Abstract

In order to gain insight into the material removal mechanism of abrasive machining processes, single-grain cutting is a useful and widely adopted technique. In most of the works on this subject, the single abrasive grains are bonded to a substrate by soldering, electroplating or simple adhesive bonding. As a result, the grinding tool bond’s influence is largely neglected. This publication shows a new variant of single-grain cutting that makes it possible to quantify the influence of the bond on the material removal mechanism. Specimens with different bond hardness are prepared using a sintering-based additive printing process. In single-grain cutting experiments, the influence of the Rockwell hardness of different bond types on the material removal efficiency was investigated. Among other things, a reduction in the specific scratch energy by 40% and an increase in the grinding force ratio by 70% were found when using an iron-based bond with increased hardness, compared to a softer, steel-based bond. This is a result of an increased grain protrusion under load for the grains in the harder bonds which leads to an increased material removal efficiency.
