dc.description.abstractThis data set supports a study on the machinability of a single crystal scintillator, Bismuth Germanate (BGO), a material widely used in Time-of-Flight Positron Emission Tomography (TOF-PET). In this study, the Johnson-Holmquist 2 (JH-2) material model was used to simulate the micro-milling process for BGO. Key parameters for the JH-2 model were estimated from experimental data from quasi-static compression and split tests. Simulations performed using different machining parameters were compared with equivalent machined samples and were able to successfully replicate the conditions observed. This dataset compiles the data and meshes used during the simulations, the compression and split test data, microscopy data for the machined sample, and white light interferometry data used to calculate machined surface roughness and the post-processing required to extract the roughness values.
