In a blanking operation to produce steel washers, the maximum punch load used is 3 × 105 N. The plate thickness is 5 mm and the percentage penetration is 25%. What is the work done during this shearing operation?
Solution:
A cylindrical block is pressed using open-die forging. At any instant, the block has a diameter (D) of 30 mm and a height (h) of 60 mm. The coefficient of friction (μ) is 0.5. The force acting at that time is 2200 N. Find the flow stress of the material. (Take Kf = 1 + (μ*D/h), Kf = forging shape factor)
Solution:
The coefficient of friction is an important factor in forming processes and plays a crucial role in calculating the forces involved. The typical range of the coefficient of friction is:
