Reverse Engineering

What is Reverse Engineering ?

Let us start with an example. One day you get into your garage and find on the workbench a 'black box'. Stricken by curiosity, you build up an urge to discover what it 'is' and what it 'does'. You start with an inspection of the box's dimensions, color. Then you try to find its purpose and then how it operates. Not satisfied, you try to open it, break it apart, piece by piece in an attempt to understand what each component does and build up a pattern of how they would all interact together as one system. Finally you reach the end of your inquisition. You now fully (or partially) understand the box. This very approach is termed as Reverse Engineering.
Reverse engineering, also known as back engineering, is the process where a man-made object is dismantled completely to reveal its architecture, design or to extract knowledge from the object about its functioning and structural integrity.

Why do you need Reverse Engineering?

There might be innumerable reasons to adopt reverse engineering process. Some of the common cases are as follows:

  • The original manufacturer of a particular product no longer produces it. In some cases, situations arise where original manufacturer ceased to exist, but a customer needs the product. Then there are cases where an original supplier is unable or unwilling to provide additional parts
  • There is inadequate documentation or no documentation at all of the original design
  • To enhance and strengthen the good features of a product based on its long-term usage
  • To analyze the shortcomings of the product, thereby exploring new possibilities to improve product performance and features
  • To update obsolete materials or replace outdated manufacturing processes with more current, less-expensive technologies
  • The CAD model is not sufficient to support current manufacturing process; hence creating 3D models
