has studied the shear deformation properties and the damage behavior on both low and high strength steels using the conventional shearing die
. They found that the thickness clearance is critical in trimming high strength steels.
The cutting movement at the end point of the contour is conducted by shearing die
with the support of hydraulic cylinder.

The process can be used for roll forming, tube bending, drawing, forming and swaging dies/blocks, piercing and shearing dies
, core pins for aluminum, expanding dies, extruding and bending dies, and many others.
For rapid changeover of shearing dies
, Atlas also installed T-tables that allow Caterpillar to prestage the upcoming tooling while the shear is running.
