Abstract
This paper aims to utilize finite element (FE) methods to predict the wear of dies and workpiece in cold rotary forging through systematically investigating the contact pressure and the contact slip distance. For this purpose, a 3D elastic-plastic FE model of cold rotary forging is developed using the FE code ABAQUS. Using this reliable 3D FE model, the evolution and the distribution of contact pressure and contact slip distance are investigated in detail. Consequently, a new insight into the wear that occurs at the surfaces of the dies and the workpiece is gained based on Archard's wear law.
