Development of Testing Machines and Equipment for Small Punch Testing, Proposals for Improvement of CWA 15627

Abstract:

The need to determine the mechanical properties of materials of machine parts working in operating conditions without shutdown of the entire unit and disintegration machine parts in the past led to the development of miniaturized specimens associated with the generation of special test procedures and methods. During many years the developed methods have been refining, the results are compared with conventional testing methods, the shape and dimensions of specimens are modified. The enormous development of information technologies in the last decades enabled the emergence of a new field of science - mechatronics - a multidisciplinary field of engineering that includes a combination of systems engineering, mechanical engineering, electrical engineering, telecommunications engineering, control engineering and computer engineering. Progress in the field of mechatronic together with development of new materials, new CNC machining methods for metallic and non-metallic materials, miniaturization of sensors of physical quantities, fast, accurate data sampling and recording significantly influenced the development of the testing devices and allowed to construct machines which was not possible in the past.Content of this paper presents the latest design, features of a test device for determining the residual life of machine components working at elevated temperatures (SPUTT500®), equipment for tensile and fracture testing small samples under the normal and low temperatures (CRYOSET®) and the scoop sampling machine (ESTIM®) used not only for further research but also for development and evaluation of small samples testing technology. The final part of this article comprises the proposal for improvement the Code of practise for small punch testing (CEN Workshop Agreement 15627).
