BEARING TOOLS MACHINING AND NEW EXPERIMENTAL EXPRESSION OF DURABILITY DEPENDENCE FOR SINTERED CARBIDE CUTTING

Abstract

Durability of the cutting tools is very complex process that is influenced by more factors. On the base of outputs and results these experiments can be completely described the most important elements acting on the resulting durability of a cutting tool. The technical science defines the basic method for determining durability of the cutting tool according to results and knowledge F. W. Taylor. This paper describes how to create and analytically express new durability dependence for sintered carbide cutting tool on the base of vc-VB dependence. This dependence consists from vc - cutting speed and VB - criterion of blunting. The whole procedure and its analytical expression is the subject of this paper.
