The article presents the selected results of strength tests on the effectiveness of bonding high-alloy steel 1.4310. Sheet steel is one of the materials that are difficult to activate energy. Effective joining of it is difficult, requires selection of the appropriate bonding technology. The paper focuses on the comparative tests of shear strength of one-single lap welded and bonded joints. The welding...
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...
The article presents achieved results of research focused on the influence of various factors modification on cutting forces at longitudinal turning of steel C 45 using two tools with different shape and geometry at constant values of feed and depth of cut. The individual components of cutting force were compared reciprocally, i. e. axial, radial, tangential and finally resulting cutting force depending...
The aim of this study is to determine the usefulness of selected 2D roughness parameters for detecting changes of geometric features and the rate the quality of the surface generated in the process of honing combustion engines sleeves. The paper presents the importance of mathematical modeling of virtual surface topography with different participation of determined and random factor. The possibilities...
This article presents selected criteria for the quality assessment of single-lap adhesive joints formed on 0.66±0.04 thick hot dip zinc coated sheets with the hot dip zinc coating thickness equal to 18 μm. Three types of epoxy adhesives and three variants of the mass of adhesives were tested (1 g, 2 g and 3 g). The work intended to assess the capacity of the visual method with regard to evaluating...
The technical practice requirements comes to have increased demands on higher productivity, speed and quality of the machining process of various materials. Hard to machine materials, whose machining led to the development of turning with rotating cutting edge are not an exception. The machining process of auto-rotating tool is more complicated than the conventional process of turning, especially...
W artykule zaprezentowano fragment badań, związanych z mechanicznym przygotowaniem powierzchni blach ze stali odpornej na korozję do klejenia. Badaniom poddano próbki połączeń klejowych jednozakładkowych, w których powierzchnie blach ze stali nierdzewnej przygotowano przy użyciu obróbki mechanicznej ściernymi narzędziami nasypowymi o różnej ziarnistości (P120, P320, P500) oraz za pomocą odtłuszczania...
Due to customer driven economies, today’s world markets are characterized by high fluctuations in market demand and frequent arrival of new technologies and new products. To stay competitive in such markets manufacturing companies require continuous improvements both in technical and organizational areas of their activity. The paper presents results of the diagnosis provided in the manufacturing area...
This work deals with investigation of residual stresses during by non-destructive methods turning. Workpiece material, which was used in experiments was 19 830 steel, which is used for rolling bearing rings. Residual stress were observed in the application of various cutting parameters by non-destructive methods.
