despite the fact that the product group of machine tools is extremely diverse, e.g., different technologies, processing of material and sizes. The standard focuses on the relevant energy users need to achieve a higher environmental performance without losing in technical possibilities.”
