Development of the Indexable tool for high-feed cutting suitable for the high-efficiency cutting

Abstract

To reduce the risk of tool breakage in high-efficiency machining, the shape of the cutter body was studied using structural analysis. The structural analysis was performed using finite element analysis simulation software MSC Nastran 2019 from MSC Software, and was evaluated in terms of Mises stress. As a result, it was found that setting an appropriate angle at the radial side of the insert near the restraining surface had the effect of reducing the stress on the cutter body when a cutting load was applied. The angle is between 30° and 45°.
