Effects of abrasive grit shape on grinding performance

The quality of grit in grinding wheel has predominate influence on the grinding wheel performance, such as wheel sharpness and wheel wear. This paper presents an investigation on the effect of difference grit shapes on grinding force and grit holding capacity. Some critical grinding behaviours are analysed in relation to grit shapes to establish a foundation for grit quality assessment. A desirable grit shape is identified for better cutting efficiency and grinding wheel life.
