This part of ISO 14955 constitutes the application of eco-design standards to machine tools, mainly formetal working numerically controlled (NC) machine tools.This part of ISO 14955 addresses the energy efficiency of machine tools during the use stage, i.e. theworking life of the machine tool. Environmental relevant stages other than the use stage and relativeimpacts other than energy supplied to machine tools are not within the scope of this part of ISO 14955and need a special treatment (e.g. according to ISO/TR 14062).Elements of eco-design procedure according to ISO/TR 14062 are applied to machine tools. Reporting ofresults to users and suppliers and monitoring of results are defined.Evaluation of energy efficiency implies quantification of the resources used, i.e. energy supplied, and ofthe result achieved. This part of ISO 14955 provides guidance for a reproducible quantification of theenergy supplied. It does not suggest a methodology for quantifying the result achieved due to the lackof universal criteria. The result achieved in industrial application being machined workpieces, theirproperties (e.g. material, shape, accuracy, surface quality), the constraints of production (e.g. minimumlot size, flexibility), and other appropriate parameters for the quantification of the result achieved areintended to be determined specifically for each application or for a set of applications.This part of ISO 14955 defines methods for setting up a process for integrating energy-efficiency aspectsinto machine tool design. It does not support the comparison of machine tools. Also, this part of ISO 14955does not deal with the effect of different user behaviours or different manufacturing strategies duringthe use phase.Lists of environmentally relevant improvements and machine components, control of machinecomponents, and combinations of machine components are given in two informative annexes, one formetal-cutting machine tools (Annex A) and one for metal-forming machine tools (Annex B). Annex Cprovides an example of application of the methodology. Other machine tools, e.g. laser-cutting machinetools, material additive machine tools, and woodworking machine tools are currently not covered byinformative annexes.NOTE Certain machining processes and specific machine tools can allow significant changes in theenvironmental impact of machined workpieces, e.g. material reduction for aluminium cans by application ofspecial press technology, higher performance of compressors by machining on precision form grinders.[3][5] Theenvironmental impact of such processes or machine tools might be less important compared to the environmentalimpact of the machined workpieces and their application. These changes in the environmental impact of machinedworkpieces are not subject of this part of ISO 14955 but might be important if different machining processesor different machine tools have to be compared related to environmental impact of products. For instance, theaccuracy of a machined workpiece might be a significant parameter for the environmental impact of the workpiecein its use stage, and any attempt to compare machine tools is intended to take this into account necessarily.
