| 摘 要： | 分析了常见的砂轮表面形貌检测方法的局限性，阐述了激光三角法的基本原理．在此基础上，提出了激光三角法检测砂轮表面三维形貌的方法和装置，利用它可以对砂轮表面进行扫描测量，得到表面各点的三维坐标，随后通过origin软件的绘图功能和数据分析功能得到砂轮表面的三维形貌图和单个砂粒的三维尺寸．在实验中，得到了在航空发动机叶片磨抛中使用的60#杯形CBN砂轮表面0．5him×1．6mm面积的三维形貌图，某单个磨粒宽度为209．1μm，磨粒切刃突出高度为17．3μm．该结果与用美国WYKO的白光干涉三维表面形貌仪测量结果之间的误差为1．00％左右，这说明所采用的激光三角法测量砂轮表面三维形貌是可行的．

| Abstract: | The limitation of the normal measuring methods about the surface topography of the grinding wheel was discussed,and the theory of the laser triangulation was expounded.Then,a method of measuring the surface topography of the wheel using the laser triangulation was proposed and the measuring system was built.It was used to obtain the 3D coordinate data of the point on the wheel surface by scanning way.Then the 3D topography of the grinding wheel surface could be established and the 3D size of one single grai... |
