This paper is about the hands-on, practical aspects of making use of CAD/CAM, told from the experiences and observations of a user. Issues covered shall include the errors made due to large-screen images in relation to actual size and the considerations that need to be taken into account with on-screen measurements to achieve the desired measurements on the finished product. In addition, the paper will present a resumé of experiences and observatons on using CNC matching of wax and the limitations of the machining process. Finally, the paper will look at comparative Rapid Prototyping systems and materials in relation to casting.
