【摘要】 提出了一个椭圆曲线节点划分的新方法,用于数控车削此类零件编程的数学预处理。该方法的实质是用阿基米德螺旋线去逼近离散椭圆。计算结果证明,用此方法可显著减小逼近误差和避免大量的数据处理和存储。更多还原

【Abstract】 A new method for node dividing of ellipse was presented,it can be used for mathematics preparing process of this kind of curves before programming.The principle of this method is to use Archimedes spiral to approaching ellipse.The calculating result shows that the approaching error is decreased remarkably,and the processing and storing of large sum data is avoided.更多还原
