Modern Blanking and Piercing Dies

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Punches and dies are made in such a variety of designs and for so many different purposes that it is difficult, if not impossible, to treat the subject of die construction and design in a general way and present fundamental principles which can be applied universally in the art of diemaking. For that reason, diemakers in describing their methods and practice have almost invariably confined their articles to specific die designs instead of attempting to deal with the theories of the subject. Contributions of this kind, relating to dies which have been in actual use, are, undoubtedly, of great practical value because they show what has been accomplished and often suggest a method or design that can be used for other classes of work.
