Papers by Keyword: NC Code Interpreter

Abstract: Based on Microsoft GRETA regular expression, the engraving machine NC code interpreter is designed. It is constructed from lexical anlysis module, syntax and semantic analysis module and decoding NC code. In the anlysis modules, regular expression is used in matching NC code, as an analysis tool. Besides, the interpreter is compiled in VC++ 6.0 that is a Microsoft compiler about C++, in order to realize designed function more efficiently.The interpreter can realize the function of interpretation and information extraction. It has good reliability and high expansibility.

Abstract: After the virtual NC real-time machining process control technology is studied, we design the NC code interpreter using the pipeline control method of overlapped resources in this paper. In order to improve the availability of interpreter, the design adopts the function pointer array and expression evaluation algorithm. By using two methods, the scalability is enhanced. Also the versatility is improved by using keywords information table to some extent. The system achieves a straight line and arc of the trajectory interpolation by the digital sampling algorithm and makes the efficiency improved by using RCS communication mechanism, windows thread and timing mechanism.
