Dependency of Gear Honing Machine Processing Accuracy on Machine Vibration

Abstract

In recent years, machine tools are required to be compatible the processing accuracy with the speed. However, the accuracy is generally decreased in case the processing speed is increased by the vibration. In this study, we then investigated the relationship between the processing accuracy and the vibration of a gear honing machine. Many gears were processed under various processing condition and the vibration acceleration were measured during the machining process. After then, we considered the relationship between various vibration characteristic such as gear order vibration and the accuracy. As the result, the first order vibration of the gear rotational speed was found to correlate with the accuracy and a multiple regression equation using the vibration could be proposed to express the accuracy.
