- CAD file dataset of the ISAAC AM petal re-design project(2023) Westsik, Marcell; Wells, James T.; Chahid, Younes; Morris, Katherine; Milanova, Maria; Beardsley, Mat; Harris, Michael; Ward, Lucas; Alcock, Simon G.; Nistea, Ioana-Theodora; Atkins, CarolynThis dataset contains the .STL files of the Graph and TPMS Additively Manufactured petals. For both designs, an "As Printed" and an "As Postprocessed" version is included. These designs are detailed in the paper submitted to SPIE titled "From design to evaluation of an additively manufactured, lightweight, deployable mirror for Earth observation".
- CAD files from "Lightweighting large optomechanical structures in astronomy instrumentation utilising generative design and additive manufacturing"(2023-07-06) Atkins, Carolyn; Wells, James T.; Westsik, Marcell; Chahid, Younes; Mcleod, Alastair; Bissell, Lawrence; Kotlewski, Richard; McPhee, Scott; Orr, Jonathan; Pimentel, Misael; Cochrane, William; Breen, CiaránFiles contain .step files for the topology-optimised design and the varied wall thickness design. These designs are detailed in the paper submitted to SPIE Optomechanical Engineering 2023 titled "Lightweighting large optomechanical structures in astronomy instrumentation utilising generative design and additive manufacturing"
- Multi Threshold Comparator Avizo Plugin(2022-12) Chahid, Younes; Packer, Chris; Tawfik, Ahmed; Keen, Joel; Beardsley, Mat; Morris, Katherine; Bills, Paul; Blunt, Liam; Atkins, Carolyn; Tammas-Williams, SPart 1/2: The Multi Threshold Comparator is an Avizo software plugin that assist users in choosing the threshold value when using X-ray Computed Tomography data for porosity analysis. The objective of the developed Avizo plugin is to compare multiple threshold types (Otsu, global and local) across a range of values, based on a previously measured hole, to eventually assist the user in choosing the suitable threshold value. The plugin .zip file is composed of the .pyscro and .rc files to be placed in Avizo installation folder. The hole data to be analysed needs to have a minimum of 2 slice images, and the orientation of the stack needs to show the diameter as circles. Further information can be found in the readme file and detailed use of the plugin is in the study titled "Development of a modular system to provide confidence in porosity analysis of additively manufactured components using X-ray computed tomography". Part 2/2: This second half of the dataset is composed of sample data used in the study and their outputs which can be found in DOI: http://dx.doi.org/10.5286/edata/901
- Outgassing Measurements for "Lightweighting large optomechanical structures in astronomy instrumentation utilising generative design and additive manufacturing"(2023-09-19) Wells, James; Westsik, Marcell; Chahid, Younes; Macleod, Alastair; Kotlewski, Richard; McPhee, Scott; Orr, Jonathan; Pimentel Espirindio e Silva, Misael; McKegney, Scott; Cochrane, William; Breen, CiaránDataset contains raw text files from outgassing measurements of Wire-Arc Additive Manufactured (WAAM) samples presented in the conference paper "Lightweighting large optomechanical structures in astronomy instrumentation utilising generative design and additive manufacturing" (SPIE Optomechanical Engineering 2023) Files contain the pressure and temperature measurements used to calculate outgassing rates for the WAAM samples. For details of the analysis see the paper and the associated GitHub repository. README contains information on raw file format.
