Advanced theory and technologies,parametric modeling,database management,finite element method and metal forming control,were applied in our study. Parametric pass design CAD system,whole process thermo-mechanical numerical simulation and optimizing CAE system and CAM system of rolls for section steel rolling were developed. All of the systems above were integrated based on the idea of pass parameterization. Thus,a CAD-CAE-CAM system of dig-ital section steel rolling pass design and manufacturing with the database transmitting directly was achieved. The efficien-cy and accuracy of developing complex section steel were considerably improved and the problem of quality and preci-sion during developing and manufacturing were effectively solved. High precision complex section steel rolling digital technology has been successfully applied in high precision rail rolling and pass optimizing practically,as well as in devel-oping a gantry section steel (J-shaped steel).
