摘　　要：传统的规则提取算法只是对单一的条件属性特征推理单一的决策属性值进行规则提取,为实现刀具智能选择,本文提出了一种通过加工特征和工件尺寸对刀具进行选择的规则提取算法,采用粗糙集进行刀具型号的规则提取,对刀具尺寸的选择采用区间值的基本理论,最后通过一个实例验证该算法的有效性。In order to achieve intelligent tool selection, a rule extraction algorithm based on machining features and workpiece size has been put forward in the text. The rough sets have been applied to gain rule extraction of tool model. The basic theory of interval-valued has been adopted to select the size of tool. Finally, the effectiveness of the algorithm has been validated by an example.
