Role of materials design in maintenance engineering in the context of industry 4.0 idea

Dobrzański L. A.

Journal of Achievements in Materials and Manufacturing Engineering

2019

Vol. 96, nr 1

12--49

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.

Synergic effects of the scientific cooperation in the field of materials and manufacturing engineering

Dobrzański L. A.

Journal of Achievements in Materials and Manufacturing Engineering

2006

Vol. 15, nr 1-2

9--20

Purpose: The paper emphasises the very significant role of materials selection for design and manufacturing processes of new needed products, having the highest attainable quality and performance at the optimum and possibly the lowest cost level. Design/methodology/approach: The engineering design processes cannot be set apart either from the material design, being more and more often computer-aided, or the technological design of the most suitable manufacturing processes. Findings: The attention was paid to synergic effects of the cooperation with the specialists of various branches what was a basis of the successful series of the International Scientific Conference AMME and the foundation of the World Academy of Materials and Manufacturing Engineering. Practical implications: The paper includes also the description of the world developmental trends in that area in the first decades of the 21st century. The tasks of that field of science in priority spheres of the world development are determined. Originality/value: Directions of activities of materials science and engineering ensuring the achievements of strategic aims of the developments of societies include materials design, computational materials science, advanced analytical methods, manufacturing and processing, nano-, smart and biomimetic materials are included. It is concluded that there is a humanistic mission which stands at the engineering circle, especially associated with materials and manufacturing engineering and its aim is to make products and consumer goods, deciding directly about the level and quality of human life.
