Aiming at the characteristics of forging,stamping and other products with complex shapes and many process constraints,an advanced modeling method based on CAD software is studied.Through fea-ture extraction,parametric modeling and finite element integration and other technologies,the modeling ef-ficiency and quality are improved.The study shows that the use of advanced technology can realize the effective description of the holistic characteristics of forming products and meet the subsequent engineering analysis needs.It is verified by examples that the CAD modeling method of formed products based on fea-ture recognition and parametric technology has high modeling efficiency,good quality and optimized simu-lation speed.
