Historical process capability data (PCD) is commonly used during product design. Such data can be stored in a formal database known as a process capability database (PCDB). PCD is primarily used during product design to allocate tolerances or forecast and

The paper analyses a model of smoothing ball-burnishing which takes into account the mechanical properties of the workpiece, the geometry of the workpiece-tool contact area as well as the stereometry of the machined surface. It allows the determination of the dependence of the tip displacement of the machined surface asperities on the burnishing tool pressure. In the model-based research the effect of the particular parameters of the burnishing process on the tip displacement was defined. The optimum value of the displacement and the pressure it takes under various burnishing conditions were calculated. The analysis results were verified experimentally.
