Opis:: The article deals with issues related to quality management and quality assessment in production of plastic articles in injection moulding. Expert knowledge collected in textbooks and literature allows to get acquainted with the characteristics of plastic article production and product quality defects arising in such processes. The characteristics and technology of plastics processing are discussed, the most frequent quality defects occurring in the production of articles made of plastics by injection molding are listed. On the basis of expert knowledge collected in the literature, a series of actions leading to the elimination of each of the mentioned quality defects has also been proposed.

Opis:: This paper describes a stability study of a plastic injection molding process. There is a need - underpinned by economic considerations - to continuously improve and lead to a maximum reduction in the level of deficiencies in production processes. One of the methods that can help to improve the process is SPC (Statistical Process Control). One of the SPC tools are proces capability indicators (Cp, Cpk) or performance indicators, such as Pp, Ppk. In this paper, on a mass measuring station, a study was conducted on three types of products manufactured in a company, and the measurements concerned each piece of the product manufactured during one work shift. The data collected were used to calculate the process capability and to evaluate these processes.

Opis:: This paper investigates the effect of additive manufacturing parameters on the manufacturing quality of selected gear mechanism components. Three input variables, and two output variables were determined. The result was the determination of the most optimal combination of key parameters and the determination of regression equations. The concept of manufacturing objects of a very complex shape, by any person, under various conditions through the use of a low-cost device became the basis for this thesis topic. Curing time, layer thickness, and lift speed are among the basic parameters, with a large range of manipulation. A hypothesis was formulated that these three parameters are crucial to produce a part with the smallest possible deviations from the computer model. A handheld scanner was used to scan the samples and compare them with the CAD model. Based on the study, optimal parameters for layer thickness, curing time and lift speed were proposed.

Opis:: The main goal of the work was to create a project to implement an object recognition system into a modular didactic gear production system. The project shows how, thanks to the modular structure of the gear system, it is possible to easily add new elements to it, at the same time increasing its capabilities. At the beginning, the characteristics of the system were presented before the implementation, including a description of the production process that takes place in this system and all modules of the system were exchanged. Then the vision system for object recognition and all its components were described. The technical-organizational project of the implementation presented the concept of the deployment of the system modules and the principle of system operation after the implementation. A 3D model of all system components was also presented.
