  • 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 grain can be obtained through analyzing those measuring data with the Origin 8.0. In the experiment, the 3D topography of 0.5 mm×1.6 mm area on the wheel surface were obtained. It also indicates that the width of a wheel grain was 209.1 μm and the height was 17.3 μm.The error ratio of this measuring was about 1.00%,compared with the measuring result using white-light interfering profilometer by WYKO from the US. It is concluded that the proposed method and system is feasible and satisfied.
