FE simulation of a 4-Stage Forging Process
The production of gudgeon pins (the pins that hold together
the two halves of a hinge) can be visualised well with the help of a
finite-element mesh.
The grid distortions produced during the various process
stages agree very well with experimentally observed distorted grids.
Stage 3: Backward Extrusion
The indented slug is backward extruded leaving a cup
shape.
