This paper studies a method of computer aided stamping--geometric modeling method comprehensively. This paper works over the signified technology of geometric modeling by pure homogeneous deformation of the theory for large deformations, which include the plot off mesh unit, selection of segmentation line and mapping. And It investigates a deep drawing of paraboloid stamping part and forecasts the geometry, dimension, strain distribution on a sheet rough successfully and well.
