  • Abrasive Size - an overview

    The concentrations as well as the size of the abrasives have an effect on MRR. There are three distinct regions of MRR dependence on abrasive concentration (Lee et al., 2009; Luo and Dornfeld, 2003) (Figure 11.11).First, MRR rapidly increases with an increase in abrasive concentration, which indicates that chemical removal of material is dominant at low concentrations.
