在对金刚石框架锯锯切加工动力学和锯切破碎机理模型的研究基础上,通过单颗粒金刚石划痕、单个金刚石结块切削石材的系列实验,测量并分析了金刚石框架锯锯切加工时的切削力特征及其影响因素。结果表明,单颗粒金刚石和单个金刚石结块以不同切削路径切削时的切削力不同的特征,反映了切削断裂过程性质的变化;金刚石浓度低和金刚石颗粒直径小时金刚石磨粒形状和切削方位对切削力有较大的影响。减小切削深度、使用切削液、在已切削表面上切削时,切削力下降。在框架锯锯切中,单颗粒金刚石承受载荷不高,考虑到磨粒切削干涉和重复切削的影响,单颗粒金刚石承载大约在5～15N之间。
Based on the study of sawing and cutting mechanism and sawing and breaking mechanism of diamond frame sawing, a series of experiments were carried out by using single-grain diamond scratch and single diamond cutting to cut stone. The results of diamond sawing Cutting force characteristics and influencing factors. The results show that the characteristics of cutting force when cutting single diamond and single diamond are different with different cutting paths, which reflect the change of the nature of the cutting and breaking process. When the diamond concentration is low and the diamond particle diameter is small, Force has a greater impact. Reduce the depth of cut, the use of cutting fluid, cutting the surface has been cut, the cutting force decreased. In the framework of sawing sawing, single-grain diamond bearing load is not high, taking into account the impact of abrasive cutting interference and repeated cutting, single-grain diamond bearing about 5 ~ 15N between.
