【摘要】 为了改造传统制造设备以实现快速柔性制造理念,设计了柔性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自动数控编程设计方法。通过分析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,进一步对图形数据作分类排序处理,然后自动生成加工的数控代码文件。系统为了对生成的NC代码进行校验,设计了具有加工动态仿真功能的模块,提高了加工效率和加工质量。更多还原

【Abstract】 Agility Manufacturing needs a rapid and flexible manufacturing cell.In order to rebuild traditional equipment to respond rapid and flexible manufacturing,a flexible mould system and its components for metal sheet punching and shearing was proposed.Technique of NC programmed in graphics processing system was particular explained.Based on analyzing the structure of DXF files,the data information requested for NC machining was gotten.According to punching technics conditions in the workshop,the data was classified and ordered again,and NC codes were automatically created.A plane dynamic model was given to simulate machining process and verify the NC code,which improves machining efficiency and quality.更多还原
