In CNC program, with the mathematical method of are spline function fitting tobulation curve

在CNC编程中用圆弧样条函数拟合列表曲线的数学方法，将双圆弧相切法应用于实际，使加工零件轮廓光滑连续，通过对大跨度型值点的加密，使逼近误差最小，减少尖角过渡，避免了爬行．

In CNC program, with dre mathematical methed of are Spline function fining tabulation Curve, the double-are tangncy is applied into practice to make the outline of the proceessed parts Smooth and Continuous; by tensifying thefor Span of Value dots, to make it appoach the minimun eror, for the closed angle transition, and avoid crawling.
