Green key performance indicator based on embedded lifecycle energy for selection of cutting tools

Abstract

Many companies face increasing demands from markets to have environmentally friendly manufacturing processes. This paper proposes a Green Key Performance Indicator for selection of cutting tools, based on embedded lifecycle energy of the insert. This facilitates decision making to achieve green machining. Two insert materials were investigated; one solid carbide and one ceramic insert. The main work piece material was gray cast iron. The results show that the embedded lifecycle energy of a ceramic insert is considerably higher than for cemented carbide but, due to higher material removal capacity, the ceramic insert has a better Green Performance Indicator.
