An Overview of Diagnosing and Controlling Assembly Variation of Sheet Metal Parts

This paper reviews the advancement in the fields of tracking, diagnosing and reducing dimensional variation in sheet metal parts assembly. Especially, the problems in the process of car body assembling, including SPC, tolerance analysis and synthesis, measurement of variation in geometric accuracy, mechanism of geometric variation and their applications to error control are discussed. It shows that the tolerance analysis and synthesis method based on physical and geometric nonlinear model may be a promising way to find out the root causes of dimensional failures.
