Abstract

This project entitled ‘The Determination of Inconsistency Quality Cutting of Composites Part at Abrasive Waterjet Trim Process’ conducted at Asian Composites Manufacturing Sdn. Bhd. (ACM). In essence, this project is carried out is to determine the factors which contribute to the defects that irregularly increased from time to time as well as implement appropriate solution and increase the quality of composite part. The composites part encoded as 116A85120-FD is a fuel door part of 737 Fixed Leading Edge (FLE) of Boeing aircraft was selected in this study. In a way to determine the factors that may contribute to the composites defects, Plan-Do- Study-Act (PDSA) cycle have been using with the aid of QC tools that used to analyse, monitor, control, manage and improve a process throughout this study. In addition this project also has a review about the composites materials and abrasive waterjet machine used at the company. Besides, Process Failure Mode Effect Analysis (PFMEA) technique also being used to recognize and evaluate the potential failure of the process. Throughout the using of QC tools its indicates that machine edge delamination has emerged as the main deformities of fuel door of composites panel. Furthermore the result of PFMEA used shows the surface resin starvation is the most prevalent causes that contribute to the arises of machine edge delamination problems. Subsequently, it is recommended that for future work undertaken to identify the recommend actions that should be taken to minimize the possible causes in PFMEA.
