The Practical Aspects of Reverse Engineering
Reverse engineering is a process in which parts are carefully measured and tolerances are developed prior to generating CAD drawings or models. The most common application for reverse engineering is the reproduction, or modification, of an existing part for which there is no formal drawing.
Today’s CAD programs have made reverse engineering technology a practical tool for creating a three-dimensional virtual model of an existing physical part. That, in turn, has made the use of 3-D CAD, computer-aided manufacturing, or other computer-aided engineering applications easier.
