【正文】 ing process analysis and posite mold design. According to the design of posite die stamping steps for process analysis to determine the stamping process, according to the calculation rules to calculate the blank size, punch, punch die size and pressure. Calculation is pleted, in accordance with the calculation results are plotted mold parts dimensional maps, engineering drawings and die assembly drawings. Through the above process to finalize the thin groove notching, blanking posite mold design. Keywords: Sheet metal； stamping； CAD； UG； pound die 目 錄 摘 要 ..............................................................................................................................
