ASTM E2339 Digital Image Correlation for NDT of AM Parts
The ASTM E2339 standard is a cornerstone in the realm of non-destructive testing (NDT) and evaluation within additive manufacturing (AM). This method offers a precise means to assess the structural integrity and surface quality of additively manufactured parts. By leveraging digital image correlation, this technique provides a non-invasive way to measure strain and displacement across the entire part or specific areas without compromising its functionality.
The process begins with careful specimen preparation that ensures accurate and reliable data acquisition. Specimens are typically prepared using common AM materials like stainless steel (316L), aluminum alloys, titanium alloys, and cobalt-chromium-molybdenum (CoCrMo) alloys. The specimens undergo a series of tests to simulate real-world conditions under which they will operate.
Once the specimen is ready, digital image correlation systems capture high-resolution images from multiple angles. These images are then processed using specialized software that calculates displacement and strain values across the entire surface or specific areas identified by the customer. This method allows for detailed analysis of internal stresses and potential defects without the need to physically alter the part.
ASTM E2339 is particularly useful in quality assurance, ensuring parts meet stringent requirements set out by industry standards like ISO 527-1 or ASTM F42. Compliance officers can rely on this testing method to verify that AM parts are free from defects and perform as expected under operational conditions.
For R&D engineers, this technique provides valuable insights into the effects of various manufacturing parameters on part performance. By using ASTM E2339, they can optimize their processes for higher quality outputs while reducing waste and rework costs associated with defective parts.
This testing method is also crucial in the procurement process. When sourcing AM parts from third-party manufacturers, purchasing agents can use ASTM E2339 results to ensure that they are receiving products that meet both internal specifications as well as external regulatory requirements such as EN 15085 or ASME IX.
The accuracy and precision of ASTM E2339 make it an indispensable tool for any organization involved in the development, production, or evaluation of AM parts. Its ability to provide real-time feedback during manufacturing allows for immediate corrections if issues arise, thus enhancing overall product quality.
