The following shapes of parts are desired to blanked from a sheet metal of 3mm, half-hard cold rolled steel whose shear strength = 330 MPa. Determine (a) the appropriate punch and die diameters, (b) blanking force.
aragraph v F 1 Normal 1 No Spac... Heading 1 Heading 2 85.00 50.00 25.00 A blanking operation is to be performed to create the part shown below out of 2-mm thick half- hard 405 stainless steel. Provide (a) a drawing showing the punch dimensions; (b) a drawing showing the die dimensions; (c) the blanking force necessary. Note: you will need to translate tensile strength to shear based on the conversion from the text and use material properties from the text as well, tensile strength of 405 can be found in Ch. 6 (Metals).

Temper drying or tempering a quench harden steel part reduces the brittleness of a part. It also reduces the ultimate -------? strength and -------? strength of a part. However the tempering process also increases the materials ----?as measured by the percent elongation.
Which of the following is true about open die forging process? O Forged pieces have accurate dimensions therefore there is usually no need for additional finishing operations such as heat treatment or machining. O Forged pieces have outstanding grain structure and the best combination of mechanical properties. O Forging is carried out at temperature above re-crystallization temperature Forged pieces are small in size since the forging process is incapable of doing large components such as turbine shafts.
If the wrought stock material costs $60 per kg, what is the lost value due to the material removed, assuming scrap is sold for $3 per kg? Assume the density of titanium is 4.5 g/cm3.
