“…The presented article introduces a prototype of a flexible cup for a harmonic drive, which due to its significant possible gear ratios and high precision, can find applications in hydraulic control [29][30][31] and the military sector [32][33][34]. Due to the multidimensional dependencies, the implementation of formal statistical techniques [35][36][37], including expert systems support [38] and nonparametric approaches [39][40][41], is necessary.…”

Abstract. This article presents an analysis of the geometrical accuracy of flexspline prototypes that were a component of harmonic drive. To produce the test models, a MEM (Melting and Extrusion Modeling) method was used. This additive method allows the production of elements with very complicated shapes from various polymeric materials. As the test model, a flexspline made of ABS (acrylonitrile-butadiene-styrene) was assumed. Such a special gear with a complicated construction was chosen, because its unique design allows one to obtain clear conclusions from the analysis. To expand the scope of research, models of flexspline with four different construction solutions were made and tested. As a step of the analysis, contact measurements were performed for several flexspline models on the coordinate measuring machine to check their dimensions. The verification of the geometrical accuracy of flexspline models will allow to assess the usefulness of additive methods for the production of prototypes and finished products.

“…Such multifactorial organizational and technological changes require a systematic approach to ensure the reliability and accuracy of the implemented modifications. In this regard, the methodology of experimental planning [48][49][50] is invaluable, as it allows for handling poorly defined variables in specific cases [51][52][53]. Ultimately, the introduced changes, by enhancing the quality and reliability of products and services, lead to simplified scenarios of potential failures and their consequences [54][55][56].…”

Abstract. Problems with product quality during negative climate changes make the continuous improvement process difficult. The search for approaches consists of methodical and possible detailed analysis areas of these types of problem types. Therefore, the objective of the article was to develop a method to analyze problems with the quality of products considering the impact on the natural environment. The method was developed by a coherent combination of selected techniques, i.e.: brainstorming (BM), Ishikawa diagram, 5M rule, multiple voting, seven-point Likert scale, and the IPA method. A method was carried out for mechanical seal of the 410 alloy, on which a porosity cluster was detected. The originality of the study is that the proposed method supports a consistent methodical analysis of any problem with the quality of products and verifies these problems in view of their impact on the natural environment. Simultaneously, the result obtained from the method determines the main causes of the problem, from which to begin improving the quality of the product considering the impact on the natural environment. This method can be applied to any product and the incompatibilities detected on them. Therefore, the method can be used in service-production enterprises to improve products in terms of qualitative-environmental.
