How Persuasive Are Three-Dimensional Scanners?

The term “quality control” refers to the steps taken throughout production to guarantee that products meet specified standards. To verify whether a component is in accordance with the guidelines and requirements, like CAD models, it is common practice to measure, examine, test, or inspect its many qualities. Having a quality control checkpoint in place throughout production is crucial for ensuring that products are consistently of a high level and for ensuring that manufacturing facilities continue to meet those requirements. Better quality items are delivered to customers as a result of quality control measures. Increases in quality lead to greater satisfaction and retention, which in turn helps to fortify pre-existing demands while also giving birth to new ones. There are a variety of quality control measuring tools available to tape and reel Malaysia manufacturers. CMMs might be favored since they are the most precise metrology equipment for quality inspection. There are drawbacks to achieving such precision, though. In spite of their versatility, CMMs are often overworked due to the fact that they’re not the quickest metrology instrument in terms of setting and operation timeframes. As a result, 3D scanning is a useful alternative to the CMM and one of the finest techniques for quality control.

The meaning of 3D scanning

Scanning in three dimensions (or “3D scanning”) is a method of studying real-world environments and objects by gathering information on their form, geometry, and texture. After data collection, 3D digital models may be created.

A 3D model is built using a point cloud, which is a collection of geometric surface samples taken from the item in question. By extrapolating from these locations, we may rebuild the actual object’s form, geometry, and texture. In order to get the data required to create 3D models, 3D scanners are used.

What Are the Various Kinds of 3D Scanners Used in Metrology?

To digitally capture an object’s form, geometry, and texture, two primary categories of 3D scanners exist: contact and non-contact. Contact 3D scanners measure an object’s three-dimensional shape by touching it while it is perched on a perfectly flat surface or held in place by a fastening. Contact 3D scanners include conventional coordinate measuring machines (CMMs), movable measuring arms, and manually operated touch probes. In order to gather information about an object’s shape, geometry, and texture, non-contact 3D scanners often use laser lines or white light and cameras to read the object’s reflection. The laser mirror, the sensor, and the laser source all work together to produce a triangle, thus the name “triangulation.” Non-contact 3D scanners include, but are not limited to, laser-based scanners, scanners using structured light (or white light), and optical CMM scanners. Photogrammetry is another non-invasive technique for determining an object’s 3D form from photographs alone.

Which 3D Scanners Are Best for Quality Control and Metrology?

When assessing quality, precision is of the utmost importance. Inspecting features with a tight tolerance should be left to conventional CMMs, while 3D scanners should be used for all these other quality assurance tasks, especially those performed on the factory floor. They preserve valuable CMM time for more important inspections while also measuring more quickly, requiring less time for training, handling, and programming.

Additionally, 3D scanners can alleviate bottleneck concerns and lessen the burden of conventional CMMs. The whole suite of handheld 3D optical measuring technologies developed by Micro Modular 3D Measurement and 3D Inspections Malaysia system is tailored to facilitate dimensional examination for quality management in a manufacturing setting. They are able to check the conformance and quality of produced items whatever their size, form, material, surface polish, or complexity because to their exceptional precision, speed, mobility, and adaptability.
