High Speed Measuring of a Grinding Tool Surface Topography by a Voronoi Diagram

摘要

It is very important that a grinding tool surface topography is measured and analyzed. In this paper, a line scan camera is installed in our three dimensional measurement system by shortening a measurement time. In this experiment, a diamond grinding wheel SD140Q100M is employed. As a result, the time can be reduced to about 24[s] from 1380[s]. On the other hand, a voronoi diagram is introduced as an evaluation method of a distribution of cutting edges on the grinding tool. According this method, the dispersion can be visualized. Furthermore, it is found that the voronoi region has a relation to a protrusion height of the cutting edge.
