Abstract：

Based on the basic technology problems of the close clearance,difficult mold manufacturing and high requirement for the blanking equipment in the sheet blanking process,the major technology methods of the blanking were introduced.The currently common used methods were made into four categories: the polyurethane blanking,the roll blanking,the tensile stress blanking and the close clearance blanking.The blanking principle,the die structure,the characteristics and the application field of the four processing methods were introduced and it could be a reference for selecting the blanking process method in practical production.
