The paper briefly introduces both the internal and external developing modes of the reverse engineering software Surfacer.By applying its re-development function and together with blade inspection technology,a turbine blade forging inspection system has been researched and developed.How to write the program was also introduced by using example program.After application test,it indicated that the system can complete the inspection operation successfully.The interface is simple and clear,easy to operate.By comparing with the traditional inspection method,it is featured with high speed and high accuracy.The application of the inspection system will bring a big boost for development of reverse engineering software in actual production.
