Engineering has provided manifold benefits to human beings. It has been able to make our life swift, easy and luxurious. Taking things apart and changing them into something more usable, advanced has always been an important method applied by the engineers to figure out the way in which the engineering of that thing actually works. This method is also known as reverse engineering.
Reverse engineering is the method of knowing the technological principles of object, device or a system through analysis. It is a process in which an object, device or system is broken down carefully to their most basics forms to determine how every part has been created to work unanimously as a single, functional unit. It involves analyzing of objects in detail so as to create similar or new programs that use the same principle without making use of the original substance.
Reverse engineering is an important technique because it allows people to know how technology works and how it can be maximized and utilized. Improvements can be done by making better inventions and innovation of the functional technology. Reverse technology was first used for the analysis of hardware for commercial and military benefit, it was used during the times when original methods to manufacture these technologies were tough to comprehend. The aim of this technology is to infer design decisions from the end products without having any information about the methods used in its original production.
Similar techniques are also being researched to apply in legacy systems to replace incomplete, incorrect and unavailable documentation. The concept of reverse engineering is more applied as technology seems to advance. This engineering helps in changing the previous failures into success. Prototypes of earlier inventions that have been unsuccessful can be revived again for their errors and are modified and analyzed.
Reverse engineering is used for variety of reasons. With the popularity of computer aided designs (CAD), this form of engineering is used as a viable way to make a 3D virtual model of an available physical part for use in CAD, CAE, CAM or any other software. This form of engineering involves measuring an object as a 3D model and reconstructing it thereafter. The physical objects are measured using 3D scanning technologies like laser scanners, CMMs, computed tomography or structured light digitizers.
In reverse engineering, several software which facilitate its users to get complex parametric models through the scanned data easily.
This software comes with a set of tools that are particularly designed to fulfill the unique needs of reverse engineering while making sure that the completed redesigned model is built keeping the user defined needs in mind.
A few examples of these software include:
Rapid form is used for creating parametric CD models from three dimensional scan data. It is utilized to create fully surface and editable solid models right from the 3D scan data.
Geomagic Studio 10
Geomagic Studio 10 gives the most instinctive and easiest interface to create Non-uniform rational B-spline models from the scanned data. This software helps in generating non parametric models and free form shape models.
The benefits of reverse engineering in CAD are numerous and are used to make highly finished design models.
