Grinding Mechanism is very complex and difficult, and it can be simplified to a single abrasive grain grinding research. With the analysis of process and result of single abrasive grain grinding from experiment, the purpose can be achieved of understanding the complexity of the grinding mechanism. According to the characteristics of grinding process, the current domestic and international research status of single abrasive grain grinding experiments is introduced. The different experimental methods used by scholars are analyzed in detail, as well as grinding characteristics of single abrasive grain and chip formation mechanism of different characteristics materials. Finally, the current research difficulties of theory and experiment research are analyzed for the single abrasive grain grinding, and the further research direction is made.
