Kurzfassung

This paper presents an experimental analysis of tool vibrations for instationary milling processes. This analysis is necessary to validate a time-domain simulation system for the general milling process. For this, the axial and radial immersions are changed during the milling process. This leads to an instationary process with varying engagement conditions. The tool trajectories are measured along the running process. The analyses of the recorded trajectories and the machined surface show different kinds of bifurcations and how a milling tool tunes from one vibration orbit into another one. Besides, the analysis process, the experimental setup for measuring the tool trajectories and the surface quality is discussed in this paper.
