Abstract: This paper gave an example of emulational system of the numerical control lathe. It introduced the design and implement of an important module-numerical control kernel. It expatiated the implement of three aspects which included input and display, code translation, intelligent checking error, and it also provided constructing bintree algorithm about language G’s syntax analysis. It realized the numerical control kernel emulation thoroughly using Lingo.
