项目摘要

A new laser conditioning method for micro wheel with ultra fine grit diamond, which are used for the micro grinding of micro grinding of micro-aspherical optics, is proposed. The new laser conditioning method has two stages. The first stage is the high-concentration truing process of micro-wheels. The second stage is the non-contact laser dressing. Generally speaking, the laser dressing is carried out with thermal process. Therefore, it is difficult to apply the laser dressing to diamond wheel. However, third harmonic YAG laser is used in proposed new laser dressing, and dressing is carried out with the ablation process without thermal process. In this research, laser conditioning device is developed and characterization of the laser conditioning is researched. Following results are obtained.1. Number of cutting edge on the micro wheel with ultra fine grit diamond is increased by the new laser conditioning method.2. When a power density of laser is high, the laser, which goes through the diamond, ablates the resin under the diamond abrasive grain. And the diamond abrasive grain fall.3. Titanium coating prevent diamond grains from falling down.4. Laser conditioning device is developed.5. Surface roughness of ground surface is improved by the laser conditioned diamond grinding wheel.

提出了一种针对具有超细粒度钻石的微型车轮的新激光调节方法，该方法用于微薄片光学元件的微观研磨。新的激光调节方法有两个阶段。第一阶段是微型轮的高浓度曲折过程。第二阶段是非接触式激光敷料。一般而言，激光敷料是通过热过程进行的。因此，很难将激光调味料应用于钻石轮。但是，第三个谐波YAG激光器用于拟议的新激光敷料，并且在没有热过程的情况下进行消融过程进行敷料。在这项研究中，开发了激光调节装置，并研究了激光调节的表征。获得以下结果。1。新的激光调节方法增加了带有超细粒度钻石的微型车轮上的尖端数量。2。当激光的功率密度高时，通过钻石的激光将树脂在钻石磨料颗粒下消融。和钻石磨碎的谷物下降3。钛涂层可防止钻石颗粒降低。4。开发了激光调节装置5。通过激光调节钻石砂轮改善了地面的表面粗糙度。
