The relation between the traverse dressing of vitrified grinding wheels and their performance

A new model of the dressing of grinding wheels by diamond blade or single point tools is proposed. It is based on the statistics of brittle fracture of bonds and grits, and on the geometrical interaction between the grits and the dressing tool. It successfully predicts the measured topography of wheels dressed in various different ways, and in combination with a model of abrasive wear, can successfully predict the forces in surface grinding tests, and the resulting workpiece roughness. There is much scope for using the model in its present state as a means of assessing the likely effects of changing process parameters on the performance of a grinding process, but with better measurements of the input parameters it requires, its accuracy and effectiveness could be improved.
