Influence of machining conditions on the energy consumption and productivity in finish hard turning

Abstract

In this paper such mechanical characteristics as cutting forces, cutting energy, specific cutting energy and volumetric machining rate were selected forfinish turning of hardened 41Cr4 alloy steel with variable cutting speed and feed rate using commercial CBN tools. In addition, a specific energetic characteristic of the hard machining process was performed, and the machine tool used was taken into account. This approach is focused on the prediction of the relation between the specific cutting energy and the volumetric machining removal rate and comparison of hard machining process with other machining processes in terms of their productivity.
