Development of next generation machine tool to enable automatic chatter avoidance

提出了实用的铣削防抖方法，并讨论了开发具有自动防抖功能的下一代机床的可行性。在该方法中，通过测量加工过程中的颤振振动来区分颤振类型，然后估计出合适的颤振避免条件。因此，通过迭代这一步骤，可以改善和优化切割条件。同时，该方法既不需要测量传递函数，也不需要计算颤振稳定性/允许极限的复杂程度和技巧，这在传统方法中是必需的。仿真结果表明，该方法可以预测和优化合适的防抖振条件。

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.
