• The deformation of low- and high-strength steels• Advanced types and high-strength steels• Controlling springback and friction• Troubleshooting production problems• What computer simulation (virtual forming) can do for you

The NewSheetmetal Forming

Technology

Today’s Need To Understand the Metal — Day 11. Changes in the Press Shop • Historical origin highlights today’sweaknesses• Treating sheetmetal forming as a system• Do you have a “Formability Engineer” onyour staff?• Broadening your concepts of howsheetmetal behaves• The “D” word must become your best friend2. A New View of Metals• All metals are alike and all are different• Proper metal identification is needed• Steels are getting stronger – 200 ksi Y.S. andclimbing?• Difference between elastic and plasticdeformation• Stresses that cause springback3. Sheetmetal Identification• Low-strength to high-strength range isgrowing• Low, high, ultra-high strength names aremisleading• The “Banana Curve” has been expanded• Forming rules demanded by Mother Nature4. Forming Sheetmetal• Forming failure or dimensional consistency?• Modes of bending• Pure stretching• Drawing (cup, deep, radial) 5. Strain Gradients• Defining strain gradients• Top ten reasons why strain gradients are badfor you• Sources of gradients

6. Surface Topography, Lubrication, Friction• Surface topography (roughness iseverything)• Measuring coefficient of friction• New rules for lubricant application• The new/dry barrier lubricants with a casestudy7. Tryout Time• Die engineering window versus mill steelcapability• Suggested tryout procedure to gather extrauseful data• Case studies8. Appendix: Sheetmetal Forming Definitions

New Metal Properties HelpMetalformers — Day 21. Sheetmetal characterization• Learn from press shop cartoons• Some concepts learned from Day 1• A taste of virtual forming (case study)2. Tensile Test and the Metal Properties • Properties are the key language ofsheetmetal forming• Properties from the tensile test and whateach controls• From Y.S., T.S., Total Elong. to Y.P.E., n, m, r,and more today3. Forming Limit Diagrams• Forming Limit Curve (FLC) is the edge of thefailure cliff • How to generate an FLC• The Forming Limit Diagram – FLC plus theseverity of the part• What the FLD tells you• Case study – Order Steel A or Steel B?4. Additional Sheetmetal Properties • Forming speed• Hardness testing• Cutting, shearing, blanking, punchingdamage• Simulative tests

• Thermal properties and tracking formingtemperature• Earing of deep-drawn cups5. Metal Types and Their Properties• Importance of properties• VD-IF, AKDQ (FS, DS, etc.)• BH and HSLA • Analysis of forming a 1977 all-steel HSLAfront bumper (case study)6. AHSS – Advanced High-Strength Steels• Two main groups: 1= constant strength, 2=constant formability• Understanding how and why Group 1 works• Understanding how and why Group 2 works• Other new types of AHSS • Some comparisons with aluminum• Stress-strain curves tell their story7. Virtual Sheetmetal Forming• What is it?• How it works: Inverse forming andIncremental forming• Outputs and benefits• Forming with a transparent die• Details on what is needed to operate theprogram8. Implementing New Ideas• Suggestions for implementing the newtechnologies• Some of the bumps in the road9. Additional Information on the Website• Some excellent free and other downloads

Presenter:Stuart P. Keeler, President, Keeler Technologies LLCStuart Keeler’s entire five-decade career has been dedicated to bringing science to the pressshop. Career highlights include his discovery of the Forming Limit Diagram and the developmentof Circle Grid Analysis. His metalforming experience includes 24 years at National Steel Corp. inDetroit and 12 years at the ThyssenKruppBudd Technical Center – a large Tier One automotivebody and chassis parts supplier conducting and managing sheetmetal formability research. For14 years he taught a three-day semiannual course in Understanding Sheetmetal Formability atthe University of Wisconsin Continuing Education Center in Milwaukee. For PMA, Stuartconducts a number of open seminars and in-plant training programs, and he is in his 16th year asthe Science of Forming columnist for MetalForming magazine. For the last decade he has beenTechnical Editor and contributor for the five versions of AHSS Application Guidelines forWorldAutoSteel. Version 5.0 was released May 14, 2014.
