Research on Reverse Engineering’s Parameter System

This paper analyses the current situation of reverse engineering. It points out that the reverse engineering used in manufacture industry obtains measuring data from the objective prototypes, adopts appropriate data processing methods according to obtaining data methods and types and accomplishes the 3D reconstruction and reappearance of the objective prototype. Because of kinds of facts, such as, manufacturing errors, measuring errors, and so on, there is obvious gap between manufacturing data and prototype parameters, so manufacturing data may be useless in some cases. In view of exiting situation, the paper puts forward that there is a parameter system that includes the objective prototype parameters, reconstruction parameters and original design parameters in the reverse engineering. The paper elaborates that the certain parameters must be obtained according to the given demand in a given situation and considers that the reverse engineering used in manufacture industry should evaluate reversely the original design parameters that are foundation of making objective prototype and new products. On this basis, this paper divides the project implementation of reverse engineering into I, II stages and gives the corresponding working process. The working process underlines the “innovation” function of reverse engineering, widens the application range of reverse engineering.
