阐述脉冲激光修整技术的基本原理和特点，从超硬磨料砂轮激光修整技术的工艺参数优化、数值模拟仿真两方面对其研究进展进行综述，指出该技术目前正面临的主要问题，并对其发展方向进行预测和展望。超硬磨料砂轮激光修整技术目前已经取得了较大的进步，但基础科学理论、砂轮表面质量评价、在线精密修整技术等关键性技术仍然是该领域非常棘手的难题，有待对其进行更深层次的探索和研究。

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.
