Kurzfassung

This paper presents a geometric model for the construction of the surface structure, which is produced by vibrating milling tools. The tool trajectories, which are calculated by an existing time domain simulation of the dynamic milling process, are analyzed and converted into a model of the machined workpiece. For this, a geometric model is applied, which can be visualized photorealistically and analyzed in order to measure the surface location error and roughness. Hereby, the geometric appearance of chatter-marks is explained even for helical milling tools and the simulation system is verified by the comparison of simulated and real machined workpieces.
