A CAE/CAI Integrated Method for Sheet Metal Forming
With the development of computer technology, Computer Aided Engineering (CAE) and Computer Aided Inspection (CAI) are more widely used in stamping products for design and manufacture, but there is a lack of link between each other. On the one hand, results of CAE analysis are not effectively used and evaluated; the other hand, single CAI is not able to analyze reasons for wrinkle, crack, or springback in stamping products. To compensate these shortcomings, a CAE/CAI integrated method is established to ensure information sharing between of them, which is helpful for guiding the design of sheet metal forming. By this method, the feasibility of sheet metal forming is analyzed and forecasted, and the results of deformation are effectively assessed by 3D comparison, 2D comparison and GD&T inspection. And ultimately the superiority of CAE/CAI Integrated method is proved by case study.
