Purpose: The paper presents the issues of designing the maintenance of materials and products in accordance with the idea of Industry 4.0. The author's views on the need for augmentation of the Industry 4.0 model were also presented, as well as the author's original concept that hybrid activities in predictive maintenance and condition-based maintenance should be preceded by designing material, maintenance & manufacturing 3MD at the stage of the product's material designing and technological designing. The 3MD approach significantly reduces the frequency of assumed actions, procedures and resources necessary to remain the condition of this product for the longest possible time, enabling it to perform the designed working functions. Examples of own advanced research on several selected, newly developed materials, used in very different areas of application, confirmed the validity of the scientific hypothesis and the relationship between the studied phenomena and structural effects and the working functions of products and their maintenance and indicated that material design is one of the most important elements guaranteeing progress production at the stage of Industry 4.0 of the industrial revolution. Design/methodology/approach: The author's considerations are based on an extensive literature study and the results of the author's previous study and empirical work. Each of the examples given required the use of a full set of research methods available to modern material engineering, including HRTEM high-resolution transmission electron microscopy. Findings: The most interesting intellectual achievements contained in the paper include presentations of the author's original concepts regarding the augmentation of the Industry 4.0 model, which has been distributed so far, which not only requires augmentation but is actually only one of the 4 elements of the technology platform of the extended holistic model of current industrial development, concerning cyber-IT production aided system. The author also presents his own concept for designing material, maintenance and manufacturing 3MD already at the stage of material and technological design of the product, eliminating many problems related to product maintenance, even before they are manufactured and put into exploitation. Detailed results of detailed structural researches of several selected avant-garde engineering materials and discussion of structural changes that accompanying their manufacturing and/or processing are also included. Originality/value: The originality of the paper is associated with the novelty of the approach to analysing maintenance problems of materials and products, taking into account the requirements of the contemporary stage of Industry 4.0 development. The value of the paper is mainly associated with the presentation of original issues referred to as findings, including the concept of augmentation of the Industry 4.0 model and the introduction and experimental confirmation of the idea by designing material, maintenance and manufacturing 3MD.

Publikacja zawiera wybrane przykłady, zdiagnozowanych parametrami elektrycznymi, stanów krawędzi krzemowych ogniw fotowoltaicznych po procesie cięcia typu WEDM. Przeprowadzano wiele prób podziału ogniwa krzemowego przecinarką elektroerozyjną, dokonano analizy struktur geometrycznych powierzchni, będących pochodnymi zastosowanych parametrów i metod cięcia wafli krzemowych. Konkluzje prowadzą do zachodzących znaczących związków między stanem powierzchni po wykonanym cięciu krzemu a parametrami użytkowymi ogniw słonecznych. Aby fotowoltaika stała się tanią i powszechną postacią konwersji energii, konieczne jest udoskonalanie rozwiązań w zakresie procesu produkcyjnego typowych ogniw krzemowych, zwłaszcza poprzez efektywniejsze techniki oddzielania materiału oraz doskonalenie kryteriów oceny stanu ich powierzchni po cięciu.

Publication contains chosen examples of applied processings, diagnosed by electric parameters. Describes the conditions of the edge of photovoltaic silicon after the WEDM cut process. The sequence of the tests of the conventional cutting in the silicon cell carried out by disc cutting. Then analyses of surfaces were executed, being derivative of the applied parameters in the methods of the cut of silicon wafers. Conclusions guide to drawing significant relationships between the condition of the surface after executed cuts of silicon and the usable parameters of solar cells. PV systems will be happened the cheap and popular figure of the energy conversion. Refining the solutions in the range of the productive process of typical silicon cells is the necessity, especially through the more effective technics of the separation material and by the building the criteria of the rating of the condition their surface after cutting.
