Int J Adv Manuf Technol (2010) 49:1–12 11 3D CAD system, it will take about one working day to accomplish the same work. Thus, it can dramatically save time and costs and also provides excellent design quality for progressive dies.
The proposed system is only applicable to holes design for the correlating parts which are standard or parameterized parts or assembles such as screws, pins, lifter assembles, standard punches, and dies now. How to utilize the method extensively to design of correlated holes on plates for nonstandard punches and dies which are variable with different product will be studied in the future.
