| 摘 要： | 以相似理论为指导，从相似系统的角度对不同数控系统指令之间的相似性、相似元、相似度等进行多层次地分析和研究；根据相似元的划分原则，定义了各级相似元，量化了其特征值和属性值；给出了计算数控指令相似度的数学模型，并对数控指令的确定性相似和模糊性相似给出了确切定义，为不同数控系统之间数控指令的转换打下基础。

| Abstract: | Based on theory of similarity, analyze the similarity, similarity units and similarity degree at multi-levels from system of similarity standpoint between different NC systems. According to partitioning principles of similarity units, define the similarity units in all-levels and quantify their eigenvalues and attribute values. Give the mathematical model to compute the similarity degree of NC instructions. Define the deterministic similitude and fuzzy similitude of NC instructions, which provide the foundation for the translation of NC instructions between different NC systems. |
