歯車加工機の振動寄与分離技術の基礎検討

抄録

In recent years, machine tools are required to reduce their work time by increasing the processing speed. However, this transition tends to decrease the processing accuracy due to the vibration. Therefore, understanding the vibration characteristic of the machine is important to be compatible the speed with the accuracy. In this study, we then attempted to know the main input force and the transfer path of a simple gear processing machine model by using a transfer path analysis. The input force was estimated by employing the transfer function and the vibration at the operational condition. In addition, the contribution was calculated by multiplying the estimated input force with the transfer function. Through the verification in which the input force and transfer function were modified, the method was clarified to be able to obtain the contribution well.
