  • A Method and Device for 3D Recognition of Cutting Edge Micro Geometry
    Publikacja

    - Drvna Industrija - Rok 2014

    A very useful method was successfully applied in the investigation of tools for machining wood and wood based composites. It allows scanning of the cutting edge micro geometry in three dimensions and reproducing it in a virtual space as a 3D surface. The application of the method opens new possibilities of studying tool wear by scanning, including the calculation of volume loss and other analysis of tool wedge geometry along and...

  • A New Microwave Ceramic – Polymer Composite with 0-3 Connectivity

    Goal of the present research was to fabricate and study two-phase BiNbO4//PVDF composites with 0-3 connectivity. Such composite consists of there-dimensionally connected polymer matrix loaded with dielectric ceramic particles. In the present case BiNbO4 powder acted as an active phase (dispersed phase) whereas polyvinylidene fluoride (PVDF) acted as a non-active (passive) phase (matrix). BiNbO4//PVDF composites with the volume...

  • AN INNOVATIVE APPROACH TO PREDICTION ENERGETIC EFFECTS OF WOOD CUTTING PROCESS WITH CIRCULAR-SAW BLADES
    Publikacja

    - WOOD RES-SLOVAKIA - Rok 2014

    In the classical approach, energetic effects (cutting forces and cutting power) of wood sawing process are generally calculated on the basis of the specific cutting resistance, which is in the case of wood cutting the function of more or less important factors. The aim of the paper is to present a new calculating model using the application of modern fracture mechanics and to compare cutting parameters of native beech, Bendywood...

  • An Innovative Approach to the Forecasting of Energetic Effects While Wood Sawing
    Publikacja

    - Drvna Industrija - Rok 2014

    In the classical approach, energetic effects (cutting forces and cutting power) of wood sawing process are generally calculated on the basis of the specifi c cutting resistance, which is in the case of wood cutting the function of more or less important factors. On the other hand, the cutting forces (power) problem may be tackled with an innovative, up-to-date fundamental analysis of the mechanics of sawing based on modern fracture mechanics....

  • Analiza skupień jako metoda wspomagania decyzji zakupu urządzeń prądu stałego do spawania metodą TIG
    Publikacja

    W pracy podjęto zagadnienie wspomagania decyzji zakupu odpowiedniego spawalniczego źródła prądu. Zaproponowano rozwiązanie problemu z wykorzystaniem metod analizy skupień. Przedstawiono wyniki klasyfikacji 69 urządzeń prądu stałego do spawania TIG metodami Warda i k-średnich dla odpowiednio dobranego i przygotowanego zestawu cech diagnostycznych. Na podstawie wyników uznano, że analiza skupień może być skuteczną metodą wspomagania...
