Process Machine Interactions in Micro Milling

In this chapter, both analytical and experimental studies on the process stability of micro milling are presented. The investigations are carried out in order to improve a comprehensive model, which describes interactions of the dynamic cutting forces and the dynamic machine tool behavior including the end mill. Dominant chatter frequencies at different operating points are determined by analyzing the process forces, acoustic signals as well as optical measurement signals. Results are documented and discussed by means of stability lobe diagrams. The findings are confirmed by analyses of the milled surfaces. Finally, some suggestions for improving the parameter identification are given.
