Abstract

In micro/nano milling, the accuracy of tools in high-speed motion and the correspondingly final milled precision are greatly affected by the holder. Shrink-fit tool holders have high precision in principle to assure micro/nano milling since there is no medium between the holder and the cutter. Aiming at micro/nano milling, this study provides a systematic modeling and analysis process for shrink-fit holders. The heating and cooling rules of the shrink-fit holder are analyzed for various cases to study the deformation and stress fields. It shows that the clamping hole size is the critical factor affecting the insert of the tool and the material failure possibilities. The outside size of the tool holder has limited effect on the heating and cooling processes. The clamping torque is large enough for even heavy-duty micro/nano milling applications. Based on the models and analytical results, a systematic design procedure for novel shrink-fit tool holders is proposed.
