Study of different cutting strategies for sustainable machining of hardened steels

Abstract

This paper studies the power consumption of different cutting strategies in face milling operations in order to evaluate the efficiency of each cutting strategy. The experimental procedure evaluates the machine-tool efficiency by estimating cutting forces and measuring the power consumption. After modeling the efficiency of the machine-tool at different states (idle, fast movement and cutting at different conditions), the cutting strategies and cutting parameters are analyzed and compared in terms of sustainability (CO2 emissions) and quality (surface roughness). The optimal cutting strategy to ensure a predefined quality specification is also derived.
