Abstract
This paper studies the deformation of a thin wall during milling process. First, cutting experiments are presented to investigate the influence of the workpiece width on its deformation and the cutting force. Then, this paper presents a FEM-based model to simulate the deformation of thin-wall workpiece during milling process. With a tool rotation, cutting force is distributed along the helical cutting edge, and the workpiece deformation is calculated at each time interval with tool rotation. The simulated result is compared with a simpler model where a constant cutting force is uniformly distributed on an oblique line representing the material removal by a cylindrical tool.
