Improve HSS part quality before die tryout
This C-pillar reinforcement is manufactured by deep drawing, cutting, and flanging (on left). Die faces for the deep-drawing stage, including the binder, addendum, filled surfaces, and part, can be developed using simulation software (on right). The use of high-strength steels (HSS) and...

3D CAD modeling of sheet metal parts
Figure 1a This is the starting point for the pedestal design. The main variation in sheet metal modeling techniques is when to let the 3-D CAD system know that the part is to be treated as sheet metal. With the 3-D CAD tool that I use most often, I have three basic options: Create the... Read more...

Essential CAD: A starting point
My fantasy is to have my thoughts telepathically linked to a computer—resulting in smarter and faster designs. It would be even more helpful if the computer would dream up solutions for me. Now that would be computer-aided design! However, mind reading is a little beyond what even the... Read more...
