摘要
从计算几何、函数逼近论等数学理论出发,给出了在绝对坐标系下同向双圆弧拟合的计算公式和算法,对平面参数曲线进行了同向双圆弧拟合,并在数控加工中得到了良好的应用。
Based on mathematical theories of calculation geometric and function approaching method, the biarc-curve fitting in the same direction was given in the original coordinates for arbitrary plane parametric curves and its calculation formula and arithmetic were given, which was applied in numerical control processing successfully.
