本文包括杯形砂轮的磨粒切削模型、计算机模型，以及工艺参数的优化研究等内容。运用上述模型，通过输入某些具体的工艺参数，可以获得磨削表面磨粒的切痕长度值Ｑｕ、变异系数Ｚｖ和磨削表面的切痕分布情况值ＳＳ［ｉ］，（ｉ＝１，２，３，…，ｍ），以及用线图方式表示的各工艺参数对磨削效果的影响情况，它为在具体的生产条件下选择合理的工艺参数提供了实用手段。 This paper includes the abrasive grinding model of cup wheel, computer model, and optimization of process parameters. Using the above model, the notch length value Qu, the variation coefficient Zv and the notch distribution value SS [i] (i = 1, 2) of the grinding surface can be obtained by inputting some specific process parameters. 2, 3, ..., m), as well as the effect of each process parameter on the grinding effect in the form of a line diagram, which provides a practical means for selecting reasonable process parameters under specific production conditions.
