Design, Fabrication and Performance Test of Arduino-Based Automatic Cutting Tool for Coconut Shell Charcoal Briquettes

Abstract

This study aims to design and fabricate automatic briquette-cutting equipment that uses Arduino technology. This is necessary to ensure that the briquette-cutting process is more efficient and rapid, with accurate cutting results and a uniform dimension. The research processes include design criteria, morphological matrix, product concept, decision-making matrix, geometric design selection, fabrication of the selected design and performance testing. According to the decision-making matrix, concept 3 emerges as the most appropriate concept because of its numerous advantages, such as its robust structure, ability to endure vibration, dependable performance, readily accessible components and superior precision in cutting briquettes. The study's findings demonstrate that the autonomous cutting tool has exceptional performance. Using the proximity sensor's input, the Arduino can precisely command the servo motor to cut the briquettes using the cutting plate. The initial performance test yielded a cutting consistency of 68%. Nevertheless, the second performance test yielded a cutting consistency of 78%.
