Experimental Investigation on Growth Mechanism of Machining Error Caused by Vibrations of End Mill

抄録

The purpose of this study is to establish a method of estimating, in real time, the machining error caused by vibrations of the cutting point of an end mill. The vibration displacement at the shank of the end mill and the dynamic cutting force were measured during cutting tests while spindle speed was increased from medium to high. It was found that the vibration displacement, which was calculated by convolution of the dynamic cutting force and the impulse response of the tool system, showed a good agreement with the measured vibration displacement in all spindle speed range.
