heal.abstract	This paper deals with localization of curved surfaces, meaning the optimum positioning of a target surface obtained by some manufacturing process with respect to an ideal design surface. The localization problem is formulated as an optimum parameter estimation problem involving rigid body translations and rotations obtained through unconstrained minimization of a distance norm. An iterative localization algorithm has been developed which terminates when the magnitudes of rigid body translations and rotations become smaller than preset threshold values. To reduce the cost of localization for large amounts of data arising in high precision applications involving free-form surfaces, methods to improve the efficiency of the process based on coherence considerations of the input data are investigated. An example based on actual measured data from a manufactured sculptured surface illustrates our technique.	en
