2.1 MANUFACTURING PROCESS

SEQUENCE

-WHAT IS YOUR PRIMARY PROCESS? WHY

DID YOU CHOOSE THIS PROCESS?

- WHAT IS YOUR SECONDARY PROCESS? WHY

DID YOU CHOOSE THIS PROCESS?

- WHAT IS YOUR TERTIARY PROCESS? WHY DID

YOU CHOOSE THIS PROCESS?

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

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

Thank you

for your

attention :D
