The machine support bracket illustrated alongside must be manufactured from 5 mm low-carbon, commercial quality steel (AISI 1018 steel) using a turret press with plasma profile-cutting capability, followed by press brake operations. The dimensions of the blank prior to bending are 20 x 15 cm. After bending the horizontal base is nominally 5 cm wide and the vertical wall is 10 cm high, tapering down over a horizontal length of 8 cm to a height of 4 cm. The vertical slots are 6 cm long and the horizontal ones 7.5 cm long. All four slots have a width of 1.25 cm wide. (a) Estimate the required press force for the bending operation. Clearly state your assumptions. (10) 20cm 15 cm
