Precision and accuracy are the main foundation of manufacturing technologies. Regardless of the industry, manufacturing demands uncompromising precision to ensure the reliability and repeatability of production processes.
From intricate components to complex parts, the difference between an excellent product and an unusable component rests in the finest margins. However, traditional methods of metrology services are unable to fulfill this modern manufacturing requirement. But 3D metrology can provide a lasting solution well-suited to today’s manufacturing challenges.
But what is 3D metrology? What are the applications of 3D metrology? Below, we delve into the what, why, and how of 3D metrology as we showcase its applications.
What is 3D Metrology?
3D metrology is the scientific study of precise measurements in three dimensions. It involves obtaining an object’s exact three-dimensional geometrical data along the x, y, and z axes.
In manufacturing terms, it refers to the general field of precision measurement that can be applied in quality control and other applications. Measurements are often acquired through a coordinate measuring machine (CMM), although any form of accurate 3D capture system can be used.
These measurements result in a digital 3D model that can be studied or reverse-engineered. This 3D model is useful in applications like quality inspections, where a 3D scan can be compared to a reference computer-aided design (CAD) model. Through this comparative analysis, you can ensure that the object adheres to established standards.
How Does 3D Metrology Work?
The process of 3D metrology involves several key steps that can be summarized into four key stages:
- Data Collection – 3D metrology begins with data acquisition, wherein detailed measurements of an object’s shape, contours, and features are obtained.
- Data Processing and Analysis – Raw data is fed into data processing software to turn the collected points or images into a coherent and accurate 3D model. This entails stitching the data points and organizing them into a point cloud, which is rendered into a mesh to create a more solid and usable model.
- Comparative Analysis – The obtained 3D model is compared with a reference CAD model to identify deviations. Both models are aligned and matched during this process to identify areas where the actual object’s shape differs from the intended design.
- Visualization and Reporting – After acquiring data from the comparative analysis, a comprehensive report can now be generated summarizing the findings.
What are the Applications of 3D Metrology?
3D metrology finds applications in various industries where accuracy and precision are crucial in developing reliable products. Here are some of the most prominent areas where 3D metrology can be applied:
- Manufacturing and Engineering – Components used by the automotive, aerospace, and electronics industries have minimal tolerances that can be met using 3D metrology.
- Medicine and Healthcare – Manufacturers can utilize 3D metrology to produce medical devices, customized medical implants and other medical components used in patient care.
- Research and Development – 3D metrology enables researchers to create prototypes with accurate dimensions for testing, evaluation and product innovation.
