摘　　要：基于框架锯锯切加工运动学分析、单颗粒和单结块切削力试验结果 ,讨论了采用计算机模拟框架锯锯切过程中所需的运动学、金刚石结块磨损和金刚石颗粒切削力模型 ,以及模拟过程图。采用简化方法计算了金刚石结块表面的理论金刚石颗粒数 ;结合对金刚石结块磨损的研究结果 ,用MontoCarlo方法生成了结块表面的金刚石颗粒的出刃高度、分布位置和磨损形态 ,生成了数字化的金刚石锯条 ,为计算机模拟框架锯锯切加工过程 ,提供了基础数据。In order to simulate the frame sawing process by computer, the number of diamond grits per unit area, the distribution of diamond grits per segment and the effective depth of cut of diamond grits were calculated by a new method. The Monte Carlo method was applied to generate the distribution,the protrusion height and wear pattern of diamond grits on the segment surface based on the results obtained in the previous studies of scratching tests with single point tools and single segments by frame sawing test in a model machine and a practical machine. Finally a digital blade can be calculated for the simulation of frame sawing process.
