A Mathematical Model of Single Grain Forces in Grinding Process

For the purpose of obtaining mathematical force model in grinding process, the contacting grain numbers and the single grain forces should be taken into considered. In this paper, a mathematical model was established for single grain forces calculation. A Matlab program is edited and the calculation results were obtained and discussed. In the work of this paper, only plowing and cutting forces were take into considered because that the sliding forces were proved to be neglected based on Hertz contact theory. Because of different micro-interacting mechanisms of plowing and cutting grains with workpiece material, different force models were developed separately.
