Abstract:A new and efficient algorithm for match of fre e-form surface is presented. It is based on the Minimum principle for eliminati ng the location error of surface measuring. By means of rotation and movement of free-form surface, the pre-location is realized. According to an improved alg orithm of coordinate alternation, the adjustment is accomplished. So it can deal with the problem of surface match better than before. It provide a good way to measure the profile of free-form surface. The example shows that the algorithm is correct and efficient.
Keywords:Free-form surface  Measuring  Best match
