Abstract
The traditional methods of manufacturing coins are studied in three separate projects. In the projects, CAD/CAM, CNC and rapid prototyping technologies are used to upgrade the quality and quantity of coin production. In the first project investigating the use of CAD/CAM and CNC technologies, a case study of an orchid is looked into, while in the second project involving a dragon and Chinese characters design, a relief creation software and a rapid prototyping tool are used. In the last project, a combination of the relief creation software and CNC technology prove feasible as illustrated by an artistic sculpture motif. The projects showed the viability of integrating high technology with traditional practices.
