Purpose and goal

The purpose of this project was to perform a preliminary evaluation of the possibilities to couple in-line process measurements using time-resolved digital holography with results from process simulations of an AM-process. Our preliminary results show that such measurements indeed are possible to perform with sufficient precision and that the results from the simulations are on a form suitable for comparison with the measurement outcome. It is further possible to introduce a scaling parameter that compensates for uncertainties introduced in the simulations.

Expected results and effects

We have shown that it is possible to perform these measurements in a realistic manufacturing environment with interferometric precision. As both temporal and spatial information is available from the measurements, the comparison with simulations is relatively straight forward as these outcomes are on a similar form. The results from this project will be presented on the FFI cluster conference in Katrineholm on 24 May and on the conference Speckle2018 in September. In addition a paper is published in connection with the conference. The stipulated effect goals are into the future.

Planned approach and implementation

This project was a collaboration between LTU and GKN, where measurements and analysis were performed at LTU and where process simulations were performed at GKN. The measurements were performed on an available test component made of titanium for which detailed process simulations were available. The measurements were performed in a realistic manufacturing environment. This approach has proven to work satisfactory. However, time for a deeper analysis of the results was lost due to extended measurement time. The primary goals of the project were verified though.

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
