标准范围
This document specifies technical requirements and measures for testing procedures for evaluation
of energy required to be adopted by persons undertaking the design, manufacture and supply of
metal forming and laser processing machine tools in order to achieve reproducible data about the
energy supplied under specified conditions. Furthermore, it provides methods for quantifying the
energy supplied to components in order to assign their share to generalized machine tool functions as
described in ISO 14955-1.
Along with ISO 14955-1 and ISO 14955-2, it covers 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 annexes.
This document 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 work-pieces 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 can be used in
the same way to work other materials (e.g. cardboard, plastic, rubber, leather, etc.).
It also applies to auxiliary 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.
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.
