Abstract

This paper shows a detailed study to investigate the Design for Manufacturing and Assembly (DFMA) method to improve the product design process. Through the applied DFMA, the production cost of manufacturing and assembly can be reduced as well as improving the efficiency of the product. Amongst the methods that widely been used in the industry for the product design improvement, the most efficient and reliable way must be identified. A product with many part count numbers will effect the product designing process. This problem commonly occurs in assembly line as the rises of number of tasks, task times as well as cycle times which then affects the production cost. Due to that, the product takes more steps before entering the market. The main objective of this project is to reduce part count number in the existing product design by using DFMA method. This project will compare the product design by using DFMA techniques namely Boothroyd Dewhurst (BD. The approach is by using the software of Boothroyd Dewhurts. Other than that, CAD software has been used for the proposed new design. The CAD drafting tool used is CATIA as it represents the visual of part design in solid view as well as the material applying and mechanical properties of each part drawn. The result of this project can be used and applied in industry in order to improve their design effectiveness.
