ANALYSIS OF THE EVOLUTION OF THE DURABILITY OF CUTTING TOOLS DEPENDING OF FUNCTIONAL GEOMETRY

Abstract

The paper aims to analyze how the durability of the cutting tool evolves as a result of the variation of the functional geometry of the tool at the transverse feed. The technological process of turning with transverse feed is realized with variable cutting speed, and this also causes a variation of the functional geomtry of the tool. Thus, in the paper was established the optimal construction geometry of a lathe that can be used for turning a piece of a certain diameter. Under these conditions, a correlation between the values of the functional geometric parameters of the knife used for transverse turning and the durability of the cutting tool was identified.
