Przeprowadzone badania doświadczalne miały na celu określenie wpływu przygotowania powierzchni na wytrzymałość połączeń klejowych blach stalowych. W badaniach przyjęto jedną z możliwych metod obróbki mechanicznej – obróbkę ściernymi narzędziami nasypowymi, ze względu na niski koszt oraz możliwość dobrego rozwinięcia powierzchni, co ma wpływ na wytrzymałość. Wykorzystane zostały papiery o różnej wielkości ziarna tj. P120, P320, P500 oraz P800. Dodatkowo zastosowano dwa warianty przygotowania powierzchni. Pierwszy wariant to obróbka mechaniczna przy pomocy wyznaczonego narzędzia nasypowego, a drugi to obróbka mechaniczna i dodatkowo odtłuszczanie powierzchni próbek. Po przygotowaniu powierzchni próbek zostały one sklejone z użyciem przygotowanego kleju (mieszanina żywicy epoksydowej Epidian 57 oraz utwardzacza Z1 w stosunku 100:10). Po określonym czasie utwardzania próbki były poddane badaniom wytrzymałościowym. Zauważono, że największą wytrzymałość na ścinanie w rozpatrywanych wariantach osiągają połączenia, których powierzchnie zostały przygotowane przy użyciu papieru ściernego P320.

The aim of experimental studies was to determine the influence of surface treatment on the adhesive joints strength of steel sheets. In a study accepted one of the possible methods of machining – abrasive machining grinding tools. This kind of tools was used due to its low cost and the ability to fairly good development of the surface, which affects the strength. The sand papers with different grain size (P120, P320, P500 and P800) were used. Two variants of surface treatment were tested. The first variant was the mechanical treatment by using the tested grinding tools and the second variant consisted mechanical treatment and degreasing by using Loctite 7063 degrease agent. After surface treatment the samples was joined by using the adhesive as a compound of Epidian 57 epoxy resin and Z1 hardener in the ratio of 100:10. After curing the samples were subjected to strength tests. It was noted that the highest shear strength was achieved for samples, which surfaces were prepared using sandpaper P320.

The following paper analyses selected problems regarding the impact of technological parameters and the type of adherend material on the strength of adhesive-bonded steel sheet joints. The subject of the test was a single-lap adhesive joint of S235JR steel sheet. Joints were formed on two types of substrates: with or without corrosion products on the surface. The surface of steel sheet adherends was pre-treated with three cleaning solutions: acetone, Wiko industrial degreasing agent and Cortanin F anti-corrosion agent, depending on the state of the surface. Adhesive joints were formed with Epidian 53/ET/100:15 epoxy adhesive. The formed joints were subjected to one of three ageing variants: 14 days, two months and 3 months, which were followed by destructive testing to determine the shear strength of joints. The analysis of results obtained in the tests indicates that the strength performance of adhesive joints of corrosion-free adherends was characterised by higher values than in corroded steel sheets, regardless of ageing time.

Maintaining machinery in conditions capable of production requires certain level of maintenance which should be planned in order to avoid unnecessary downtiqmes. Technical diagnostics and monitoring provides data necessary for effective targeting, planning, and optimizing maintenance actions. This article describes a proposal of a system designed for monitoring various parameters on educational machine tools of EMCO Concept series, which are widely used at schools and universities and therefore, relatively easily accessible for research without any issues regarding confidentiality, common in industrial applications. The article describes a situation for which the device was designed, measured parameters, sensors its implementation and testing.

The presented article deals with analyses and testing appropriate parameters for the production of components manufactured with rapid prototyping technology – Easy- 3DMaker printer. The quality of the printed component with a specific shape is analyzed. The analyzed materials are ABS Printplus and PLA Printplus. These materials are printed at different temperatures and speeds. combinations of different settings were tested in order to find the best conditions for printing with different nozzles. The quality of individual printed samples is assessed visually and by touch. The efficiency in terms of print time under various conditions was also analyzed. The main benefit of testing is the establishment of appropriate conditions for printing components on a Easy3DMaker printer. The article does not focus on mechanical properties of the examined samples.

Defined data types are provided as part of the language. Every attribute, local variable or formal parameter has an associated data type. The core information modelling language consists of data types that determine its modelling capabilities. Based on the data types of traditional programming languages, language EXPRESS absorbing mechanisms used in object-oriented technologies, such as inheritance mechanism which is used to describe the production data, using a wide range of data types. This article dealt with the data types of EXPRESS language, and describe their basic options.
