Abstract
DFMA is a combination between DFM and DFA. Design for manufacture (DFM) is a systematic procedure to maximize the use of manufacturing processes in the design of components and design for assembly (DFA) is a systematic procedure to maximize the use of components in the design of a product. While, the term DFMA is defined as a set of guidelines developed to ensure that a product is designed so that it can be easily and efficiently manufactured and assembled with a minimum laborious effort, assemble time, and cost to manufacture the product. The purpose of this project is to reduce part count and minimize the product cost. Many of the companies outside there were successfully used this technique for product design improvement and product cost reduction. The aim is to propose a new design of computer desktop chassis that is better in design efficiency, total assembly time and cost. The analysis is done by using Boothroyd Dewhurst DFA method. For the result done by using Boothroyd-Dewhurst DFA method, the design efficiency of original design is 6.4% while the improved design is 15.5%. Total reduction of part from 48 parts to 16 parts after has been redesign. The percentage of part reduction is about 66.67% from old chassis to new chassis. The total assembly time has reduced from 462.11s to 154.5s in manual assembly.
