2.1 MANUFACTURING PROCESSSEQUENCE

-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/qT= 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
