Abstract
Single-pulse and continuous-pulse ablation was carried on bronze-bonded diamond grinding wheels with 300W xenon lamp pumped YAG pulsed laser and 80W acoustic-optic Q-switched YAG pulsed laser respectively, in order to choose appropriate laser equipment and parameters for improving the efficiency and accuracy of grinding wheel turing and dressing. The morphology of the wheel surface after laser irradiation was analyzed by means of stereo microscope. Through theoretical derivation, a formula was obtained to reduce the option range of laser and parameters effectively under the premise of guaranteeing the accuracy and efficiency. It helps choose appropriate laser parameters for turing and dressing different grinding wheels more effectively. Compared with xenon lamp pumped YAG pulsed laser, acoustic-optic Q-switched YAG pulsed laser has lower single pulse energy, higher pulse frequency, narrower pulse width, higher peak power, so it is more suitable for high accuracy and efficiency turing and dressing of grinding wheels.
