Analysis of Individual Die Tonnage Using Multiple Tonnage Sensors for Multiple Operation Forging Processes

Qingyu Yang, Qiang Li and Judy Jin, Industrial and Operations Engineering Department, University of Michigan. This FIERF Graduate Fellowship Grant, with HHI Forging Operation Royal Oak and OG Technologies as industry partners, focused on advancing the usage of tonnage signals not only for press force monitoring, but by developing signal characteristics to detect variations in tonnage and correlate these to process and quality issues. The estimation of the source signals offers efficient monitoring and quality assessment capabilities of individual stations.
