It includes plastic forming simulation, mold CAD /CAE/CAPP/CAM, computer integrated manufacturing (CIMS) and reverse engineering. He has successively completed scientific research projects such as fine blanking die CAD/CAM, blanking die CAD/CAM, color TV part die CAD/CAM, panel die CAD/CAPP/CAM, CIMS application demonstration project, etc. Its research results have promoted the technical progress of the mold industry and achieved remarkable benefits in practical application. He has won many scientific and technological progress awards from the Ministry of Machinery Industry, the Ministry of Electronics Industry and the Ministry of Education, including the first prize 1, four second prizes and the third prize 1. As the chief designer, he completed the national 863 plan project-CIMS application project of Dongfeng Motor Company, and established the CAD/CAPP/CAM integrated system of automobile body and panel mold, which shortened the design and manufacturing cycle of automobile body and integral mold by more than one year. His research achievements won the first prize of GM China Scientific and Technological Achievements and the leading prize of SME University in 1998 and 1999 respectively. He has published 7 books, including CAD of Mould, CAD/CAM of Mould and Computer Application in Near Net Forming Operation, and published more than 20 papers/kloc-0. At present, doctoral students 17 and master students1person have been trained.
