article description
Shear cutting is used to separate a sheet metal into two parts. During the cutting process, the material is deformed by two moving parts until its formability is exhausted. When a material is sheared, a burr deformation can often be observed on the cutting edge. Due to different disturbing effects, the burr must often be deburred before the next process of machining.
