| Abstract: | An automatic programming system for a CNC lathe based on feature recognition is developed.First,the functions of the CNC lathe programming system are analyzed and a feature abstraction method for 2-D engineering drawing of AutoCAD is proposed based on feauture recognition technology.Then,the automatic programming system is designed and developed.Finally,an experiment is designed to verify the system.The automatic programming system adopts Unified Modeling Language(UML).The use case diagram and the class diagram are illustrated.The key technologies,such as feature recogniton technology,database technology for dimensional tolerance,and the tool-paths generation technology,are studied.All functions of the system are realized by programming with VC++and ObjectARX. |
