NBN ISO 14955-2:2021

This document describes how measurements are made by providing measuring methods in order to
produce reproducible data about the energy supplied to a machine tool under specified conditions.
Furthermore, it provides methods to quantify the energy supplied to components in order to assign
their share to generalized machine tool functions as described in ISO 14955-1.
It supports the energy-saving design methodology according to ISO 14955-1 by providing measuring
methods for the energy supplied to machine tools. The assignment of the energy supplied to machine
tool functions requires measurements at machine tool component level. These measurements need to
be reproducible and independent of conditions other than those being recorded and documented.
The results of the measurements are intended to document improvements to the design, specifically
under energy aspects, and/or to allow evaluating the energy involved in the manufacturing of a given
part by a given machine tool. Any comparison requires identical conditions and ensures by specification
and measurement that similar results are achieved.
