The research was made on the reason for the hidden flaw produced on an inner door panel based on the analysis of material properties and the CGA grid test; and the dif?ferent improvement measures were put forward for the hidden flaw in the different posi?tion. The practical production shows that the debugging scheme proposed according to CGA grid method was feasible and effective, and improved the forming safety.
