Abstract

“Quality improvement by using Taguchi Method in Disk Manufacturing” is the title of this project. This project was implemented to employ the Taguchi Method approach in the disk manufacturing, where an actual production shop-floor performance will be analyzed through Taguchi Method and as a result, alternative solution will be proposed in order to improve the product quality, efficiency and to enhance the performance of the manufacturing system. The company that has been chosen is Ohara Disk Malaysia Sdn. Bhd (ODM), located at Merlimau Industrial Zone, Melaka. The scope of this project focused on the section which Awa (bubble in disc) reject rate in the production shop floor. In conducting this project, a methodology based on the Taguchi design was used for achieving the objective. In the planned project flow chart, factory visit was carried out for observing the production system. From the visit, some necessary data regarding the production flow of whole system was collected. The data collected from the previous studies in the same company together with the one from textbooks, journals, and internet was use as additional input into the newly collected data from the latest visit to the company. Based on all the data collected, the experiment was conducted using the Orthogonal Array design to find optimum solution of the problem. The analysis was done to find the best combination of parameters and factors in order to achieve the research objectives.
