Problem
1. What is so special about sheet metal parts that they cannot be modeled using the conventional features modeling approach?
2. Why should we not use the assembly modeling approach to create welded parts as assemblies?
3. Define sheet metal. What distinguishes it from foil or plates?
4. Select one of the sheet metal processes (punching, rolling, stamping, etc.), and describe how the process works. Provide a report of the process details with sketches.
