a). Briefly explain the rolling process with a neat diagram. b). Differentiate between hot working and cold working of metals.

2)

List the four types of loads (or stresses) involved in the forming of metals

Name, draw a neat sketch and explain why each of the following designs ofrolling mill are used instead of a basic two high rolling mill.i) A mill consisting of four rollerii) A mill consisting of six or more rollers

A 1-in diameter hole is to be punched through a 1/8-in thick annealed titanium-alloy Ti-6Al-4V (grade 5, annealed) sheet at room temperature. Estimate the force required for the punching operation. Show your work and list any values you reference/use. Hint: Use the equation F=T*L*Shear Strength

List factors affecting metal forming performance

3) Forging: A cylindrical specimen made of annealed 4135 steel (K = 1015 MPa, n = 0.17) has a diameter of 150 mm, and is 100 mm high. It is upset between dies to a height of 50 mm at room temperature. Calculate the work done for 2 cases: a) Ideal (frictionless) b) Friction, where the coefficient of friction is 0.2. Set up on paper and solve using software. Be careful with units.

please very urgent with count the number on the graph i wil give u good feedback

Hand written plz a billet before and after hot forging from an initial size of 2.5 mm x 2.5 mm x 25 mm to 5 mm x 1.25 mm x 10 mm. This is accomplished by using a flat-face drop hammer. Sticking friction can be assumed. For the rate of deformation and the temperature, a flow stress of 18 MPa can be assumed. a) Find the force necessary. b) Find the work required. (Remember that work=fFdL and that F changes with L.) 1.25 mm 25 mm ✓ 2.5 mm 2.5 mm 154 25 mm 5 mm
