Quantitative Analysis and Mathematical Model for Spindle Vibration of the End-Milling by Design of Experiment

실험계획법을 이용한 엔드밀 가공시 주축 진동에 대한 정량적 분석 및 수학적 모형

End-milling have been widely used in aircraft, automobile part and moulding industry. However, various working factors such as spindle speed, feed rate and depth of cut in end-milling have an effect on spindle vibration. There it is demanded the quantitative analysis of spindle vibration in order to get the optimum surface roughness. This study was carried out to analyze an influence of working factors on spindle vibration by design of Experiment. The results are shown that mathematical model of regression equation for an influence of working factors on vibration acceleration of spindle in end-milling by regression analysis is presented.
