Abstract

The main objective of every manufacture is to multiply the profit gained from the manufacturing activities and it is to be done by reducing the cost of production. Design for Assembly (DF A) concept is a procedure that developed to be used in systematic way to determine the problem that may arises in assembly. It is one of the most powerful tool for reducing manufacturing costs. In this respect, several DF A methods are introduced by expert in this field. Among all of the design for assembly methods, Hitachi Assemblability Evaluation Method, Lucas DF A Method and Boothroyd-Dewhurst Evaluation Method are three well-known methods. In this thesis, study towards the DF A evaluation methods has been done. A selected product design is evaluated and redesigned by using one of the DF A method seeks to minimize the assembly cost and time. Basically, it is done by reducing the number of parts and ensuring easy assembling for the remaining parts. This case study is carried out starting from the literature study and them on how to implement the three different DF A methods. It is hoped that in this case study, all users become familiar with philosophy of assembly, provide useful companion and understanding of the advantages and disadvantages among the DF A evaluation methods.
