Investigating Stability Limits in High Speed Milling of Titanium Thin-Walled Parts

The main objective in machining processes is improving the productivity and Efficiency of the process. Nowadays, high speed machining is used to meet the market needs. However, in high speed milling the prediction of stability of machining is the key issue. In this study, the cutting forces for low immersion endmilling are predicted by an efficient dynamic force modeler. In addition, a geometric solid modeler (ACIS) is used in order to model the part, compute the chip load and update the part as the tool removes the material. In this way, the interaction between tool and part is accurately simulated. Finally by using the developed software, the stability of the process is investigated and stability limits are proposed.
