【正文】 gine air filter manufacturing process by process analysis, it includes blanking, drawing three times, two times drawing, deep drawing, trimming process. After analysis the blanking and drawing the first time, plete with pound die, while the other is not drawing but to calculate the correlation dimension, focusing on the pound die, at the same time give parts of the die of the detailed design to solve the problem of the calculation of blanking and drawing. Generation of assembly drawings and related parts just map. KEYWARDS： die ， deep drawing ， assembly drawing ， parts drawing i 目錄 摘要 ......................................................................
