Development of the wheel which aimed at the diffusion for image processing and the image processing system for wheel surface

以刃口分布为特征的砂轮表面形貌对磨削表面粗糙度、磨削力、磨削温度等有很大影响。因此，要优化高质量的磨削工艺，就必须对砂轮表面形貌进行精确测量。本研究通过对车轮表面大量显微图像的测量，研制了一种用于车轮表面形貌评价的新型测量系统。通过本研究得到的主要结论如下：1.采用磨粒与结合剂表面颜色浓度不同的砂轮进行刃口分析是有效的。只照射垂直于砂轮表面的光，并调整光量。有可能使切割刃从其他部分中脱颖而出，并且切割刃的提取变得如此容易。通过聚焦刀刃的磨损平坦区域，测量砂轮在任意角度下的刀刃与显微镜的距离。然后，用该距离作为最外轮面，即可显示轮子的形状。显微镜的距离是抓住刀刃的高度方向。然后，通过图像处理找出每个距离的焦点区域，从而测量出刀刃的高度。

The grinding wheel surface topography characterized by the distribution of cutting edges has strong influence on grinding results such as surface roughness, grinding force and temperature. Thus, to optimize high-quality grinding process, it is necessary to measure exactly the wheel surface topography. In this research, the new measuring system developed for the evaluation of the wheel surface topography by means of measuring the numerous microscopic images on the wheel. By this research, the main conclusions obtained are as follows :1. It is effective in the analysis of cutting edges when the wheel which has a difference in color concentration in the abrasive grains and the surface of bond is used.2. Only the light which is vertical to the grinding wheel surface is irradiated, and the amount of light is adjusted. It is possible that the cutting edges is made to stand out from other parts, and the extraction of the cutting edges has become easy as that effect.3. The distance of cutting edge in the optional angle of the wheel and the microscope is measured by focusing on the wear-flat area of the cutting edge. Then, The form of wheel can be shown by using that distance as the outermost wheel surface.4. The distance of microscope is the height direction of the cutting edge is grasped. Then, the height of cutting edge is measured by finding the focus area of each distance by the image processing.
