Abstract
Cutting various types of material using laser has been highly preferred in industries over the decades due to its benefits in terms of contour precision, quality, productivity and flexibility compared to conventional machining. The CNC automated laser cutting machine often comes in a large size, heavy weight and demands a high capital investment. This shortcoming of the machine has limited its application and rarely used by small and medium- scaled industries as well as non-manufacturing sectors. This thesis aims to develop a small- scaled laser cutting machine which is light and portable at an affordable cost. Different types of lasers, mechanical systems and electronic firmware were reviewed. The proposed laser cutting machine utilized a 5.5W diode laser, H-bot mechanism, aluminium structure, Arduino microcontroller and open source software. The model was illustrated in CAD software besides necessary simulation and calculations were performed. The finished prototype had a working area of A5 size, weighed 1.7kg, cost RM 1230.85 and was able to cut the tested materials, which include thermoplastics, Nomex, polyproprene, wood, cloth and paper. Modification on the mechanical structure especially the slider assembly was suggested for further improvement. This design had a bright prospect in enhancing the industrial performance in small and medium-scaled industries, promoting research and prototyping; and encouraging more creative individuals in society.
