Based on the on-machine measurements feature sampling results, put forward a new way to get free-form surface processing errors, and the method of evaluation surface profile error, this method based on the feature sampling to get coordinate data, a few measuring points on the processing surface, Use the least square method to optimize the distance between the reconstructed surface and the original theoretical surface; To obtain the free-form surface machining error, and model surface profile error of experimental process to analyze. The experimental results show that, Surface reconstruction process surfaces method based on feature sampling can machine, effective obtain the free-form surface machining errors.
