ISO 12180 Roundness Measurement Testing
The ISO 12180 standard is pivotal in ensuring dimensional accuracy and surface finish quality of parts manufactured through Additive Manufacturing (AM) processes. This service focuses on the precise measurement of roundness, which is a critical parameter for assessing the geometry of AM parts. Roundness is defined as the deviation from a perfect circle or sphere, and it plays a crucial role in determining the functional integrity and performance of components.
Dimensional accuracy is paramount in ensuring that 3D-printed parts meet their design specifications. In Additive Manufacturing, where precision is often challenged by material properties, process parameters, and post-processing methods, ISO 12180 provides a robust framework for evaluating roundness. This standard ensures consistent quality across different AM technologies such as Powder Bed Fusion (PBF), Directed Energy Deposition (DED), and Laser Engineered Net Shaping (LENS).
The testing process involves the use of specialized roundness meters that can measure deviations to within micrometers. These instruments employ optical or mechanical methods to capture data points around the perimeter of a part, allowing for detailed analysis of its geometry. The results are then compared against predefined tolerances specified in ISO 12180, ensuring compliance with industry standards.
For quality managers and R&D engineers involved in AM processes, this service offers critical insights into potential process improvements. By identifying deviations early in the manufacturing cycle, they can adjust parameters to enhance part accuracy. Compliance officers can ensure that their 3D-printed parts meet regulatory requirements, while procurement teams can verify supplier compliance.
