Abstract

The main objective of this project is how to implement the total design approach to produce the product. Besides that, the objective also stated that the fabrication or developments of Slitting Sheet Metal Machine need to be achieved by the end of project schedule. In this study, there are three approaches used which is Pugh matrix, Failure Mode Effect Analysis (FMEA) and Design for Manufacturing Assembly (DFMA). Pugh method is a design process to select the best design concept according to customer requirement. In addition, the design process has several methods which is Pugh method, Pahl and Beitz’ model, Otto and Wood methodology, Ulrich and Eppinger and French model. Finite Element Analysis (FEA) is used to collect the data of analysis result. This data will show the weakest part that needs to be improved either on the material or the design. Plus, the material chosen must consists of several specifications such as resistant to force, absorb the vibration and high pressure under stress load. After that, the integration between Pugh’s matrix and Failure Mode Effect Analysis (FMEA) method is used to improve the designs of blade and shaft. There are three concept designs discussed in this section. The result from the approach is to select the best design of blade and shaft that is potential failure to the product. Lastly, the approach used is Design for Manufacturing Assembly. In this approach, the latest design from two designs approach which is Pugh’s matric and FMEA method is analyzed in DFMA method. The objective using DFMA method in this study is to reduce the part and manufacturing cost. The output of the project is expected to be required to meet the objectives set. The result is fabrication of slitting sheet metal machine for wire mesh and testing it to achieve the process of slits the wire mesh. After complete the fabrication process, the machine is sent to TR Technology Sdn, Bhd for the workers used in their productions line. In addition, the expected outcome should also meet the needs of customers and gain customer satisfaction. It will be evident that the methods used by researchers suitable for producing a product.
