V12 Crankshaft Mold

Recommended Posts



Im designing a  v12 cross plane crank mold

dimensions of the mold  1000x800x400mm and total weight of the moving mold will not exceed 10tn

Diameters of cutting tools 25mm -200mm

drilling 1mm-20mm

estimated life cycle tools 50-60h

carbon stylus 1mm -8mm =30-40E

  the strength requiremenent of a crank the material I choose is mild carbon steel 0.44C Si0.33 Mg0.8 Cr0.8 , any thoughts

density of steel 7870kg/m3

mass of mold =0.32m3x 7,870kg/m3 = 2,518.4 kg

price 8,9E/kg

  mass x $ = 2,518kg x8,9E/kg= 22,413.76E total cost of moving mold

for the mold there are  5 subsequent steps, why 5 steps and not one for the final mold?
