基于应力集中理论的磨削力模型
Model of Grinding Force Based on Stress Concentration Theory
摘要
Abstract
Stress concentration theory was introduced into study of grinding, and the stress concentration phenomenon in grinding process was analyzed. A single-grit model of grinding force was established based on stress concentration theory. The influence mechanism of grit-wear-area rate on cutting force was clarified with the model. Functions between grinding force and grit-wear-area rate was established. The functions showed the quadratic function relationship between grinding force and grit-wear-area rate, and the increase of the cumulative residual-grinding-thickness results in the rapid increase of normal grinding force. Furthermore, by taking the feature of the grinding wheel in use into consideration, functions of grinding force for multi-grit grinding wheel was established. The validity of the model was verified by the experimental data.关键词
