Modelling of tooling wear in trim dies for AHSS
thesisposted on 2009-01-01, 00:00 authored by Reza Rafiee
Using Advanced High Strength Steels (AHSS) in forming and cutting dies generates higher loads in tools. Tool wear is an issue when applying AHSS. This study investigates the effect of process parameters such as clearance, material properties and punch/die bluntness on contact pressure values and tool wear. Some desirable process parameters that minimise wear have been found.
