Abstract
In this paper, a simultaneous measurement of profile and surface topography of a grinding wheel by image procession is proposed. The rough of abrasive and the successive cutting edge spacing of super abrasive electro-deposition cylindrical wheel are measured as the surface topography. The shade images of the rotating wheel are projected to monochrome CCD camera by parallel optical lighting. The image that composes of the maximum value of the light and shade value of the pixel is defined as the Maximum image. The image that composes of the minimum value of the density value is defined as a minimum image. The outline of the minimum image corresponds to the wheel profile. The outline of the maximum image corresponds to the wheel base. The maximum image is subtracted from a minimum image, and the width of a remaining image is an amount of the abrasive asperity. The edge position of the image changes along with the wheel rotation angle. The successive cutting edge spacing is derived from this change. The effectiveness of the measurement methods were verified by the experiment and the numerical simulation.
