Reverse Engineering

With reverse engineering (RE) service, you can digitize your products or parts, modernize your production and product development processes, and eliminate the need for physical inventory. Through 3D scanning, makes it possible to easily and quickly obtain a highly accurate 3D digital model of the assembly and all available components of your part. RE service may be requested due to different demands such as revising the product design, improving the functions of the product in terms of engineering, comparing the competitor’s products with their own product from different angles, or reproducing the product without CAD data. For example, analyzing how a product works, what it does and what components it consists of, estimating costs and identifying potential patent infringement, etc. using for. Value engineering is a related activity that is also used by businesses. It involves deconstructing and analyzing products, but the goal is to find cost-cutting opportunities. Automotive, white goods, defense and aviation sectors are the leading sectors of RE service.

What is
Reverse Engineering?

The process of discovering the technological principles of a device, object or system through the analysis of its structure, function and functioning is called Reverse Engineering. It usually involves taking something apart (for example, a mechanical device, electronic component, or software program) and analyzing its work in detail for use in maintenance, or making a new device or program that does the same without copying anything from the original.

Reverse Engineering – RE

Reverse Engineering

Reverse Engineering (RE) Türkçe’de tersine mühendislik anlamına gelmektedir. Tersine mühendislik, ticari ya da askeri avantaj için donanım analizine dayanmaktadır. Orijinal üretimde yer alan prosedürler hakkında çok az veya hiç ek bilgi olmadan son ürünlerden CAD data elde etmeye reverse engineering denir. Tersine mühendislik yani reverse engineering, işletmeler tarafından mevcut fiziksel geometriyi dijital ürün geliştirme ortamlarına getirmek için de kullanılır.

Reverse Engineering Methods

As computer-aided design (CAD) becomes more popular, reverse engineering; 3D CAD has become a viable method for creating a 3D virtual model of an existing physical part for use in CAM, CAE or other software. The reverse engineering process involves measuring an object and then reconstructing it as a 3D model. Reverse engineering methods may vary depending on the measurement method used. The physical object can be measured using 3D scanning technologies such as CMMs, 3d laser scanning device, 3d optical scanning device or computed tomography. Often represented as a point cloud, the measured data by itself lacks topological information and is therefore often processed and modeled in a more useful format, such as a set of NURBS surfaces or a CAD model.

Reverse Engineering Service

Our reverse engineering service, which creates CAD models of damaged or worn parts by extracting the design intent, has 3 stages.

1. 3D Scanning: A series of 3D scanning technologies are used to capture millions of points that define the geometric features of the object. The raw raster data is called a "Point Cloud" which can be used to get dimensions. This data cloud is used in quality control work or as a guide for building a CAD model.
2. Creating a Mesh Model: The next step is to create a mesh model, unless the project requires the model to be created from the point cloud. A mesh model is created by joining the points forming triangular surfaces. Like a point cloud, the mesh model can be used for inspection or dimensioning. It is the mesh pattern that is normally used as a guide for creating a CAD model. Features such as embossed text and even notches can be removed from the mesh, and underlying geometry can be extracted to be used as a guide to speed up the modeling process.
3. CAD Model Creation: Using the mesh or point cloud as a guide, the CAD model is created. The accuracy of the CAD model is checked against the initial scan data, which provides an accurate representation of the part. At this stage of creating a CAD model from the mesh, any damage or defect that could affect the actual part is removed or the design can be modified according to the customer's demands. If the customer also does not want any changes to the part, the CAD model can also be used as it is created.

Reverse Engineering Applications

Reverse engineering applications are used in different industries to meet different needs. What can RE applications be?
  • Creating a 3D model of a physical part with lost documents
  • If the original manufacturer of a product no longer manufactures the product, it may be necessary to issue 2D / 3D documents of the product.
  • Keeping a digital 3D record of your own products
  • Evaluating competitors’ products, in order to fully reveal the good and bad features of the competitor’s products.
  • In deformation and displacement analysis of worn parts
  • Analyzing the functioning of a product
  • Examine and compare real geometry with a CAD model
