On Analysis of Orthogonal Cutting Mechanism with a Pb-Sn Alloy

概要

論文の詳細を見る
The purpose of this paper is to verify how the behavior of work-softening with a Pb-Sn alloy affects the cutting mechanism, applying experimental methods on the basis of slip line solutions. Also experiments are performed on conventional orthogonal cutting and in addition, on cutting with the chip-pulling technique and by high rake tools or by a double rake tool. As one of the results, it is considered that the free surface boundary condition for slip line solutions is fulfilled in the smooth cutting by using high rake tools, under the experimental conditions. The experimental results are applicable to the high speed cutting, when work-softening is expected to contribute to teh cutting mechanism.
