Novel structure of NC program processor for CNC system

  • A novel structure of the interpreter for the special vendors using different standards was presented. A new structure was proposed for the purpose of reducing the time while developing a new interpreter for computer numerical control (CNC) system. The interpreter was divided into three sub-modules called input data, internal data interface and functions. Numerical control codes were formally expressed in internal data interface so as to separate the other two sub-modules. The computation in the interpreter could be independent of the input data format because of this internal interface. Relationship between the numerical control codes and features was studied. Numerical control codes were sorted based feature. And gathering concept was introduced in functions sub-module to export data by means of this classification. This method facilitates functions independence. The results show that sub-modules could be reused with this structure. The development efficiency of the interpreter could be rapidly improved for different NC program formats.
