Blanking Sheet Metal with Rule Mark Dies.

1994

Authors: W. Whitecotton

With all this new technology available, it seems almost odd to suggest that a method of piercing and blanking that was developed in the 1800s has merit in today's world. This is, however, just what this article is about. The Rule Mark process is a modification of an old, thin-blade cutting method first introduced in the early 1800s. Because it lacks 'high-tech flash,' this process is probably one of the ...
