摘　　要：利用射线交面法获取模型中同经度面,根据面的类型、法向量、面积、中心坐标值等判断出同经度面中的阵列面,计算出Y方向上的阵列数量和距离;再利用类似方法获取同纬度面,计算出X方向上的阵列数量和距离,完成阵列特征的识别。试验结果表明:该阵列特征识别算法对于一般形状的工装零件普遍适用,准确率高达90%以上,对于复杂形状的工装零件准确率也超过85%,提高了工装数控编程系统的自动化程度,大大提高了数控编程效率。Using the ray cutting faces method to obtain the same longitude faces in a model, judging the array faces from the same longitude faces based on the face type, the nor- real vector, area, center coordinates and so on, and then the array number and distance in Y direction were calculated. Using the same method in X direction to calculate the array number and distance in X direction, and the identification of array feature was completed. The experimental results showed that the accuracy of identification algorithm for simple shapes was as high as 90%, slightly lower for complex shapes but also improved programming efficiency by 85%.
