Penyelidikan ini membentangkan tentang sistem pemantauan untuk penebukan komposit yang memeriksa keadaan bit gerudi menggunakan kamera mikroskop digital bersama sebuah sistem komputer yang dilengkapi teknik pemprosesan imej untuk mengesan haus sisi. Projek ini bertujuan untuk menyumbang satu sistem baru dengan memperkenalkan satu sudut pandangan kamera yang baru untuk mengesan haus atau perubahan pada bentuk bit gerudi khususnya bahagian sisi supaya dapat menentukan jangka hayat alat. Imej bit gerudi yang telah haus ditangkap dan dianalisis menggunakan perisian MATLAB untuk mengukur peratus haus. Sudut pandangan kamera ditentukan berdasarkan prinsip pencerahan dan ditetapkan pada sudut 45 darjah. Kemudian, imej yang telah ditangkap melalui pra-proses imej dan dianalisis untuk mengesan haus dengan menggunakan teknik cantuman imej. Semasa pra-proses imej, imej warna sebenar ditukarkan kepada imej perduaan dan pengesan tepi ‘canny’ diaplikasikan untuk mengesan batas sisi. Operator morfologi seperti pengembangan, pengisian, penutup dan penghakis diaplikasikan untuk membentuk semula bahagian sisi untuk memastikan bentuknya sama dengan bahagian sisi yang sebenar. Akhirnya, imej panduan dan imej bit gerudi haus dicantum bersama menggunakan teknik Prinsip Komponen Analisis dan peratus haus dikira. Projek ini terbahagi kepada dua bahagian iaitu bahagian perkakasan dan bahagian perisian. Untuk bahagian perkakasan, satu tetapan direka dan diinovasi manakala untuk bahagian perisian, satu kod MATLAB telah ditulis untuk memproses imej yang ditangkap dan mengira peratus haus. Algoritma yang digunakan adalah berpandukan daripada ‘Math Work’ dan diadaptasikan ke dalam projek ini untuk memuaskan objektif projek. Di penghujung projek ini, perubahan pada bahagian sisi dapat dikenal pasti berdasarkan pembandingan dengan imej panduan dan peratus haus dapat dikira. _______________________________________________________________________________________________________ This research presents a monitoring system for composite drilling that inspect the condition of the drill bit using a digital microscope camera with a computer system that implies image processing method for flank wear detection. This project aims to provide a new system by introducing a new camera view angle that can detect wear or changes in the drill bit geometry specifically, flank region in order to determine the tool life span. Images of wear drill bit are captured and later on analyse using MATLAB software to measure wear percentage. The camera view angle is determined based on the principle of illumination and decided to be at 45 degree view angle. Then, the images taken undergo image pre-processing and further analyse to detect wear by image fusion method. During the image pre-processing, the true colour image is converted into binary images and canny edge detector is applied to detect the flank boundary. Morphological operators such as dilation, flood fill, closing, and erosion is then applied to reconstruct the flank region to make sure it is approximately the same shape as the actual flank region. Finally, the reference image and the wear drill bit image are fuse together using Principle Component Analysis (PCA) method and the wear percentage is calculated. This project is divided into two parts which are hardware and software part. For the hardware part, a setup is design and innovated meanwhile for the software part, a MATLAB code is developed to process the images taken and calculate the wear percentage. The algorithm used is referred by Math Work and being adapted into this project to satisfy the objective of this project. At the end of the project, we could observe the changes in the flank wear area as compared to a reference image and the wear percentage can be calculated.
