페룰의 무심 연삭 가공시 실험계획법 및 회귀분석 적용에 관한 연구

The surface roughness in centerless grinding is mainly affected by the many process parameters. For decreasing the surface roughness, the control of grinding machining parameters is very important. This paper deal with the analysis of the process parameters such height of center, tilting angle of the regulating wheel, speed of regulating wheel, developed based on factorial design and regression model. The effect of grinding parameters on the surface roughness was evaluated the utilization of the regression analysis was evaluated with constraints of the surface roughness.
