The identificationof incompatibility in the process of laser cutting of the semi-finding

Abstract

Abstract. This paper presents selected quality tools that have been used to identify incompatibilities and their causes in the laser cutting process. As a result of the studies and analyzes, it was found that errors made by the TPM Maintenance Services, such as the failure of the laser to be included in the inspection and maintenance schedule and improperly scheduled employee training, led to the production of some 4500 non-compliant products per batch, representing about 30% products in each batch. The research has made it possible to identify the causes of nonconformity and to plan the correct actions to eliminate them.Keywords: TPM, production, quality tools, production management, production process, incompatibilities IDENTYFIKACJA NIEZGODNOŚCI W PROCESIE CIĘCIA LASEROWEGO PÓŁPRODUKTU Streszczenie. Artykuł przedstawia wybrane narzędzia jakości, które posłużyły do identyfikacji niezgodności i ich przyczyn w procesie cięcia laserowego. W wyniku przeprowadzonych badań i analiz ustalono, że błędy popełnione przez służby Utrzymania Ruchu TPM, takie jak: nieuwzględnienie lasera w planie przeglądów i konserwacji maszyn oraz niewłaściwie zaplanowane szkolenia pracowników, doprowadziły do wyprodukowania około 4500 wyrobów niespełniających wymagań na partię, co stanowi około 30% niezgodnych wyrobów 430 B. Szczucka-Lasota, R. Wolniak, M. Fryc w każdej partii. Przeprowadzone badania umożliwiły określenie przyczyn niezgodności oraz zaplanowanie właściwych działań w celu ich eliminacji.

A New Model Supporting Stability Quality of Materials and Industrial Products

“…Next, all causes are grouped according to the 5M rule (man, method, machine, material, and management). This rule is preferred to analyze the quality of industrial products [19,20]. The 5M is used in the Ishikawa diagram to group the causes of the problem.…”

“…The literature review shows that to verify incompatibilities of industrial products, the most frequently used methods were brainstorming (BM), Ishikawa diagram [17], Pareto-Lorenz [18], and the 5Why method [19]. The Ishikawa diagram and the Pareto-Lorenz diagram were used to verify the causes of incompatibility of industrial products [18][19][20][21].…”

“…The literature review shows that to verify incompatibilities of industrial products, the most frequently used methods were brainstorming (BM), Ishikawa diagram [17], Pareto-Lorenz [18], and the 5Why method [19]. The Ishikawa diagram and the Pareto-Lorenz diagram were used to verify the causes of incompatibility of industrial products [18][19][20][21]. For example, in study [18], the structure of the pulley defects was assessed, where the Pareto diagram was used to identify the most important incompatibilities, and the Ishikawa diagram was used to determine the causes of these incompatibilities.…”

“…Firstly, all defects were verified by causes and effects diagrams, and then the most important defects were identified by Pareto analysis. In a similar way, the authors of the study [19] analyzed the laser cutting process, where the 5Why method was used to verify the main causes of incompatibility in this process. However, in study [20], the general purpose technological analysis (GPT) was verified using the Ishikawa diagram.…”

“…However, in view of the specificity of special processes occurring in the mechanical industry, it seems adequate to realize the initial test, for example, for the casting process. That resulted from a review of the literature on the subject [18][19][20][21]24,26,29], after which it was proved that the most frequent errors occur due to foundry processes. Therefore, the modeling was tested for cracks in the outer hull of the four-point bearing of alloy 418 (CPW-S 5616).…”
