You can produce a parking token by two alternative methods. First, cut a 3/8 inch diameter billet to a length of 3/8 of an inch, and then closed-die forge it to the final size and shape (1\" diameter). Second, you could start with a sheet of material, and stamp it to the final diameter and coin it to the final embossed shape. Compare the energy needed and waste produced by the two methods.

Solution

The first method second method

1. The no. of operatkons are three The number of operations are two

cutting, Die forge and shape Stamp and emboss,

2. Energy consumed will be high since there are The energy consumed will be less only

cutting - a shering operation two operations are involved

Die- forge - a heavy machinery Stamping - takes more or less the same Shaping takes less power power as cutting /shearing as the other method

Shaping takes same power as the other method

3. There is not much mateial wastd The blanked sheet of material is the waste but can be recycled.
