| Abstract: | The autobody assembly process is one of the most important processes of automobile manufacturing. In this paper, a new approach named M-CII control chart is presented. By this approach, the CMM measurement data of the Body-in-White is categorized according to their geometrical accuracy, and both variance and mean deviation are considered simultaneously. It can be used in quality control and fault diagnosis for autobody assemble process. |
