Investigation of statistical and probabilistic characteristics of the working surface of a grinding wheel

The development of perfect design techniques for grinding operations is largely constrained by the lack of adequate conventional models of the working surface of a grinding wheel. In order to improve the parameters of the working surface, the statistical distribution of the distances between the tops of abrasive grains on the working surface of a grinding wheel was studied. When conducting a physical experiment, the working surface of the grinding wheel was rolled over an aluminum sample to get abrasive grain prints. The prints were photographed and the obtained images were processed by a computer. The analysis of the experimental results provided new information about statistical distribution characteristics of the parameters under study. The results of research will be useful for developing more adequate probabilistic models of the working surface of a grinding wheel, numerical procedures for calculating grinding process parameters, and computer-aided design systems for abrasive machining.
