3D Noise Generation and Removal of Measured Grinding Wheel Topography Using a White Light Interferometer
In order to precisely measure grain protrusion topography of diamond grinding wheel, the measured noises should be removal, but it has not been clear how these noises are produced. Hence, a white light interferometer was employed to measure the SD60 grinding wheel surface. The objective is to evaluate the grain protrusion parameters. It is shown that the noise generation is related to the orientation of measured point. The noise occurs as its vector angle is less than 45°. Moreover, the grain protrusion topography may be displayed though noise removal, noise-data restructure and grain contour protection. The grain protrusion height, bond-tail height, rake angle and clearance angle are averagely 108.2 μm, 49.1 μm, -68.6º and 26.4º, respectively.
