In this paper, an adaptive adjustment method of coordinate system in the evaluation of profile error of adaptive free curve is proposed. The method uses the corresponding feature point method and DFP --- one-dimensional search method to achieve adaptive adjustment between the measured curve and the theoretical curve. Therefore, the influence of position error on the evaluation of profile error is separated and eliminated, and the accuracy of curve profile error is ensured.
