Hotel & Travel Information

Preventing future problems and troubleshooting existing problems in today's stamping plants requires greater stamping process knowledge. The link between inputs and outputs isn't as clear as many think, increasing the need for detailed understanding of the variables involved. This course discusses the key inputs and outputs associated with sheet metal stamping, including important elements for controlling the process and making it more robust. The course reviews sheet metal characteristics and their application, especially from a formability standpoint, using many automotive-related examples. Common issues such as springback, dent resistance, and process differences among mild steel, high strength steel, bake hardenable steel, and aluminum are discussed. Stamping die types and functions, in particular the types of dies used in draw forming, are explained. Mechanical presses and lubrication are briefly discussed as other variables in the process. Other processes, including tube and sheet hydroforming, and progressive dies are covered in less detail.

Learning Objectives
By attending this seminar, you will be able to:

  • Describe steps and elements of the stamping process
  • Identify common grades of sheet metal and their applications
  • Specify key mechanical properties and their relationship to product quality
  • Identify important inputs and outputs of the stamping process
  • Describe important aspects of process control
  • Read and interpret sheet metal strain analysis and forming limit diagrams

Who Should Attend
Anyone who wants to know more about sheet metal stamping, from new hires in the industry, to product design engineers who design sheet metal parts, to manufacturing engineers, supervisors, and others working at a stamping plant, will benefit from this seminar. Those with plant floor experience who are lacking a solid understanding of the how's and why's will also benefit.

Instructor(s): Edmund Herman
Mr. Herman is President of Creative Concepts Company, Inc. Prior to establishing his consulting business, Mr. Herman worked for General Motors Corporation where he was responsible for new process development in the areas of draw die development for sheet metal stamping dies, mold development for sheet molding compounds, and pressure die casting dies and processes. He was instrumental in the shift from physical plaster developments to total CAD design of sheet metal draw die developments. Mr. Herman is also an experienced instructor and served as the Education Director for the Society of Die Casting Engineers (now the North American Die Casting Association). He has taught continuing education courses in die casting, stamping and injection molding through Oakland and Wayne State Universities. Mr. Herman is a registered professional engineer in the state of Michigan and has a Bachelor of Science in Industrial Engineering from General Motors Institute and a Master of Science in Industrial Engineering - Operations Research from the University of Michigan.
