What Is Reverse Engineering? All About Reverse Engineering

DALIAN, China - Feb. 24, 2021 - PRLog -- What Is Reverse Engineering?

Reverse engineering is the process of examining existing products to determine detailed information and specifications to understand how they are manufactured and how they work. For example, many old parts used in the machine have withstood the test of time. When a component fails or is completely damaged, the component can be replaced instead of the entire device. A process called reverse engineering makes it possible to replace these parts.

For mechanical assembly, this usually involves disassembling, then analyzing, measuring, and recording the parts. Reverse engineering is not limited to mechanical parts or components. Electronic components and computer programs (software) as well as biological, chemical and organic matter can also be reverse engineered

In mechanical engineering, the term reverse engineering (usually abbreviated as RE) is used to summarize the process of reconstructing existing objects. When designing an object from scratch, the engineer will draft the design specifications and generate the drawings used to construct the project. On the contrary, in reverse engineering, design engineers start from the final product and then complete the design process in the opposite direction to arrive at product design specifications. In the process, important information about design concepts and manufacturing methods was discovered.

The Reverse Engineering Process

In order to reverse-engineer physical products, organizations will usually take samples of the products involved and disassemble them to examine their internal mechanisms. In this way, engineers can disclose information about the original design and construction of the product. When performing reverse engineering on mechanical products, the first thing to do is to analyze the size and attributes of the products involved, whether it is airplanes, ships, vehicles, computers or industrial machinery parts. During this analysis, you need to measure the width, length and height of the key components in the product, because these dimensions are usually related to the performance of the product.

Nowadays, some engineers use 3D scanning technology to make such measurements. With the help of a 3D scanner, engineers can accurately read product specifications and automatically record this information in their database. 3D scanning technology includes coordinate measuring machine (CMM), industrial computer tomography (CT) scanner, laser scanner and structured light digitizer.

After collecting and recording all relevant information, you can use this data to create computer-aided design (CAD) drawings for subsequent analysis and development. CAD engineering drawings are two-dimensional and three-dimensional digital representations of products, and you can use them to analyze product designs. These digital models help reveal design intent and provide information for the creation of reverse engineered components.
