【Abstract】 Aimed to the limitation of present NC code compiler, e.g. specialization and difficultr to maintain, a method of developing general NC code compiler by using special compiling tools is presented. Introducing the compiling technology of programming language into NC code compiling, applying special compiling tools--LEX&YACC in compiler design, including code conversion to expand the traditional technology of NC code compiling and presenting the method of system customization, a new model of NC code compiling is built theoretically. Compare to the traditional NC code compiler, the compiler based on this model is more efficient in compiling process. Tree structure data management hierarchy and object-oriented general compiler design method is presented, they can not only maintain system customization but also ensure the stability and reliability of the system.更多还原
