Abstract: In the application of Reverse Engineering (RE) of part holes floating position error detection,an algorithm of Holes Position Tolerance border Template (HPTT) reasonable registration with the measured holes was presented.Based on the plane-floating characteristics of position tolerance,the measured holes and HPTT were projected to the baseline plane to build the influence regions,regional centers of measured holes and the projection points of hole centerlines in HPTT.The definitions of distance measure of template hole projection centers to the influence region centers of measured holes and the distance weighting factor were established.By a weighted Levenberg-Mar (L-M) quardt -iterative process of corresponding points in the baseline plane,the reasonable registration of HPTT and measured holes was achieved.An example was conducted to verify the feasibility and availability of the proposed algorithm.

Key words: reverse engineering, float position error, holes position tolerance border template, reasonable registration
