Development Of A Methodology To Enhance
Design For Assembly.
Masters thesis, Perpustakaan Hamzah Sendut.
Abstract
Assembly is the activity in which the activities of design, engineering, manufacturing,
and logistics are brought together to create an object that performs a function. Design
for Assembly (DFA) is an approach that addresses product structure simplification,
where the total number of parts in a product is a key indicator of product assembly
quality. The objective of this research is to develop a methodology to help the designer
improve product design and development. The two main concepts that are central to the
development of Design for Assembly (DFA) method are firstly how to make
enhancement of DFA, and secondly how to develop an evaluation system for DFA. The
enhancement of DFA is characterized by a robust procedure to improve product design.
a reliable method to solve problems in design for assembly activities and the ability to
increase ideas in product design. An integrated framework and a software
implementation are developed in order to realize the research objective. The integrated
approach is called 'Enhanced Design For Assembly' (EDFA) and consists of the
principles adopted from the Hitachi AEM, virtual manufacturing system and assembly
principles and guidelines. From the case studies that have been carried out using the
EDFA approach the results showed that it can minimize assembly complexity, reduce
the overall assembly cost and reduce the number of part and component in product
development and improvement. The software "EDFA' is easy to use and helps the
designer's work in product design development and improvement. The comparison of
EDFA method with Boothroyd-Dewhurst shows the capability of producing good
results.
