A Study on Chip-breaker

概要

論文の詳細を見る
Limiting condition of chip breaking with a parallel type chip-breaker has been found to be determined by only the follwing three items : the radius of chip flow circle, the material to be cut and the thickness of chip. The larger the radius of chip flow circle, the steeper the slant of a chip-breaker and the thinner the chip, the smaller was the force acting on a chip-breaker due to chip curling. The yield stress of chip was found to become about twice that of the same material before cut. From these results, a simple method for finding the optimum shape of a chip-breaker was established. In this method, a proper radius of chip flow circle is found directly by measuring the thickness of chip which is obtained under the given cutting conditions and by the use of a diagram presented in this paper.
