本文以磨粒磨削性能为基础,根据对不同修磨角度的磨削几何学分析,提出评价钢坯修磨砂轮磨削能力指标——磨除能力系数C_(ge),C_(ge)=Zw/F_nV_s。该指标物理意义明确,经试验证明与金属切除率、砂轮磨损率、比磨削能耗、磨削力比等密切相关,故可做为修磨理论研究的一个基础参数使用。文中还给出了上述诸关系的若干回归结果。 In this paper, based on the abrasive grinding performance, according to the grinding geometry analysis of different grinding angles, it is proposed to evaluate the grindability index of grindstone grinding wheel, grinding gearing coefficient C ge, C ge Zw / F_nV_s. The index has a clear physical meaning and has been proved to be closely related to the metal removal rate, the wear rate of the grinding wheel, the energy consumption of grinding, the grinding force ratio and so on. Therefore, it can be used as a basic parameter for grinding theory research. The article also gives a number of regression results of the above relations.
