This paper presents a holistic development methodology with functional correlations between the mechanical and electrical parameters which is used for an optimization of feed drive systems with more than one drive. Within this process-oriented development methodology, the adaption of the controller is of central importance. Using the example of a new designed linear drive characterized by two mechanical (…)
Forward extrusion is typical way of mass-production of cold formed bars or rods with constant cross section. This process is used for production of engine alternator shafts and it is based on reducing the diameter of semi-product without removing material in several reductions. However, there is a potential danger of the chevron cracking. Chevron cracks are inside the material and therefore invisible on (…)
Virtual reality (VR) is a widely used platform for Product Lifecycle Management (PLM) support. Visualization of a virtual prototype in any phase of product or process design is important for making decisions about further development, testing and simulations. While the designers working on a particular product know its exact appearance, other personnel taking part in the development may need to use some (…)
When performing the evaluation of engineering structures, today’s designers fully depend on software tools available to their employer. The choice of a software program for design calculations and evaluation of structural elements is typically dictated by its price. Where the demand for engineering design services involves simple structures, the designers turn to single-purpose programs based on enginee (…)
Not only European population but also many countries in the world are being influenced by the population ageing. Regarding to those changes the actions have to be taken in areas like pension system or health care. The paper focuses on other very important area which is working environment and conditions. Adaptations of current schemes and limits valid for production planning in these days have to be don (…)
The article evaluates and compares PVD coatings. The theoretical part of the paper informs about principle of PVD coating technology and describes the arc evaporation method used for coating in greater detail. It also deals with coating materials and types and its properties. In the experimental part of the paper, the measuring and testing procedures are described and the test results are listed. Adhesi (…)
