This article deals with the forming of sheet metal on a bending machine. The bending of sheet metal cut shapes or clippings is a very common operation in many companies. Oftentimes, many of these companies deal with the issue of how to bend the sheet metal to the required precision, especially while complying with the required bending angle. The sheet metal is bent correctly while it is in between the tools of the machine. However, stress develops in the material during bending and this stress remains in the mater...

This article discusses the possibilities of recycling waste material generated using 3D FDM or FFF printing technology and its use in the re-production of printed material. Additive technology is an increasingly popular method for the rapid design of components and machinery parts. It enables creating prototype components and assemblies relatively quickly. This makes it possible to search for the right design of a given component and to choose from several options (e.g. finding the correct shape in ergonomics). Ho...

This article discusses the possibilities of using a 3D printer with parallel kinematics that can produce good quality prototype components such as various covers, handles and functional assembly for simple electronic devices or robots. It will enable combining the printer with an engraving CNC machine, so that the effector head of the 3D printer will allow the head to be exchanged for printing with an engraver head, and it will allow fine engraving on printed circuit boards. The printer effector is equipped with a...

Aim of this paper is to provide the overview of ecological friendly mechanical engineering through design solution in the field of material handling. There can be achieved a significant reducing of energy consumption with advantage of maintenance simplicity by decreasing level of the automation and the design complexity. Model situation is dealing with change of the material position orientation by using minimum of external forces and processes. The orientation change is induced by motion of the material along pre...

Development of energy, nuclear, engineering, petrochemical and chemical industry requires very massive and large workpieces. Requirements for machining workpieces of these department is the necessary adapt to the design and construction of machine tools. Analyses were conducted to carry out the overhaul and modernization for heavy cutting machine SKODA W 200 HC with digital subtraction, turntable S 100 C from 0 to 360пїЅ, while the carrying capacity of the turntable 100 t. The complexity of the repairs consisted o...

This article deals with the modification of the nozzle and its entire assembly with a hot end, so that it was not necessary to use a tephlon insertion and it was possible to reach the maximum temperatures of the nozzle reaching 280пїЅC and above. With the gradual development of 3D printing technology FDM (fused deposition modeling), i.e. the fritting of the thermoplastic in the shape of the fibres and putting it into the layers, more demands are placed on the materials used. Materials with a greater temperature of...

The aim of this article is to describe the possibility of increasing the service life of the rod eye on a tilting platform that is used to tilt heavy barrels between the two differences in heights in transport lines. This mode of transport was selected for the lack of space in a given area of a production line, which does not allow the implementation of an inclined plane, which would be structurally easier. Rotating those barrels by 90пїЅ that is achieved during this way of transport, is desired for subsequent tec...

When building the foundations of a machine tool, demands must be placed on high quality and, above all, on their stability during their entire lifetime. In practice, however, it shows that these requirements are not always fully met on the customerпїЅs side when laying foundations. In the course of working, these foundations are subsequently damaged and their uneven decline occurs, which results in a change of the machine alignment, and thus it also influences the accuracy of production. For the supplier of the ma...

The technology of cutting with a plasma arc is today a very advanced solution for thermally cuttable conductive materials. Plasma or also the plasma arc is composed of positively and negatively charged particles, excited and neutral atoms and molecules. As it contains free particles, it is electrically conductive and thus subject to the effects of an electric and magnetic field. This article discusses the use of plasma cutting technology on a CNC machine. The resulting quality of the plasma cutting is determined b...
