Modellierung von Größeneinflüssen bei der Gratbildung

Size effects play a decisive role in burr formation. To characterize them, different burr parameters, such as the hydrostatic bowl or the burr shear zone, have been conducted. Both thermo-mechanical quantities in the burr shear zone and the hydrostatic bowls do significantly depend on scaling effects. This result bases on the development of software for a better analysis and unterstanding of the burr formation process. Significant size effects due to the variation of tool chamfer and feed rate on cutting and thrust forces have been determined.
