<strong>DFMA</strong> <strong>as</strong> <strong>Applied</strong> <strong>to</strong> <strong>the</strong> <strong>Swingline</strong> ® <strong>747</strong> Desk<strong>to</strong>p Stapler<br />
The estimated bending die cost, <strong>as</strong>suming $40/h for die making, is<br />
Cost <strong>of</strong> embossing die:<br />
= Cds + ( Mpo + Mpn) * 40<br />
= $2397.92 = $2400<br />
Cds = $255, L = 80 mm = 8 cm, W = 26 mm = 2.6 cm,<br />
Mpx = 0.13 Nsp<br />
Mpo = 23 + 0.03 LW<br />
Mpc = 8 + 0.6 Pp + 3 Np<br />
Therefore,<br />
Mpo = 23.624<br />
Rectangular embossing<br />
Mpx = 4 *(0.13*3)<br />
= 1.56<br />
Circular embossing<br />
Mpx = 2 * (0.13 * 1)<br />
= 0.26<br />
Total<br />
Mpx = 1.82<br />
Mpc = 8 + 0.6 * 7.8 + 3 * 6<br />
= 30.68<br />
Cost <strong>of</strong> embossing die is,<br />
= Cds + ( Mpo + Mpc + Mpx) * 40<br />
= $2500<br />
