Abstract Scope |
The aerospace industry recognizes the benefits of AM not just in terms of complexity but also with regard to producing replacement parts for an aging fleet of aircraft. However, the quality must be well established given the lack of heritage for this manufacturing process. As additive manufacturing is executed layerwise, opportunities exist to non-destructively verify the fabrication in situ with a qualify-as-you-go methodology. A proposed solution is presented, which utilizes a pair of low cost, high speed cameras are integrated and synchronized together to provide stereovision in order to identify the size, speed, direction and age of spatter ejected from the laser melt pool. The driving hypothesis of the effort is that the behavior of spatter can be reliably measured in order to determine the health of the laser process and ensure that spatter is not contaminating the build. Results are shown for AlSi10Mg spatter generated under various process parameters. |
