surface roughness, polishing options, 3D roughness of the surface, polishing power.


The life and reliability of machine components or elements are affected greatly by the surface integrity. Machined surfaces by conventional processes such as turning and milling have inherent irregularities and defects like tool marks and scratches that cause energy dissipation (friction) and surface damage (wear). Ball burnishing has proved to be a highly effective mechanical finishing process of industrial workpieces because of the excellent surface roughness and fatigue performance that induces in treated components. This paper focuses on the examination of the influence of different burnishing parameters, such as number of passes (i), feed rate (f) and burnishing force (F). For plan and execute the experiments we use full factorial experimental design method by which empirical formulas can be created easily. The measurement of the surface roughness was executed with Altisurf 520 3D measuring equipment at the Institute of Manufacturing Science. The measured results were evaluated by the comparison of a special correlation formula to determine the optimal combination level of the different parameters in the given interval.
