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.

A long, copper strip, 500 mm wide, 3 mm thick, was found to have 450 MPa yield stress. The strip is required to be rolled in order to reduce its thickness. In the rolling process, the width remains practically unchanged while the rolls apply pressure in the thickness direction. An additional tension of 150 kN is applied in the longitudinal direction to assist the forming process. Ignoring the change in the width and any friction effects, determine what roll pressure would just cause deformation: according to the Von Mises yield criterion. according to the Tresca yield criterion. Material properties in the elastic range: E=75 GPa, v=0.4. (a) (b)
Question 3 A rolling operation on a 250 mm wide, 8 mm thick, 1112 cold rolled steel takes place using hardened steel rolls with a surface finish of 0.03 um. The rolls have a diameter of 350 mm and rotates at 115 rpm. The final thickness of the plate is 6 mm and the entry speed of the plate is 1.8 m/s. Calculate: 3.1 The minimum coefficient of friction required, that will make the rolling operation possible. 3.2 The required roll force. 3.3 The position of the neutral point, xn 3.4 Indicate, using a sketch, the neutral point showing all relevant notation and dimensions.
Hi, can you help me solve the attached problem where I am asked to calculate the total force to obtain a component from an initial aluminum bar by using the manufacturing process of cold rolling.

Q4: Proof the validity true strain additive feature in compression deformation?
A hot/cold rolling setup is shown right. The operation first hot rolls a 3/8” thick plate, 12” wide (w), of6061 Aluminum, to an intermediate thickness, then finally through cold rolling, down to 1/4” thick plate.The friction factor μ is assumed to be constant at 0.15 for the hot roll, 0.12 for the cold rolling stage. Thefirst set of rolls operate at 50 RPM. Also ignore any width increase during rolling. CW=13% or .13 What is the plate thickness (mm) prior to the last rolls, t1, if the last set of rollers perform cold work reduction listed below at .13 or 13% Note that 9.52 mm is equal to 3/8 of an inch.
Assume you are bending a 3/16” thick rolled plate of Al 6061-T6 at a 90-degree angle. The initial bend radius (after the part is bent in the press brake) is 0.35”.
