WebPerforating punch to matrix (die) clearances in metal stamping dies have been universally expressed as a percentage of stock thickness, and for clarity should be expressed as percent per side. The old "rule of thumb" called for clearance per side of 5% and is commonly known as regular clearance. Webthrough the sheet or strip material and into a die cavity where the slug or scrap is ejected. Cutting clearances between the punch and die are closely defined and specified. And the process produces a very predictable edge condition on the finished part. Basically, the punch starts out by trying to compress the material, producing a fast startup greyed out
