In parts I and II of this series, we identified four primary process factors that influence the cost and quality of progressive dies: Station number factor, F_n Moment balancing factor, F_b Strip stability factor, F_s Feed height factor, F_h. Mathematically evaluating these factors and their corresponding weighting factors - w_n, w_b, w_s, w_h - derives an evaluation score (E_v) for ranking several feasible strip layouts: E_v = (w_n × F_n) + (w_b × F_b) + (w_s × F_s) + (w_h × F_h) The designer or process engineer selects the weighting factors by determining each evaluation factor contributes to the final evaluation score. The final evaluation score has relative meaning for different feasible strip layouts producing the same part. Therefore, it can be used to find the best solution for processing the particular part.
