| 摘 要： | 现有的基于微机开发的数控加工系统都是人工调试完成后加载运行,为了能够依据AUTOCAD绘图系统提供的信息自动生成数控加工代码,本文对基于PMAC卡的数控加工代码生成及动态在线监测系统研制过程中遇到的问题进行了研究,重点研究了如何利用DXF文件中的参数进行曲线拟合,详细介绍了NURBS曲线算法的实现,为后续的工作打下了基础。

| Abstract: | For the existing open NC system based on PC,numerical control codes are loaded into numerical control machine tool after debugged manually outside.In order to generate numerical control codes automatically from AutoCAD,the existed problems for developing an open CNC based on PMAC were discussed,the method of curve fitting using parameters readed from DXF was studied,and the realization of NURBS curve algorithm was introduced. |
