Data process for reverse engineering technology
Reverse engineering has become an important tool for CAD model construction from the data points,measured by a coordinate measuring machine (CMM),of an existing part.However,due to special structure and complex topology relation,obtaining full surface data of a prototype is not an easy thing and should carry out complex data process procedure to get global model.The paper presents a method for pre-processing data points for curve fitting in reverse engineering.The proposed method has been developed to process the measured data points before fitting into a B-spline form.The method is implemented and used for a practical application in reverse engineering.The result of the reconstruction proves the viability of the proposed method for integration with current commercial CAD systems.
