Three - dimensional measurement of wheel surface topography with image processing

4^thReport : High-speed image acquisition by the line camera and analysis of cutting edge distribution using a Voronoi diagram

Abstract

Measurement and analysis of grinding wheel surface topography is important because it has a large influence on grinding accuracy. Therefore, a measurement system that can numerically express all cutting edges by image processing has been proposed. Using to this system, it is possible to evaluate the circularity, area of wear-flat, and the presence of external and internal damage. This study aimed to reduce the measurement time by installing a line scan camera. Furthermore, a Voronoi diagram is introduce to obtain new criteria for the distribution of cutting edges and protrusion height. In comparison with the conventional measurement system, measurements and analyses could be performed in a shorter time using this newly developed system. The Voronoi diagram could be applied for these evaluations.
