摘　　要：超硬磨料砂轮的修整是制约其优良磨削性能发挥的瓶颈 .本文采用声光调QYAG脉冲激光径向辐照砂轮表面 ,利用自己开发的一套在线检测闭环控制系统 ,控制激光脉冲的输出 ,对砂轮表面进行修整 ,达到了理想的整形精度 ,并发现可同时实现修锐 ,使超硬磨料砂轮的激光修锐和整形可合二为一 .通过单脉冲试验研究总结出激光参数和工艺参数对砂轮修整效果的影响特点 .选择优化的参数进行修整 ,获得了较好的修整效果 .The difficulty of truing and dressing of superabrasive grinding wheels is the key problem to restrain their application. Turing and dressing of superabrasive grinding wheels by acoustic-optic Q-switched YAG pulsed laser in wheels radial orientation are studied. An accurate machining system to measure and scour online is designed, the pulsed laser is controlled to ablate the wheels, the high truing precision is achieved. Truing and dressing can be carried out at the same time. The influence of the technology parameters has been summarized in the single pulsed laser ablated experimentation. Optimized parameters are chosen in the experimentation and ideal result is obtained.
