Least square and minimum circumscribed (maximum inscribed) parabollc three methods were used to evaluate parabollc profile error. MATLAB math functions were used to calculate the normal distance between points and plane free curve.Then rapid and accurate error evaluation of parabollc profile without datum was completed.The error was shown with diagrammatic view.The testing results show that the algorithm is correct.
