For the continued growth of tube-hydroforming, better methods for creating and validating springback compensation are essential. Upcoming vehicle programs forecast increasing use of Advanced High-Strength Steel along with more tube-hydroformed parts.  The release of AutoForm-HydroDesigner2016 represents the first commercial solution…

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…
