<Li> Continuous grain flow </Li> <Li> Finer grain size </Li> <P> "Cogging" is the successive deformation of a bar along its length using an open - die drop forge . It is commonly used to work a piece of raw material to the proper thickness . Once the proper thickness is achieved the proper width is achieved via "edging". "Edging" is the process of concentrating material using a concave shaped open - die . The process is called "edging" because it is usually carried out on the ends of the workpiece . "Fullering" is a similar process that thins out sections of the forging using a convex shaped die . These processes prepare the workpieces for further forging processes . </P> <Ul> <Li> <P> Edging </P> </Li> <Li> <P> Fullering </P> </Li> </Ul>
