A spring cutting tool, which is used for finishing of metal surface, is one of the most typical elastic tools. However, there are very few reports about the cutting characteristics of spring cutting tool. In this paper, the residue of cut, the relationship between pre-determined depth of cut and actual depth of cut, and so forth are investigated under the repeated cutting by the use of the simplified spring tool as cantilever-type.
The main results are as follows :
(1) At the same number of cut, the accumulated actual depth of cut of large rake angle is larger than that of small one.
(2) The residue of cut is approximately in agreement with the edge displacement in the cutting-beginning-point.
(3) The residue of cut does not depend almost upon the rake angle, but upon the relief angle.
(4) The results of the experiments agree approximately with the analysis.
