Side-Milling-Force Model Considering Tool Runout and Workpiece Deformation

With the development of Industry 4.0, hard-cut materials such as titanium alloys have been widely used in aerospace industry. However, due to poor rigidity alloy parts, deformation and vibration easily occur during cutting process, which affects accuracy, surface quality efficiency part machining. Therefore, this paper, tool runout workpiece are introduced into milling process flat-end mills. Based on tool’s hypocycloid motion, a geometric parameter model is established, undeformed thickness obtained considering deformation. Finally, force for side-milling thin-walled parts was established. The accuracy verified through experiments. error proposed far less than that traditional basic method. maximum method 87.09%. only 66.54%. results show can provide more accurate prediction.
