Users of the unguided vibratory finishing process are facing a high economic risk due to smaller batch sizes and shorter product life cycles, which have led to a major in-crease in set-up costs. In this thesis, a heuristic explanatory model is presented, which enables a more efficient process design based on the knowledge of the trans-fer behavior of the work bowl acceleration to the acceleration of the abrasive media and the workpiece as well as the resulting contact force and relative speed.
