During the past 20 years, stamping simulation has brought tremendous change to the way stamping processes are defined and validated, stamping tools are designed and built, and stampings are produced. Without state-of-the-art simulation tools, today’s complex stampings using high-tech sheet…

“If at first you don’t succeed, try, try again.” Systematic process improvement, as described in several previous posts (Adjusting complex process variables: Drawbead shapes, Virtual Tryout or Process Engineering?,What is passing?, In the rearview mirror, Infinitely adjustable presses, when should…

Springback of sheet metal stamped parts is a challenge faced by tooling suppliers and their customers; parts produced in stamping dies require significant effort in engineering and simulation to arrive at reasonable dimensional accuracy during process design. Conventional methods for…

The Stamping System

A recurring theme on this blog, so far, has been sources of variation in production that might not be apparent to engineers when defining, running, and evaluating a single simulation on any specific product/process design. Comments on the blog and…

When a closed section part is designed for manufacture, part shape, material grade, and wall thickness are often driven by the proposed hydroforming technology. Historically, suppliers dictate which process would be applied. Suppliers may specialize in one process over another;…

Numerical controlled (N/C) cushions have previously been the realm of large OEMs and Tier 0.5 stampers in their newer large presses. Until now, the technology has been out of reach for many Tier 1 and supply chain stampers. In the…

One of the most time-consuming and difficult-to-predict aspects of die build and tryout for progressive dies is the development and validation of the blanking cuts. Blanking is often a series of cutouts used to trim the flat coil material and…

Has this happened to you? The sales department wins a job for process engineering, die design, tool build, and stamping production. Upon review of the bid package, you note the inclusion of a “quoted blank.” Immediately that blank has you…

In simulation, there is ongoing effort to prove who can claim to be the best at “virtual tryout.” Product brochures and websites promote software solutions that “bypass soft tooling” and “minimize die tryout.” While these are certainly desirable goals, perhaps…
