This aaticle introduces the former milling processes and an improved precision blanking processes of Wingshaped Prop,one of the electrical switch parts. The layout of sheet metal material and the struture of mold are elaborated. After roughcast blanking in lathe machine, the practical fixtures and processes in lathe processing are mainly introduced in this paper.The economic benefits contrast between the old and new processes is analysed.This article also discusses and finally demonstrates the reasonableness and advantage of the new precision blanking process.
