| Abstract: | According to the method of error control in measuring dies and moulds with non-geometric three-dimensional shapes, this paper presents an algorithm for rational curve fitting with control accuracy by limiting the maximum distance from the curve segment to the chord between two knots and comparese it with Bezier cubic curves and parametric cubic Spline curves. |
