I came across a nice resource on fine blanking. A specialist technique for producing components from steel strip in the pressings or stampings industry, it's well worth bookmarking.
By way of an introduction:-
Fineblanking, as a process, is a marriage of a very specific type of hydraulic press that has three motions and specially designed tooling. The combination of the fineblanking press with fineblanking tooling creates parts with fineblanking's hallmark fully sheared, straight cut edges. It also produces parts with small holes and thin web sections relative to material thickness, parts with excellent flatness, and parts that have very little dimensional variation from the first part through the millionth part and beyond.
