Abstract

Recently years, the resuslt of researches on new cutting tools have been applied more and more in practically. Especially, coated cutting tools contribute more than 80% on the world of cutting tools and are applied largely in production, productivity in machining field has increased considerablly, high machining productivity achieves with considerable advances of equipments as well as new technologies. In there, we can’t help telling the kinds of new cutting tool which are born. However scientific researches relate to appreciate and compare machining productivity for different materials very little, it hasn’t been got more reseaches. Therefore, to appreciate cutting material productivity of different cutting tools. We must appreciate at the same condition of tool life. For this purpose, we must define the relation between tool life and cutting condition first. Moreover, this appreciation of cutting productivity will solve two problems such as on the one hand serving production in practice, on the other hand serving training. Accordingly, in this article, we presentexperimental planning method of Box and Hunter to appreciate cutting material productivity of coated tool.
