Wood carving is a form of working wood by means of a cutting tool in one hand or a chisel by two hands or with one hand on a chisel and one hand on a mallet, resulting in a wooden figure or figurine, or in the sculptural decoration of a wooden object. This kind of industry is very popular in Malay culture either in agriculture or craft. The design or profile of wood carving can be varying based on how a customer required. As the wood carving industry is mostly used manual or conventional method in the production line, it was interested to find out the limitation of the traditional method, and thus propose a suitable process as the improvement method that to be used. For this study, laser machining had been chosen as the alternative method in order to cut the wooden product based on the advantages can be achieved by this method. In order to achieve the aims for this study, a visitation to a wood carving industry was done to search for more information about the conventional process. The main limitation by using conventional method was poor surface finish. Laser cutting had been proposed as the improvement method and design of experiment (DoE) was used to approach for this study. The parameters used in this study are laser power, cutting speed, assisted gas pressure, and focal length distance. The cut quality such as surface finish and kerf width are investigated to find out the optimum parameters for laser wood cutting. The optimum parameters to achieved good surface finish and narrow kerf width was using laser power 2.2 kW, cutting speed 1500 mm/min, and gas pressure 9 bar.
