Abstract

This paper presents a study of surface fitting techniques to provide a practical method to balance the fitting accuracy and surface smoothness in surface fitting process. The method makes use of the surface intrinsic feature as fitting criteria to minimize the influence of surface roughness such as tool marks to the smoothness of the reconstructed surfaces. The method has been experimentally verified through a series of preliminary measurement experiments. The results show that the developed method can reconstruct ultra-precision freeform surfaces based on measured discrete points, which is not only accuracy enough to characterize the form accuracy of measured objects but also smooth enough to avoid unwanted over fitting error.
