Construction method of numerical-control code compiler

Abstract

The invention discloses a construction method of a numerical-control code compiler. The construction method comprises the following steps that an intermediate language format of a numerical-control instruction is defined; a lexical rule and a grammatical rule corresponding to the numerical-control instruction are formulated according to the G code format and the M code format; a framework program of the numerical-control code compiler is compiled, G codes and M codes are compiled, an intermediate language is generated, and the intermediate language is saved in a target file. According to the construction method of the numerical-control code compiler, the intermediate language and an ANTLR language recognition tool are adopted, the numerical-control code can be used repeatedly after being compiled at a time, and the computational effort consumed when a program runs is reduced; compiling is finished before actual execution of the program, errors in the code can be found in advance, and part reimbursement caused by the situation that the errors are found during execution of the program is avoided; the lexical rule file and the grammatical rule file are defined, a grammatical analysis algorithm and a lexical analysis algorithm can be automatically generated, and compiling by a developer is not needed; recompilation can be conducted for different code rules as long as rule files are modified.

Description

technical field [0001] The invention relates to a code compiling method, in particular to a compiler construction method. Background technique [0002] At present, CNC machine tools complete the processing of parts by executing CNC codes, and users use G codes and M codes to control the movement of the machine tool and perform auxiliary operations. The NC kernel program cannot directly read the NC code to process the parts. The part processing program must be preprocessed and decoded into corresponding processing instructions by the preprocessing program module, so that the NC system can process the parts. This part is usually called NC code compiler. As one of the core modules of the CNC system, the CNC code compiler needs to process a large amount of data, and its operating efficiency directly affects the stability of the entire system. [0003] There are two commonly used data preprocessing methods: interpretation method and compilation method. The interpretation metho...

However, this processing method requires a large memory

[0004] In the existing CNC system, the processing program needs to be recompiled every time it is executed, which increases the computational workload of the CNC system when it is running; when the code program is large, it requires a large memory, which affects the overall performance of the CNC system; it will only be found when the program is executed. Errors in the code, for large-scale CNC programs such as mold processing programs and engraving programs, the error will be found during the execution process, which will result in part reimbursement; the CNC code rules used by different CNC systems are not exactly the same, and need to be written repeatedly in different CNC systems syntax analysis algorithm, lexical analysis algorithm
