In metal machining, regenerative chatter seriously affects tool life, part surface quality and cutting efficiency. To suppress generated during milling, researchers have proposed a variable spindle speed technique. But the previous VSS milling model is based on two degrees of freedom system (two-DOF). this paper, three-DOF suitable for thin-walled parts by introducing axial contact angle. The i...

The robotic grinding system for a thin-walled workpiece is multi-dimensional coupling composed of robot, spindle and the workpiece. In process, dynamic effect generated, while stimulates elastic vibration; spindle, as an electromechanical actuator, sensitive to vibration in form load fluctuations. It necessary investigate characteristics under well control system. Firstly, considering between w...
