Now Writing For MetalForming Magazine!

I’m now writing the monthly Science of Forming article for Metalforming Magazine – it’s a great honor to be taking over from Dr. Stuart Keeler.

See my first article, The More You Know, on page 36 at http://metalformingmagazine.com/magazine/digital-issue/?/2017/Dec

Optimizing sheetmetal flow to form a stamped part requires understanding the interaction between the sheetmetal, surface characteristics and tooling. Consider where we were in the 1970s. Back then, we could choose between seven grades of sheet steel. Most of the steel used on cars did not contain a galvanized coating. Lubrication for many deep-drawn parts consisted of a paste made from animal fat. And the tooling material choices for large stampings? With apologies to Henry Ford, you can have any material you want, as long as it’s D2. If the surface wasn’t up to the desired quality, there was always Bondo and a few more layers of paint. Using just trial-and-error could produce an acceptable part, given that there were a limited number of variables to master and the fact that a threshold for “sufficient quality” took comparatively less effort to achieve.

This sounds like ancient history. But is it?

About the Author:

Danny received his Bachelor of Science degree in Materials Science and Engineering from the Johns Hopkins University in Baltimore, MD, and a Master of Science and Doctor of Philosophy degrees in Materials Engineering from Drexel University in Philadelphia, PA. While at Drexel, Danny held engineering and research positions with the David Taylor Research Center (Annapolis, MD) and Hoeganaes Corporation (Riverton, NJ). After receiving his Doctorate, Danny started at the LTV Steel Technology Center (Independence, OH), where he was a member of the Customer Technical Center, focused on customer-based problem solving in the areas of corrosion, formability, and surface contaminants. He then transferred into the Automotive Development Group, focused on formability analysis and training; materials selection and optimization; tooling development and production launches for new vehicle programs; customer materials & manufacturing cost reduction efforts; forming/denting/structural computer simulation; and technical awareness and communications with the automotive manufacturers and their Tier One / Tier Two companies. Danny's first position in the ADG was as the engineer responsible for all transplant accounts, and then moved to having responsibility for the Ford Motor account, before being promoted to the Group Manager. During his time with LTV Steel, Danny was active in AISI and Auto/Steel Partnership activities, serving as Chairman of the Standardized Dent Resistance Test Project as well as participating in other committees. Danny is the founding member of Engineering Quality Solutions, Inc. Danny has over a dozen publications and is a member of ASM International, SAE International, and is the President of the North American Deep Drawing Research Group (www.NADDRG.org).
