CAD and FEM Modelling of Theoretical Roughness in Diamond Burnishing

Abstract Diamond burnishing is a widely used finishing machining that can have positive effect on both the roughness of cut surfaces and its stress state. This paper focused examination theoretical real machined by sliding burnishing. In determining roughness, surface structure created pre-burnishing cutting (turning) was also considered. Two different modelling methods were to obtain data: CAD-modelling finite element simulation. A method using CAD-based determine for turning processes. However, this previously developed model not directly applicable plastic deformation processes such as diamond burnishing, so principle Hertz theory normal contact elastic solids calculate penetration depth tool into workpiece. The 2D FEM simulations performed in DEFORM software. To validate applied methods, experiments performed, where values measured during with feed per revolution values. Based comparison data it be stated are well approximated data.
