数控转塔式冲床NC自动编程研究

Study of NC Automatic Programming for Numerical Control Turret Punch Press Machine

摘要: 提出了一种基于特征的动态滑动匹配算法,用于从零件CAD产生的图形交换文件中识别基孔类型、提取基孔的形位参数。在此基础上,结合冲压工艺研制开发了数控转塔式冲床NC自动编程系统,可由零件CAD产生的DXF格式或IGES格式的图形交换文件自动生成零件的NC加工程序。

Abstract: A feature based dynamic slide match method for recognizing hole's type extracting hole's shape and location parameters from CAD exchange files is propsed.Software System for automatic make NC Program of numercal Control turret Punch Press machine is develeped based on the method.The Software system can generate NC program from CAD exchange files of DXF format or IGES format automatically on Computer.
