Abstract

Reverse engineering has been increasingly popular researched and applied widely in the field of quick product development, especially 3D design from available products with support of computers. This technology plays an important role in designing products according to available models without corresponding CAD models. In previous time, taking samples of a product required measurement and sketching (traditional sampling) that gave inaccurate results, wasting time and being difficult for complex part. Nowadays, with support of digital technology, sampling of these parts is highly accurate; the CAD model can also be edited if needed. Implementation includes sampling to build the mode, evaluating the error, designing and manufacturing the model. This paper will present application of reverse engineering on sampling of computer mouse case and mould core design to manufacture this product. Processes include sample scanning, data processing, complete design of pressing mould, error evaluation and conducting experiments to manufacture mould core. The result of model for the computer mouse case ensures technical requirements.
