Shrink-fit chucks are often used in high speed milling processes as they offer high torque transmission and low eccentricity due to their symmetric design. In some cases the milling cutter slips out of the shrink-fit chuck during high speed milling processes. This phenomenon, called tool extraction, is an unexplained problem with no repeatability so far. In this paper, experimental investigations such as SEM and residual stress measurements on the clamping surface of shrink-fit chucks affected by tool extraction are presented as well as a mathematical approach which aims on the prediction of failures due to process machine interaction. Within the mathematical approach a finite element model of tool and tool holder is coupled with a cutting force simulation in order to compute the resulting stresses in the interface of those components.
