Stability Of The High-speed Milling And Machining Distortion

The high-speed milling process is a complicated dynamic system. When milling thin-walled components of aluminium alloys, a phenomenon commonly encountered is chatter. The chatter is a vibration between workpiece and cutting tool during the milling process, leading to poor surface finish of the workpiece and low efficiency of the machine tool. The chatter in milling process is a main question for discussion in machining industry at all times. The research of the chatter refer to many jobs. In this paper, some research of the chatter has been done. It includes several points such as nonlinear theoretic model of the chatter and simulant experiment based on this model using the MATLAB/SIMULINK.When milling workpiece with the character of thin-wall, a another phenomenon commonly encountered is the deformation of the workpiece, leading to poor dimensional accuracy. In this paper, the deformation of thin-walled component of aluminium alloys is studied by simulant analysis based on FEM using the ANSYS, mainly considering the effects of cutting force and remnant stress.
