A small connecting rod is forged from AISI 1015 steel at 1200oC. Calculate the forging force in a mechanical press at a speed of 200 mm / s when the die comes into contact with the part. The volume of the connecting rod is estimated to be 28680 mm3, and 20% of the starting material is expected to burn off as flash (flash). In the final form the projected area is 3500 mm2 without flash. The width of the flash is 7.6mm around 300mm in circumference.

Forming and Shaping

Metal forming is a category of metalworking process through which the material can be given the desired shape and size by subjecting it to plastic deformation, where the component undergoes bulk deformation process upon application of loads. Unlike the shearing and machining process, the material does not undergo up to a failure point as indicated in the stress-strain curve. Hence, the stresses induced during the forming process are greater than yield strength but less than the failure strength of the material. The process does not lead to the loss of material, so it can be said to be an economical process. During forming, the material is subjected to tensile forces, compressive forces, bending, and shearing loading conditions. The material should possess the property of ductility to undergo the forming process.
