ISO DIS 14955-4

Description / Abstract: This document specifies the means of measuring the energy required for the design, manufacture and supply of metal-forming and laser processing machine tools.

Together, this document, ISO 14955-1 and ISO 14955-2 cover all significant energy requirements relevant to hydraulic (servo) and mechanical (servo) presses, turret punch presses and press brakes, pipe benders, laser processing machine tools, when they are used as intended and under the conditions foreseen by the manufacturer. Examples of how to perform energy evaluation on metal-forming machine tools are given in the document’s annexes.

This document also applies to ancillary devices supplied as an integral part of the machine tool and to machine tools which are part of an integrated manufacturing system where the energy required is comparable to those of machine tools working separately.

It is applicable to machine tools which transmit force mechanically or transmit energy by laser light to cut, form, or work metal or other materials by means of dies attached to or operated by slides, punches or beams as well as to lasers ranging in size from small high speed machine tools producing small workpieces to large relatively slow speed machine tools and large work-pieces. This document covers machine tools whose primary intended use is to work metal, but which may be used in the same way to work other materials (e.g. cardboard, plastic, rubber, leather, etc.).

This document does not give test procedures for the energy requirements of tools or dies attached to the machine tools.

It is not applicable to machine tools whose principal designed purpose is

— metal-cutting by milling, drilling or turning,

— metal-cutting by oxygen or water cutting,

— attaching a fastener, e.g. riveting, stapling or stitching,

— bending or folding by folding machine tools,

— straightening,

— extruding,

— drop forging or drop stamping,

— compaction of metal powder,

— single purpose punching machine tools designed exclusively for profiles, e.g. used in the construction industry,

— working by pneumatic hammer,

— working by pneumatic presses.

NOTE Mechanical servo presses are also known as servo electric presses.
