Notes:
In the car body stamping process, trim/blank die cutting edges are subjected to very hightribological loads that result in loss of tool material from both the punch and die cutting edges.According to Archard’s wear model, normal contact force and sliding distance directly affects thewear. Therefore, knowledge of the acting forces on local contact areas has a pivotal role towards theprediction of tool wear. This paper presents a finite element modelling approach to determining thecontact pressure distribution on the tool cutting edges during a trimming/blanking process.Characteristic areas on sheared edge profile, variation of punch force and high contact pressuresaffected areas have also been analysed
