Abstract
In this paper, a face-milling cutter is proposed and manufactured to improve a cutter’s dynamic characteristics. The proposed cutter, comprises double step blades, and is designed to give better stability in terms of vibration and to suppress the possibility of abrupt wear and chipping. Vibration experiments with the conventional type and the proposed cutter were performed, and the results showed that the vibration amplitude in the time domain and the peak value in the vibration spectrum in the frequency domain are considerably lower for the proposed cutter than for the conventional cutter. In addition, the validity of a cutting dynamics model, which can effectively predict the cutting dynamics on the machine–tool–workpiece (M–T–W), was examined by the vibration experiments.
