摘要: An approach to laser dressing of alumina grinding wheels is proposed based on solidification microstructures associated with rapid cooling rates obtained in surface processing. Laser forms characterized by multifaceted grains that are expected facilitate the micro-scale material removal during precision machining. A detailed investigation variation grain size and melt depth fluence conducted. The results correlated calculated derived from a thermal model. In addition, microscopic observations, formation stacking individual formed suggested.
