摘要
采用领域为载体、模型为中心的方法开发计算机数控系统,使用UML/OCL在通用建模环境工具中对CNC系统进行元建模。针对数控领域进行特性分析,提出了一种面向CNC系统领域的CNCVFC元建模方法,采取多视角的方式捕获CNC领域的特征,依据特征描述CNC领域构件及其交互关系,并映射到相应的视图平面,以视图为容器建立相应的领域元模型。该方法融合了视图、特征、构件三维关系。阐述了CNC元建模的过程,包括结构元建模、功能元建模及非功能元建模三个方面。以一个车床CNC系统的模型应用为例验证了CNC元建模方法及建模过程的正确性,为CNC系统的个性化定制和快速开发提供了新的方法。
Methodology development of CNC system takes the field as a carrier centric model, which applies UML / OCL in GME for CNC system meta-modeling. For the fieM characteristic analysis for CNC, a CNC fieM oriented CNCVFC meta-modeling methodology was proposed, which combined the view, feature, component three-dimensional relationship. According to field characterization CNC members and interactions, multi-view approach captures features CNC field was adopted, which mapped to the appropriate view plane to establish the appropriate view of the container field meta-model, CNC elaborated meta-modeling process, including structural meta-modeling, function meta-modeling and non-functional meta-modeling of three areas. A lathe CNC system model was used as an example to verify the correctness of the meta-modeling methodology and modeling process for the CNC system customization and rapid development which provided a new methodology.
