File name structure: Structure: Provide the template you are using for your filenames: Files are stored in zipped folders according to the type of measurement/ simulation Attributes: Describe the attributes used to name the files: High-Precision_Machining_BGO-3D_microscope_data: 0-x feed: where x=2 or 4, describes the diameter of the mill used to produce the measured channels (i.e., 0.2 and 0.4 mm). The suffix 3d means that the image/data are 3D data. High-Precision_Machining_BGO-CCI-and-roughness: data are stored in two subfolders: 0-2 mm diameter, 0-4 mm diameter, according to the diameter of the mill used to produce the channels (i.e., 0.2 and 0.4 mm diameter). CCI data and workbooks: BGO 0-x mm diameter mill yyymm min-1 where 0-x is the diameter of the mill (i.e., 0.2 or 0.4 mm) and yyy is the feedrate in mm min-1 (i.e., 10 or 100 mm min-1). Extracted roughness and waviness data are stored as:m_0-x_yyy_z where 0-x is the diameter of the mill (i.e., 0.2 or 0.4 mm) and yyy is the feedrate in mm min-1 (i.e., 10 or 100 mm min-1), r = roughness profile and w = waviness. Images of these profiles are stored as m0-x_yyy where 0-x is the diameter of the mill (i.e., 0.2 or 0.4 mm) and yyy is the feedrate in mm min-1 (i.e., 10 or 100 mm min-1). High-Precision_Machining_BGO-SEM_images: data are stored in the format 0-x-yy-zz, where 0-x is the diameter of the mill (i.e., 0.2 or 0.4 mm) and yyy is the feedrate in mm min-1 (i.e., 10 or 100 mm min-1), z is the field of view of the microscope, 50 = 50 um, overview = 500 um. High-Precision_Machining_BGO-compression_test: data are stored in two subfolders: compression_test_data and compression_test_images: Quasi-static Raw Data- raw unprocessed data for the quasi-static compression tests, QS- Experimental tests (C1-C5) - processed quasi-static compression test data, QS- Mean Values of Experimental tests (C1-C5)- average of the quasi-static compression test data from QS- Experimental tests (C1-C5), Split Raw Data- raw unprocessed data from the split tests, Split- Experimental tests (S1-S3)- processed split test data, Split- Mean Values of Experimental tests S1-S3 - average of the split test data from Split- Experimental tests (S1-S3), image files are named according to their figure name in the related article. High-Precision_Machining_BGO-Simulation: data are stored in two subfolders: Compression- data relating to simulation of the compression testing, and Milling- data relating to simulations of the milling process: Compression: QS- Simulation Values- input data for the simulation of the quasi-static compression tests, Split- Simulation Values - input data for the simulation of the split tests. Image files are labelled according to their figure number in the related article.
