Question 2. It is reduced to 80 mm with forging by stacking a part with a height of 120 mm and a
diameter of 75 mm. The friction coefficient between the workpiece and the mold is 0.13. The flow
curve of the workpiece is defined by a strength coefficient of 165 MPa and a ping-top of
0.24. Calculate the force during the process at the moments given below and obtain the
force-workpiece height graph
(1) as soon as it reaches the flow point (flow unit shape change = 0.002),
(2) height h = 115 mm,
(3) height h = 110 mm,
(4) height h = 105 mm,
(5) height h = 100 mm,
(6) height h = 95 mm,
(7) height h = 90 mm,
(8) height h = 85 mm,
(9) height h = 80 mm,
1. In the manufacture of automotive-body panels from carbon-steel sheet, stretcher strains (Lueders
bands) are observed, which detrimentally affect surface finish. How can stretcher strains be
eliminated? Explain with appropriate sketches. Also discuss how wrinkles in a deep drawing operation
can be eliminated.
