2.2 PRODUCT FUNCTION
- With your selected material, how is your material
compatible with product geometry and
manufacturing processes?
- What is the normal applied load to the material?
Can your material take such load?
- What is the normal ambient conditions to your
material?
- With your selected manufacturing process, how is
your process compatible with the product
geometry?

2.3 MANUFACTURING COST
![Page 8: Amp’s cut](https://reader033.fdocuments.us/reader033/viewer/2022060203/559ec1df1a28ab4e038b46eb/html5/thumbnails/8.jpg)
Total manufacturing cost (TMC) = Material (M) + Tooling (T) + Processing (P)
The material costs per part can be calculated as:
Let M = total materials costs (raw, bulk)
q = production quantity
The material costs per part, cM is
cM = M/q = (cost/weight x weight) / number of parts
Let
cw = material cost per unit weight
wp = weight of finished part
ww= weight of wasted material, scrap
a = ratio of wasted material weight / finished weight
= ww / wp

cM = cw wp (1+ a)
cM acrylic = 140 baht /kg * 0.2 kg/part * 1 0.25
= 35 baht/part
cM steel = 20 baht/kg * 0.1 kg/part * 1 0.05
= 2.1 baht/part
cM = cM acrylic cM steel
= 37.1 baht/ part

The processing cost per part, cP is
Let
ct = cost per hour, (machine rate +
labor)
t = cycle time (hours per part)
then cP = ct t
cP = 20 baht/hr * 0.30 hr/part
= 6 baht/part

The tooling cost per part, cT is
cT = T/q
T= total cost of molds, fixtures
per product run
q= number of parts per run
cT=0

c = cM + cT + cP
C = 37.1 + 0 + 6
C = 43.1 baht/part
