Abstract

This project is to demonstrate the use of Design Manufacture and Assembly (DFMA) in product development process. In this project, slicing machine is chosen as the product to use in the process of DFMA. The objective of this project is to reduce the number of component of the cutter as well as to analyse the materials and processes involved in the production of slicing machine. In addition, the method of DFMA is chosen due its ability to calculate the cost of labour required in the manufacturing process. To ease up the analysis, Boothroyd-Dewhurst DFMA software was used. This software is chosen due to its effectiveness in reducing the components in a product and which is convenient to be utilized by designers. The results of this study are the new design of slicing machine in which 26% improvement from original design in DFA index and the cost of the new design is 45.27% lower than the original design from RM9500.07 to RM5199.07. As for the conclusion, , DFMA is used as the basis for concurrent engineering studies to provide guidance to the designs in designing the product. Besides that, Design for Manufacturing (DFM) was applied to choose the most suitable process and material with the guidance of the shape attribute in the compatibility chart. Plus, Design for Assembly (DFA) stage is a vital tool that can be used to improve the product design. In order to improve the project, several recommendations has been planned which is a research on the potential of geometry interface part or components data to be linked to the software can be conducted. This project are recommended to be preceded into the fabrication stage. Plus, the material chosen must consists several specifications such as it can resist force, temperature and pressure.
