| Research Abstract |
Practical chatter avoidance method for milling is proposed, and the feasibility of development of the next generation machine tools, which is equipped with the automatic chatter avoidance functions, are discussed. In the proposed method, the chatter types are distinguished by measured chatter vibration while machining, then, the suitable chatter avoidance condition is estimated. Consequently, the cutting condition can be improved and optimized by iterating this step. Meanwhile, proposed method do not need either measuring transfer function or sophistication and skills to calculate stability/allowable limits in chatter vibrations, which are required in the conventional methods. It was confirmed that the suitable chatter avoidance conditions can be predicted and optimized by the proposed method.
