Numerical Modeling and Simulation of the Movable Contact Tool-Workpiece and Application in Technological Processes

Leon Kukielka, Agnieszka Kulakowska, Radoslaw Patyk

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. The technological processes are considered as geometrical and physical non-linear initial and boundary problems. The finite element method (FEM) and the dynamic explicit method (DEM) were used to obtain the solution. The application was developed in the ANSYS/LS-DYNA system, which makes possible a complex time analysis of the physical phenomena: states of displacements, strains and stresses. Numerical computations of the strain and stress have been conducted with the use of methodology which requires a proper definition of the contact zone, without the necessity to introduce boundary conditions. Examples of calculations are presented.
