The joinery technique, as one of manufacturing techniques for the wooden furniture, influences the production process, the economic efficiency, and the diversification of design. Especially, the usage of machine tools can determine how much the students can enhance their design expression capabilities during the practice class in furniture design courses of domestic universities, in accordance with whether to utilize the machine tools or not, and how much and frequent to use the machine tools. The study proved that the joinery techniques, based on the high-tech machine, has more efficiencies in the various aspects, including the easiness to manufacture the products, and the diversity of design than the joinery technique, based on the handcraft-only. As the ground of this, this study estimated the time to produce the wooden furniture by machine tools and by handcraft-only, each. Also, this study show the comparison of the features of three different joinery techniques. On the basis of this comparison, this study made the conclusion that the machine-based joinery technique, which is used in the practice class, is the best method to bring the best results in manufacturing the wooden furniture.
