...Abstract Abstract This chapter addresses the issue of die failures in hot and cold forging operations. It describes failure classifications, fatigue fracture and wear mechanisms, analytical wear models, and the various factors that limit die life. It also includes several case studies in which...

... ). Estimation of Tool Wear A study by Meng ( Ref 16.9 ) showed that there are more than 300 equations to predict tool wear, each of which is a correlation of several parameters and is derived from various wear tests. Among these, the Archard wear equation (Eq) is commonly used for modeling tool wear...
