Simulation predicts presswork spring-back
Springback in metal stamping is a major problem, particularly for those manufacturing automotive parts from high-strength steel.
Simulation allows transparent formability analysis
The PAM-STAMP 2G family of stamping software has been expanded by providing within CAA V5 a new simulation application, which performs Transparent Formability Analysis.
Advanced Cam relies on Pam-Stamp 2G simulations to provide customers with 'right first time' tool designs for automotive components in order to run production with a minimum of manufacturing risks.
This cost-efficient, sheet-metal Stamping simulation tool, developed by ESI Group, covers the entire tooling process from quotation and die design through formability and try-out validation.
Pam-Stamp 2G includes the modules Pam-Diemaker for rapid die creation, Pam-QuikStamp for rapid Stamping evaluation and Pam-AUTOStamp for forming-process validation, quality and tolerance control.

Sheet metal stamping simulation software
ESI Group has released Pam-Stamp 2G 2004, a new version of its sheet metal stamping simulation software, which offers web-based reporting tools and advanced parametric re-engineering.
Multiphysics software is more accurate
The V2007.2 release of multiphysics software CFD-ACE+ from ESI Group has significant product enhancements and more than 50 maintenance requests offering increased accuracy.
The latest progress in the software lies in the possibility to predict springback accurately, allowing effective die compensation to correct this effect.
Using Pam-Stamp 2G, Advanced Cam modifies the tooling geometry at an early stage of the design phase in order to compensate for the effect of springback.
"The accuracy of the simulation from Pam-Stamp 2G and the precision of the graphical results make it the foundation of my business".
"We upgraded to Pam-Stamp 2G in January 2004, after five years of using the previous version, and found that, among other benefits, it runs much faster than the previous version".
"For example, a simulation that once took 10 hours to process now only takes half the time".
"Springback calculations run in minutes instead of hours".
"This enables us to modify tool design and achieve high-quality die tooling of automotive components," says Eric Wilhelm, owner of Advanced Cam (based in Utica, Michigan).
"Springback is a major problem in production, particularly with high-strength steel, as the part's shape after springback may not be within tolerance and could be unsuitable for the intended application".
"The amount of springback depends upon the distribution of stresses at the end of the forming, which in turn results from the properties of the material and the geometry of the part," adds Dave Ling, Stamping Product Manager, ESI Group.
"Using Pam-Stamp 2G, Advanced Cam modifies the tooling geometry to compensate for the effect of springback." With Pam-Stamp 2G, Advanced Cam has been able to reduce the design cycle whilst increasing component quality and accurately predicting wrinkles, splits and springback.
Through the use of simulation, manufacturing risks have been minimised, engineering changes and downstream problems have been reduced, and processing time is cut back with the MPP (Massively Parallel Processing) version.
