In CAD, a product is first geometrically modelled in three dimensions in a computer and it can be viewed and examined from any direction. This model can then be used for many downstream applications such as manufacturing and analysis. In CAM, numerically controlled machining processes are used for cutting out a prosthetic device of the hand for prosthesis. The paper aims at establishing the basis of using CAD/CAM techniques in prostheses in particular, a review of our present work done in the area of below-elbow prostheses using CAD/CAM. A laser scanning device has been used to capture the geometry of human hands. The algorithm used in processing the images is discussed. The processed 3D data file is then interfaced with a CAD modeller where reconstruction, mirroring, scaling, etc., can be performed. The resultant CAD model is then passed on to CAM, which concentrates purely on producing a "positive core" mould for moulding the prosthetic device.||Source Title:||Annals of the Academy of Medicine Singapore||URI:||http://scholarbank.nus.edu.sg/handle/10635/58025||ISSN:||03044602|
