【Abstract】 Reverse engineering and rapid prototyping have been widely used as two separate advanced tech- niques.Little has been done for the integration of these two techniques.In order to enhance production’s performance and reduce the developmenttime,this paper proposed a novel procedure for the integration. The contour data are measured by laser scanning and are directly inputted to RP machine for manufactur- ing only through some simple processing.The method avoids the intermediate process of re- constructing surface model and generating STL files. Meanwhile,itdoes not need much skill in surface modeling and manufacturing.Main innovative algorithms thatdrastically contribute in reducing the productdevelopment time were also presented in detail.These methods will facilitate the use of reverse engineering geometric data for rapid prototyping.更多还原
