Algorithm Development and Application of Spring back Compensation for Sheet Metal Forming
並列摘要
The aim of this research is to develop an algorithm to solve difficulty associated with spring back error in sheet metal forming. Spring back can be considered as a dimensional change which happens during unloading, due to the occurrence of primarily elastic recovery of the material. The die surface compensation is needed to obtain the accurate product due to geometrical deviations caused by spring back. Die-compensation simulation enables companies to increase competitiveness by increasing product accuracy and reducing the number of errors in sheet metal forming process. The proposed algorithm combines two methods of die compensation; Displacement Adjustment (DA) and Spring-Forward (SF) methods. Both are based on iteratively comparing the deformed shape with the target.
