| Summary: | This study is an approach to investigate the viable impacts of screw manufacturing and
to choose the suitable material for selected manufacturing process of screw by putting
environmental aspects as important as economic aspect. The parameters involved were
types of material and manufacturing process of screw that using the available data of
environmental and production volume. The two different manufacturing approaches
being evaluated were machining and forging process. The types of material concerned
for forging process encompassed low carbon steel, alloy steel stainless steel, and
aluminium alloy. On the other hand, for machining process, the material being
considered in screw manufacturing were cast iron, low carbon steel, alloy steel, stainless
steel and aluminium alloy. The information of environmental impacts that generated
from SolidWorks Sustainability tool and screw production cost were calculate using
Manufacturing cost model, both information was used in Analytic Hierarchy Process
(AHP) analysis to obtain local priority of economic and environmental impacts. Then,
the ranking of global priorities with combination of local priority from economic impact
and environmental impacts had enabled the determination of appropriate material used
for those selected screw manufacturing process. As result, low carbon steel was chosen
for forging process whereas cast iron was excelled in machining process, at the same
time, stainless steel was not suggested to be used in all two processes. |
