3 Important Steps to Reverse Engineering a Part

Over the past 120 years, there has been a production of millions of machine parts and products worldwide. However, few of these products are still relevant over the years because of the technological advancement, but lots of old parts used in machines are still in use. When a part breaks down or malfunctions, it is usually replaced using a process known as reverse engineering.

There are many things that can be learned from a machine or software, just from reverse engineering. This is because the concept behind the reverse engineering process is to break something down to help understand it, and the engineer can then build a copy or try to improve it. Furthermore, there is a need for a reverse engineering design process as the technology advances to ensure the existing manufacturing systems’ continuity.

Reverse engineering is an important process for everybody as we will be forced to replace entire machines without it. In this article, we will break down everything you need to know about reverse engineering, from reverse engineering to reverse engineering processes.

What is reverse engineering?

Reverse engineering, also known as back engineering, is the process where machines, software, architectural structures, and other products are deconstructed to gather design information from them. Furthermore, most companies use this method when buying a replacement part from an original equipment manufacturer.

This shows reverse engineering methods involve working backward through an original design process to gain a working knowledge of a product’s original design.

What Is Reverse Engineering Used For?

Reverse engineering in software and machines aids the duplication of an existing part by gathering the features, physical dimensions, and material properties of a component. Some of the uses of reverse engineering are stated below.

Legacy Components

Lots of components designed and manufactured years ago do not have existing 2D drawings or 3D CAD data that can be used to reproduce the object. However, with reverse engineering, manufacturers can gather the necessary information needed to recreate the product.

Original Equipment Manufacturer (OEM) Issues

There are situations where the original equipment manufacturer is no longer trading or has lost its design measurements. Manufacturers can now use reverse engineering steps to get vital product information to continue manufacturing the object.

For Design Development, Part Testing & Analysis

With the help of reverse engineering, the 3D product can be easily captured in digital form, and it can then be analyzed or remodeled to produce a much more improved design.

For Competitor Analysis

An organization can use reverse engineering to analyze competitor products.

Some of the other uses of reverse engineering methods are producing bespoke and ancient objects, digital archiving, modern manufacturing, etc.

Steps Involved in Reverse Engineering A Part

3 Steps of Reverse Engineering

In reverse engineering, once you have an idea that you want to build the models, you can then produce it using the CAD (Computer-Aided Design) models. To do this, you will need a finished part to scan to build a CAD model and then refine the model. Some of the steps involved are stated below.

Step 1: Capture Data

The first step is to capture the data from the existing part. You can use varieties of scanning equipment for this based on the material and the size of the part. The scanner will then produce 3D scan data output like a dense triangle mesh. This data will be used as a visual sketch, and you will need to do a little manipulation before getting the final CAD file.

Some of the software reverse engineering used for capturing data is mobile Faro arms, Faro laser scanner, etc.

Step 2: Refine the Model

After you have the detailed dimensions of the scan files, you can then refine them into a final part. However, this process can differ based on the software for reverse engineering used. Refining the model involves using automated technology inside the software with human manipulation to aid the completion of the CAD model.

The point cloud or mesh form received from the scanner will now be turned into a polygonal model. After that, you will clean up, smooth, and sculpt the resulting mesh to retain its needed shape and accuracy.

Step 3: Manufacturing

Once the CAD model is complete, you can then manufacture the part. Based on the part size and its application, you may want to do a 3D print of the CAD model to compare it with the original part before it is mass-produced.

Learn Reverse Engineering from the Pros

Reverse engineering is the process of understanding machine code and being able to modify it. With EC-Council’s CodeRed course (coming soon), you will learn how to be an expert reverse engineer. You will learn all the methods you can use to increase your performance as a reverse engineer. You will also know about the various tools for the reverse engineer and how to use them.

Furthermore, you will be taught how to protect against reverse engineering and ways of bypassing those protections. By the end of this course, you will be able to trace, understand and modify binary files to get your desired effect. Furthermore, you will learn how to discover possible security flaws in an application.

Is it illegal to reverse engineer?
It is lawful for an engineer to reverse-engineer an artifact or process if you obtain it legitimately. However, you don’t necessarily need to reverse-engineer a patented software because the patents require public disclosure of an invention.
