The generating mechanism of cutting edges in diamond dressing was studied in a simulated dressing test. The test involves a dressing process for a single abrasive grit mounted on the periphery of an aluminium disk.. Axial profile of this dressed surface was obtained by grinding a workpiece with the grit and subsequently tracing across the groove with a stylus instrument. The dressed surface of abrasive grit was also observed using a scanning electron microscope. The main results obtained are summarized as follows : (1) Any abrasive grits tested are not machined completely along the locus of the dressing diamond; but a line of retreat for the top of dressed grit is roughly consistent with the locus. (2) Dressed surface consists of asperities generated by micro-fracture and/or plateaux by their rubbing against the dragging part of dressing diamond. (3) Zirconia-alumina grit trends to have a plateau with flat and smooth surface. (4) The dressed surface for aluminium oxide grit is composed of large rugged asperities. (5) Wheel hardness infiuences the size distribution of the dressing particles.
