Reverse engineering, as the name implies is an engineering process going in reverse. The process has in resent times emerged from the shadows of engineering science to become common in many organisations today.
To study engineering can be difficult, especially transforming theoretical knowledge into practice. To address this issue, Otto and Wood have developed a reverse engineering and redesign methodology, suggesting that it can be used as a tool in the process of learning mechanical engineering and design. The aim with this report is to evaluate this statement, emphasizing on the reverse engineering process and evaluating its usefulness as an educational tool. In order to fully understand the process, two cordless screwdrivers will be reverse engineered, functioning as an example throughout the report. A theoretical background of the process will be introduced, including descriptions concerning the different steps and their encompassed tools, tests and methods…
