Vplyv geometrie reznej hrany na tvorbu triesky a zložky reznej sily

Abstract

This paper deals with influence of cutting edge geometry on chip formation and components of cutting force components. The insert with the flat surface is compared with the insert containing positive geometry in order to produce acceptable chip form. It was found that cutting forces components are lower for the insert having positive geometry together with the lower energy consumed for chip formation. Furthermore, the acceptable chips in the form of short sequence is developed as contrasted against the insert of flat surface producing long chips. The measured cutting force components are decomposed in order to distinguishes between the components associated with chip formation and energy consumed in the produce new surface. Chip ratio for the flat insert is more and the shearing angle is therefore less.
