R&D Update: Examining lubricant performance in forming of AHSS

February 5, 2015

By: , ,

Lubrication plays an important role in stamping, as it reduces friction at the tool-workpiece interface. Reducing that friction also reduces die and tool wear in large-volume production, which in turn increases tool life. It also allows smoother flow of the sheet material into the die cavity and...

The pursuit to be the best value-added supplier

January 29, 2015

By:

Waukesha Metal Products, a metal fabricator and metal former based in Sussex, Wis., wasn't going to survive in the long run being a simple stamper of simple metal parts. It needed to reinvent itself and constantly look for ways to evolve if it were to grow and improve its chances of success in the face of more demanding customers. Its in-house knowledge and talent, investment in capacity, and contributions to the overall manufacturing cause are improving its long-term viability. They also have helped the company earn the 2015 Industry Award from The FABRICATOR.

Optimal tooling approaches for punching AHSS

March 3, 2014

By:

The tried-and-true approaches that worked well to stamp first-generation steels are not as effective for stamping advanced high-strength steels (AHSS). Tests were conducted to determine optimal punch-to-die clearances, shear angles, and punch angles. Test results indicated that 12 to 15 percent punch-to-die clearances and -15- to +15-degree shear angles provided the longest punch and die life, and a 7-degree conical shear angle created the smallest burr growth.
