Abstract

It is now widely accepted that the majority of the cost involved in assembly is determine at the earliest design stage. Although it is obviously important to keep assembly cost as low as possible, in this project, nail clipper is being chosen as a subject. The main objective is to reduce parts count, where it is a major influencing factor when considering the assembly efficiency. DFA method through Boothroyd Dewhurst (BD) Methodology is chosen because of well established technique for cost reduction at the design for manufacture interface. The DFA method starts with the analysis to rate each component on its ease of orientation and assembly of an existing nail clipper design. In the original design, six components need to be analyzed to optimize manufacturing cost. Through the methodology, the re-design helps to simplify the design and reduce the part count into three components. From the simplification approach, the cost estimation can be done. It predicts the cost of the product before a great deal of capital resources have been consumed in its design where in this case 50% of parts reduction will help tremendously. This explain the conceptual design using BD DFA helps to identify potential saving that manufacturing people need to be implemented especially in this economic downturn.
