Research on the Quantitative Method of Brazed Diamond Tool Wears Characterization

A quantitative method which is named as ‘Wear Area Method’ (WAM) is proposed to characterize the brazed diamond tool wear in this paper. To different diamond grain forms, we present different definitions of their wear area. And with above foundation, the concept ‘Tool Wear Rate’ (TWR) is defined to describe the wear level of tool. Then we propose a corresponding measurement way which depends on the SEM photos and software Image pro plus to get the wear area. Finally, we set a face grinding experiment of sapphire to confirm the availability of this new method.
