Definition of edges in correlation to abrasive flow machining as a finishing process

The transition of two geometrical features, like a radius or edge, is one part of the geometrical properties of a workpiece. For abrasive flow machining as a surface finishing process the characterization of the edge is important. Different processing parameters of the abrasive flow machining process are compared to geometrical properties within a test series. Based on 3D measurements and a datum system first results of an edge definition are derived. A histogram of radii provides a simplified method to separate the geometrical features to define the start and end of the edge.
