【摘要】 根据ＣＮＣ系统图表显示功能的特点，研究一种采用Ｃ语言在高性能ＣＮＣ系统上实现交互式图形菜单功能的方法。按图形拓朴法，采用链表数据结构描述所要显示的图形，并建立图形管理函数库。具有执行速度快、内存消耗小、操作处理简便等优点，在自行开发的激光加工ＣＮＣ系统上运行稳定、可靠。更多还原

【Abstract】 In accordance with the features of graphic display function of a CNC system,a methodfor realizing the interactive graphic menu in a high performance CNC system with C-languageis discussed.By the graphic topology theory,a chained list data structure for describing thepicture to be displayed is used and a graphics management function library is developed.Thismethod has been applied to a self-developed laser processing system stably and reliably.更多还原
