“…Methods from the non-destructive testing group and quality management tools were used in the model because they are preferred in casting quality control and quality problem analysis. Many cited literature items confirm the effectiveness of applying the considered methods individually [ 41 , 85 , 86 , 87 , 88 , 89 , 90 , 93 , 94 , 95 , 96 , 97 ].…”

“…The literature on quality management often presents the issue of quality analyses supported by single quality management tools [ 85 , 86 , 87 , 88 , 89 , 90 ], or develops models in production process optimization [ 91 , 92 ]. However, no integrally configured quality control method has contributed to the realization of in-depth causal analysis of manufacturing non-conformities identifying the root cause of non-conformities.…”

An essential element of any industry is castings, which is determined by the technical conditions for their reception. However, conducting production in the foundry technology is burdened with many difficulties associated with, for example, the inability to control all of the parameters that may affect the casting quality. Therefore, it is essential to undertake improvement actions in this area. Efforts are being made to use non-destructive testing (NDT) as a part of quality control, but these methods are rarely combined in a single diagnostic run. As a part of quality improvement, it is also essential to identify the root cause of the problem. For this reason, it is justified to develop a model of diagnosing and searching for non-conformities, which would combine NDT tests and quality management tools. The model included the visual, ultrasound, and eddy current examination in the diagnostic part, and the Pareto–Lorenz diagram correlated with ABC method, histogram, and 5WHY method (asking five questions why). The study’s originality is manifested in the combination of several NDT methods with quality management methods in one model. Using integrally configured methods in the proposed model, it was possible to: reduce diagnostic uncertainty, characterize the critical group of non-conformities, and identify the root causes of the quality problem. The model is a new and universal method that can be implied in any foundry company in order to ensure the stability of the production processes. The application of the model contributes to an increase in the detection speed and enables the reduction of non-conformities in aluminium castings, thus increasing the quality level of the offered products.

“…In contrast to the final acceptance control, single control points of the technological process allow to draw attention to subsequent production processes in order to eliminate and prevent the occurrence of irregularities in the future. In addition, the identification of non-compliance immediately after the technological operation in which it arose results in separating the product from the further processing process and protect-ing the company from incurring unnecessary costs (further processing of incompatible product) [13,15,16,17,25,26]. In each of the designated control points it is possible to apply quality control with a division into two types of data: numerical data or alternative data, therefore it can be stated that each quality control is a numerical control (assessment of product properties takes place on the basis of measurable characteristics) or an alternative control (assessment of properties takes place on the basis of nonmeasurable characteristics (or measurable, but not measured), by comparison with a standard, and then a twostage assessment, e. g. "compliant product", "non-compliant product" or multivalent) [12,20,15].…”

The publication analyses the way of managing and improving the quality of the production process of aluminum pistons for internal combustion engines. The aim of the article is to propose a method of analysis of the effectiveness of individual control methods used in the process of controlling the aluminium piston. Thanks to the location of a control point with the highest share of product non-compliance detection in the production process, it is possible to reduce quality control points by less effective points, which will contribute to lower costs or shorten the time of production processes. In view of the increasing demands on the efficiency of the checkpoints for components in internal combustion engines, the issue is important and topical.

“…The methods of quality management that enable the activities indicated to be carried out are those which skillfully apply to increase the level of quality of the products offered [21]. Qualitative analyses supported by the use of individual quality management tools [22][23][24][25], or the use of these tools to optimize production processes [26,27] are often presented in quality management literature papers. It is, therefore, appropriate to develop a sequential method for analyzing and improving friction-welded connections.…”
