Study on the Testing Method of Cemented Carbide Tool : On the simple Testing method for the Tool Failure

Abstract

The ordinary testing methods of carbide tool are apt to be only hardness test of carbide, in spite of consuming many time and material. In this article, however, we report that the two fundamental causes of carbide tool failure, "chipping" and "cratering", are accelerated independently of each other by a moderate intermittent cutting and a high feed cutting respectively. Applying this principle, we can test the true value of carbide tool simply and select easily a suited grade for any given job.
