Abstract:This paper is concerned with a number of engineering applications of 2-D CNC laser cut-ting.The input method and CAD of parts drawing for the metal sheet are studied and the in-put and processing methods and laser processing of Chinese characters and artistic graphicalcharacters are discussed.The 2-D automatic optimal nesting and the algorithm are studied.The technological features of 2-D laser cutting and the processing as well as the technologyof auto programming and cutting simulation on screen are investigated.A data model for 2-DCNC laser processing is developed and the internal dynamic data structure of the softwaresystem is abstracted. An applied CAD/CAM system for 2-D CNC laser processing has beenworked out.The structure and functions and examples of operation are described.Some con-clusions are obtained.
Keywords:D CNC laser cutting  optimal nesting  auto programming  CAD/CAM
