摘要:

采用钎焊金刚石砂轮对两种硬质合金进行磨削实验,通过测量磨削过程中的磨削水平力和垂直力,对砂轮所受的单位宽度法向力、切向力和力比进行了研究。建立了单颗磨粒磨削力与加工参数间的理论模型,并用实验数据进行验证。理论分析了磨削深度、进给速度对单位宽度磨削力、单颗磨粒磨削力及力比的影响程度。

Abstract:

Grinding forces were measured in the grinding of two typical cemented carbides with a vacuum brazing diamond wheel. The specific normal force, tangential force and the grinding force ratio acted on the grinding wheel were investigated based on the measurement data. The theoretical models of the forces per grain with the grinding process parameters were established, which were verified by experimental data. The different influences of depth of grinding, feed rate and circular velocity of the grinding wheel on the specific grinding forces, the forces per grain and grinding force ratio were explained theoretically.

Key words: vacuum brazing diamond wheel, cemented carbide, grinding force, grinding force ratio
