This British Standard is an adoption of an ISO standard. You can access the ISO version here.
ISO 14955‑3 is part three of the multi-series standard that supports the energy-saving design methodology according to ISO 14955‑1 and the methods for measuring energy supplied to machine tools and machine tool components defined in ISO 14955‑2. ISO 14955‑3 addresses the environmental evaluation of machine tools during the use stage based on reference scenarios. It contains an example for metal cutting machine tools.
ISO 14955‑3 defines a methodological approach to assess relevant machine tool operating states based on an individual reference scenario for the energy assessment of machine tools and the integration of energy-efficiency aspects into machine tool design.
ISO 14955‑3 explains what needs to be measured in line with ISO 14955‑1 and ISO 14955‑2. Furthermore, it shows how a reference scenario for the measurement of the machine function “processing”, according to ISO 14955‑1, is evaluated.
The results from applying ISO 14955‑3 are influenced by the effect of user behaviour and manufacturing strategies during the use phase.
NOTE-
ISO 14955‑3 does not support the comparison of machine tools.
ISO 14955‑3 on principles for testing metal-cutting machine tools with respect to energy efficiency is useful for:
Machine tools are complex products for industrial use to manufacture parts ready for use or semi-finished products. The performance of a machine tool as key data for investment is multi-dimensional regarding its economic value, its technical specification, and its operating requirements which are influenced by the specific application. Therefore, the same machine tool can show quite different energy supplied to the machine depending on the part which is manufactured and the conditions under which the machine is operated. Therefore, the environmental evaluation of a machine tool cannot be considered in isolation from these considerations.
The reference scenario introduced in ISO 14955‑3 reflects the actual machine process in the field under best knowledge. The definition of the reference scenario and its measurement helps to indicate application-dependent improvement potential and the application of the methodology as defined in ISO 14955‑1 and related improvement measures for given industrially driven applications.
ISO 14955‑3 describes the procedure for the environmental evaluation of machine tools according to ISO 14955‑1.
