Research And Implement Of NC Machining Lathe Auto Programming

With the Wide application of Computer in manufacturing, the NC machining Auto programming, which is an important component of Computer-Aided Design and Computer-Aided Manufacturing (CAD/CAM), has been the key technology to improve the productivity and create more economic benefits in modern manufacturing.From the view of supporting the project of Jiangsu scientific technology, the key algorithms and technologies are deeply investigated during developing a NC machining Auto programming system for NC lathing, which is introduced in this paper. Based on the study of IGES; STEP, especially the study of DXF, a program interface is developed, by which the data can be shared among different CAD systems. According to the different Characters, the respective tool paths are designed. And by a machine configure file, the General postposition process is deal with. On the research of the general simulation technology that is based on the NC codes. By analyzing the characteristics of the CNC system and the NC codes, a set of general simulation interface is developed.Last, under the direction of OO-SE, analyze and design the NC machining Auto programming system. The system has deeply improved the generating efficiency of NC code...
