Abstract: Semi-fixed abrasive tool is a new developed grinding wheel which can adjust abrasive grain near the workpiece-abrasive interface according to the situation of the hard and large grits, damaged surface layer generated by the scratch or crack could be decreased when using semi-fixed wheel. Porosity, one of the most important parameters to evaluate trap effect, was studied based on the analysis of uniform scratch and it’s effect on the polishing time, contact models between circle abrasive grain, line boundary an…
