Selecting Optimum Interference Fit in Tool Assemblies Using Die-Press & Simulation Software

摘要

The tooling that is used in cold forging is subjected to very high stresses due to the high strength of the metal when deformed at ambient temperature. In order to withstand this high pressure exerted by the deforming metal, in some applications, the tooling is made of multiple components that are fitted together using interference fit. Design of these tool assemblies is very critical as it determines the life of the tool components.
