Evaluation on the Plate Laminated Method Using 3D CAD/CAM/CAE System for Construction of Canoe Hull

Generally canoes are the most popular boat in leisure activity on the water. Recently, its demand has been continuously increased, furthermore, the recent users hope that those canoes are high degree of quality, mass production and cheap cost etc.. For solving this problems, the wooden canoe manufactured by the strip construction method has been commonly used for leisure activity of various field. However, this method mentioned above is not suitable for mass production which needs a effective operation, managements as well as cheap product cost. In this paper, the new construction method, called the piling-up laminated construction method which is composed with new both 3D design system and manufacturing technology to satisfy all the canoe shape accepting previous user's various needs and the need of mass production is studied with using the laminated wooden plates. The manufacturing technology of the laminated plate kit type could be applied flexibly in both the mass production and small production by user's order. Furthermore, the laminated plate kit type compared to the strip construction method could be decreased to about 1/3 the time required for production, manpower and cost. Consequently, it could be verified that the laminated plate kit type was able to make a major contribution to improve the reliability of product.
