✦ Synopsis

The preparation of the use of resin-bonded superabrasive grinding wheels remains a problem despite their availabilities on the market in the past years and possible technological advantages. In this paper, an acousto-optic Q-switched Nd:YAG pulsed laser is applied to dressing resin-bonded superabrasive wheels in orthogonal direction. The author proposes a systematical study on the mechanism of selective removal, crater ablated by single pulse and surface topography after dressing, and consequently presents a feasible method of selecting irradiation parameters and summarizes the dressing features and disciplines of dressing e ects in uenced by these parameters. Experiments results indicate the surface topography dressed by acousto-optic Q-switched YAG pulsed laser dressing is much superior to mechanical dressing and CW laser dressing.
