Product Design for Sheet Metal Stampings - 16 Hours

This advanced practical course is a tool-maker and stamper's perspective of product design. The goal of this course is to highlight the "true cost" of part features and part tolerances. Designers will be shown just what can and can't be made using the metal stamping process as well as the process steps needed to make the feature. Alternate design features will also be explored.

Topics Include:

The effects of material selection R And N Values Grain Anisotropy Strain Distribution Commercial Names Yield Strength Plain Carbon Steels High Strength Steel Bake-Hardenable Steel A.H.S.S. - Dual Trip, Complex Phase Stainless Steel Aluminum Anisotrophy / Grain Drawing or stretching? Understanding The Difference Depth Of Forms Blank Development Solid Forming Understanding Drawing Ratios Defining Draw Ratios Calculating Blank Size Calculating Draw Reductions Risking Compression / Ductility Fractures

Product Design for Formability - 16 Hours

This practical course focuses on product design features from a die engineer's perspective. All too often stamped products are designed with features that are very costly or extremely difficult to make. Although these features and tolerances are sometimes necessary, often the part design can be changed and result in lower tooling and part costs. This course is designed for those with good product design skills.

Topics Include:

The Effects Of Material (Coil) R And N Values Grain Anisotropy Strain Distribution Commercial Names Yield Strength Plain Carbon Steels High Strength Steel Bake Hardenable Steel A.H.S.S. - Dual Trip, Complex Phase Stainless Steel Aluminum Anisotropy / Grain Draw Ratio Versus Product Design Drawing Versus Stretching Stretch Distribution Calculating Reductions For Costing The Effects Of Cold-Working The Metal
