The principles of the friction welding (FW) process of the two different non-ferrous metals, aluminum and copper, are presented in this paper. Considering that the bimetallic Al-Cu joints find applications in electrical engineering, as well as in other industrial fields, the basic characteristics and compatibility of these metals are discussed, alo...

Reverse engineering is a technique that has recently been used in all areas of industry. The application of reverse engineering in the auto industry occupies a very important place. 3D scanners are often used to digitize parts with fine details or large sheet metal, and they can be very expensive. In this paper, the possibility of using photogramme...

This paper explores the effects of tempering temperatures on the mechanical properties of G42CrMo4 cast steel, a versatile alloy commonly used in automotive and construction industries. Tempering, a critical step in the heat treatment process, aims to reduce residual stresses and enhance material reliability. The study investigates the influence of...

Purpose The impact of the application of hollow structures through variations of infill patterns and their density on the tensile properties was considered. The mechanical properties of the parts have a significant influence on the behavior and reliability of the parts in exploitation. Design/methodology/approach In this paper, the mechanical prop...

The aim of this paper is to show influence of two elements on plastic strain ratio value, or "r" value. The first element is value of plastic strain, and second is specimen geometry. Extensive experiment was conducted according to appropriate tensile test procedure with 3 materials and 5 different specimen geometries. Steel sheet S235JR, austenitic...

This paper are relating to anisotropy of thin sheet metals phenomena, especially to, so called, normal (orthogonal) anisotropy which expresses by plastic strain ratio, or "r" value. The paper presents the results of experimental investigation which main goal was to evaluate influence of two elements of plastic strain ratio experimental method of de...

In the common industry and especially in military industry there is a growing need for production of highly effective protective structures. For that purposes the most used materials are armor steels. They belong into a group of the fine-grained, increased strength steels, which are manufactured by intensive thermo-mechanical treatment at high temp...

The application of numerical simulations of production technologies, using the finite element method or the finite volume method, is a widely used approach in advanced engineering design and research. Unlike industrial experiments, this approach allows the analysis of the influence of different process parameters on the output performance of a work...

The paper presents the integrated application of additive manufacturing and reverse engineering technologies for the rapid tooling for two-component plastic casting, as a faster and cheaper approach than injection moulding, particularly for small-scale production of plastic parts or spare parts when CAD models and technical documentation are not av...

Comparison of application of constant and variable lateral force in strip ironing process with double side thinning are presented in the paper. Given are the experimental results for single and multiphase ironing process with constant lateral force during the course of particular process. Material used was mild steel DC04. Stripes were 20 mm wide a...

In this paper, the research results of the stability of steel welded tubes forming process are presented. The aim of this research is to determine influence of geometrical and tribological parameters on stability of the process and to determine optimal values of influential process parameters. A research plan with variation of influential parameter...

The paper deals with the experimental-numerical analysis of the hot forging process on a hammer, where the main focus is on monitoring the thermal effects that occur in this metal forming technology. This includes measuring and numerically estimating the temperature fields in the workpiece and forging tools in multi-stage forging process. For this...
