A different method was presented, which improved the technical analysis for stamping forming of cylindrical workpieces from estimation according to the tables in texts to the precise judgement formula phase. The loop materials were taken to form cylinder wall by plastic deformation as the research object, and the judgement formula were established based on the experiential data, variation rule and the quantitative relationship to solve the technical analysis problems for stamping forming of cylindrical workpieces, including drawing limit, drawing force, blank holding force, drawing times, selection of fillets, blank modification, edge turning of interior holes, as well as the notch or lug formed by direct deep drawing. The drawing process was regarded as a basic rectangular material to digest the rest of the triangular materials in order to find the basic characteristics factor (b/d) lg (b/t) of the loop material deformation. This method formed a complete analysis system to find a solution to meet the practical application of the production from the formula, and could be used as the preparation of computer-based technology applications.
