移动热源修整树脂结合剂砂轮（第三报）Q开关YAG激光改善修整效果的研究本研究旨在建立一种新的树脂结合剂砂轮表面热源点扫描修整技术。在先前的报告中证实了CW YAG激光的敷料效果。为了进一步提高YAG激光的修整效果，本文选用调Q YAG激光器作为修整工具，通过对作用砂轮表面的观察和对修整砂轮磨削结果的分析，对调Q YAG激光修整树脂结合剂砂轮的修整机理和磨削特性进行了实验研究。并通过与连续激光修锐效果的对比，验证了调Q激光修锐的效果。主要结论如下：（1）调Q YAG激光束扫描树脂结合剂砂轮表面比连续激光束具有更好的修锐效果。(2)在所有调Q频率下，用2kHz调Q激光修锐树脂结合剂砂轮的磨削性能最好。(3)在较低的调Q频率下，由于激光束提供的热能变化剧烈、频繁，激光束照射后修整砂轮表面产生的热影响组织被完全去除。
Dressing of Resinoid Bond Wheel with Moving Heat Source (3rd Report) Improvement of Dressing Effect with Q-switched YAG Laser Toshikatsu NAKAJIMA, Kazuhito OHASHI and Daisuke YAGI The purpose of this study is to establish a new dressing technique of resinoid bond wheel by scanning the point of heat source on wheel surface. Dressing effect with CW YAG laser is testified in previous report. In this paper, Qswitched YAG laser is selected as a dressing tool for making more improvement of dressing effect with YAG laser, and dressing mechanism and grinding characteristics of dressed resinoid bond wheel with Q-switched YAG laser are experimentally discussed by observing the acting wheel surface and analyzing some grinding results with dressed wheel. Furthermore, dressing effect with Q-switched laser is verified by comparing with that with CWlaser. Main conclusions obtained in this paper are as follows : (1) Scanning Q-switched YAG laser beam on resinoid bond wheel surface results in better dressing effect than that with CW laser beam. (2) Dressing with Q-switchedlaser of 2kHz in Q-switch frequency brings out best grinding characteristics of resinoid bond wheel in those of all Q-switch frequency. (3) In lower Q-switch frequency, heat affected structure generated on dressed wheel surface is completely removed as soon as laser beam is irradiated because of radical and frequent variation of heat energy supplied with laser beam.
