W niniejszej pracy przedstawiono sposób modelowania 3D procesu wykrawania z uwzględnieniem krzywej linii cięcia. Symulację komputerową przeprowadzono dla przestrzennych stanów naprężeń i odkształceń wykorzystując metodę elementów skończonych. Otrzymano mapy intensywności naprężeń i odkształceń dla dowolnej chwili czasowej z uwzględnieniem nieliniowości występujących w procesie. Przedstawiono wybrane...
Grinding, embossing, burnishing, thread rolling, drawing, cutting, turning are very complicated technological processes. To increase the quality of the product and minimize the cost of process, we should know the physical phenomena which exist during the process. The phenomena on a typical incremental step were described using a step-by-step incremental procedure, with an updated Lagrange's formulation...
