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.

Keywords: CADCAM; coin manufacturing; CNC; rapid prototyping; stereolithography; computer-aided design; CAD; computer-aided manufacturing; CAM; computer numerical control; coins; Chinese characters.
