The effect of grit size and asperity blunting on abrasive wear

A model of abrasive wear, which has been used successfully to predict the forces and metal removal rates in abrasive machining is extended to allow the prediction of abrasive deterioration. Attritious wear of the abrasive and transfer of debris are both important factors in reducing abrasive wear over time, but small abrasives are more prone to becoming clogged by debris. Good quantitative predictions of experimental results are possible with the right input data, but much further work is needed to investigate the factors that are shown to control this process.
