Technique of graphics processing in agility mould for punching and shearing system design

Abstract

介绍了敏捷冲裁模具系统的组成模块及其功能结构．详细阐述了其中图形处理模块的数控编程技术的开发方法,通过分析数据交换文件(DXF)图形文件结构,提取数控加工所需的数据信息,再根据现场加工工艺要求,对这些图形数据作进一步处理,然后自动生成机床加工的数控代码格式．同时,该系统模块具有加工动态仿真和NC代码检验功能,从而提高了加工效率和加工质量．In order to respond to rapid manufacturing, an agility mould system and its components for metal sheet punching and shearing was proposed. Technique of NC programmed in graphics processing system was particular explained. On the basis of analyzing the structure of data exchange files, the data information requested for numerical control(NC) machining was gotten. According to punching technics conditions in the workshop, the data were processed again, and automatically create NC codes. A plane dynamic model was given to simulate machining process and verify the NC code, which improves greatly machining efficiency and quality
