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的。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,对基于PMAC卡的数控加工代码生成以及动态在线监测系统研制过程中遇到的问题进行了研究。重点说明了如何利用DXF文件中的参数进行椭圆(弧)曲线拟合,详细介绍了椭圆(弧)曲线拟合算法的实现。比较结果进一步验证了该算法的正确性和有效性,为后续的工作奠定了基础。
The existing microprocessor-based NC systems are loaded for operation after manually debugging.In order to automatically generate numerical control codes in accordance with the information from AutoCAD system,the NC codes generation based on PMAC and the issues of development of dynamic on-line monitoring are researched.The ellipse（arc） curves fitting by adopting parameters in DXF file are emphasized,and the implementation of ellipse（arc） curve fitting algorithm is introduced in detail.The result of the method is compared with original graphic,and the correctness and effectiveness of the algorithm are verified,this lays a foundation for follow-up works.
