A complete guide to reverse engineering – Learn how it works?
Learn how reverse engineering works
Mechanical engineering has evolved with such as lot of new technologies came. Over the past 120 years, manufacturers all over the world have produced millions of machine products and parts. Due to continual advances in technology, few of these products have remained relevant for more than several years after their releasing initially. However, numerous old parts used in machines have stood the test of time. When the part malfunctions or breaks down completely, professionals of Top Engineering Colleges in Rajasthan replace the component, not the whole device. This process is known as reverse engineering makes replacing these parts possible.
In any given factory or office building, students of engineering colleges in Jaipur are likely to see manufacturing or computing systems comprised of sophisticated equipment. Typically, the parts in question will range in age from new to more than 20 years old. For these systems to remain intact, various different components must be reverse engineered and recreated.
The reverse engineering processes
To reverse engineer a physical product, an organization will typically acquire an example of the product in question and take it apart to examine its internal mechanisms. This way, engineers of private engineering colleges in Jaipur can unveil information about the original design and construction of the product.
When reverse engineering a mechanical product, you start by analyzing different dimensions and attributes of the product in question. For instance, an aircraft, ship, vehicle, computer or piece of industrial machinery. During this analysis, they can make measurements of the widths, lengths and heights of key components in the product, as these dimensions often relate to the product’s performance capacity.
Today, most engineers use 3D scanning technologies to make these kinds of measurements. With three-dimensional scanners, engineers of Top BTech Colleges in Rajasthan can gain accurate readings of the product’s specs and have this information automatically logged in their databases. 3D scanning technologies include industrial computed tomography (CT) scanners, coordinate measuring machines (CMM), laser scanners and structured light digitizers.
After all the pertinent information has been gathered and recorded, an individual can use this data to create computer-aided design (CAD) drawings for subsequent analysis and development. CAD drawings are digital two-dimensional and three-dimensional representations of the products, which they can use to analyze the product’s design. These digital models help to unveil design intent and inform the creation of a reverse-engineered component.
Role of engineers in reverse engineering
Reverse engineering is often required in the development of computer parts due to the obsolescence of parts from prior years. For instance, they might have one product with a unique innovation from two years earlier, but the manufacturer has since gone out of business. To link that innovation to a newer product for convenience and continuity’s sake, the engineering team of top engineering colleges in India will need to examine the obsolete product for its technological makeup.
In order to reverse engineer a PCB, technicians start by examining and identifying the various components of the board. Each board will typically have resistors, capacitors, LEDs, a transistor, an inductor and various other features. The task here is to determine how the layout of these features gives the PCB its unique capabilities.
Before disassembly, the reverse-engineering team will photograph the board up close from the front and back to create a record of the board’s Once the notes and images are collected, the engineers of Engg colleges begin the process of deconstructing the board.
During disassembly, the team removes each part from the board, one after the other. The parts must be set aside for safekeeping and organized in the order they were removed. This way, the board can be reassembled later on, if necessary. In cases where the objective is to replicate the design in question, engineers might test their ability to replicate the product by disassembling and reassembling an existing copy several times over.
With different components removed from the old board, the team then draws up a list of the materials and the order in which they were placed on the PCB. The team will also scan the board’s trace pattern so that they can recreate it later.
The reverse-engineering team may use the pieces at hand and the information collected to assemble a new board. First, they lay out a new board and then install the components in the same order used for the original PCB. Once assembled, the new board is run through a series of tests to determine its functionality. The team will digitally document the results of these tests for future study.
What is the purpose of reverse engineering?
Reverse engineering at the list of engineering colleges in Jaipur provides manufacturers with information about the design of a product or component. When done successfully, reverse engineering provides a virtual copy of the blueprint that went into the original design.
Reverse engineering is perhaps the most accurate way to recreate the designs for items that went out of production decades. In cases where the original blueprints are long since lost or destroyed, reverse engineering is perhaps the only way to bring such products back to life. If they can obtain a working model of an old product, you can typically trace the steps of its design and use those insights to construct a new model, repair a part or improve future products.
