Status and prospect of laser truing and dressing technique for superabrasive grinding wheels

The fundamentals and characteristics of pulsed laser truing and dressing technique were illustrated, and the related research process was reviewed and commented from such aspects as optimization of technical parameters and numerical simulation of laser truing and dressing technique for superabrasive grinding wheels. The major problems in the laser truing and dressing technique were pointed out and the development trend was predicted and prospected. Although progress was made and lots of experiences were accumulated in terms of laser truing and dressing technique for superabrasive grinding wheels so far, crucial subjects such as the fundamental science theory, the evaluation system of grinding wheels surface and the precise in-process truing and dressing technique are still very troublesome in this field. Consequently, it requires further exploration and research in the future.
