Fabricating objects made of \n-TiAl alloys needs an\nadditive manufacturing process called Electron Beam Melting (EBM) or other similar processes\nbecause these alloys are difficult-to-cut materials. An object fabricated by EBM exhibits poor surface\nfinish and must undergo postprocessing. In this study, cylindrical specimens were fabricated by\nEBM and post-processed by turning at different cutting conditions (cutting speed, depth of cut, feed\nrate, insert radius, and coolant flowrate). The EBM conditions were as follows: average powder\nsize 110 m, acceleration voltage 60 kV, beam current 10 mA, beam scanning speed 2200 mm/s, and\nbeam focus offset 0.20 mm. The surface roughness and cutting force were recorded for each set of\ncutting conditions. The values of the cutting conditions were set by the L36 Design of Experiment\napproach. The effects of the cutting conditions on surface roughness and cutting force are elucidated\nby constructing the possibility distributions (triangular fuzzy numbers) from the experimental data.\nFinally, the optimal cutting conditions to improve the surface finish of specimens made of \n-TiAl\nalloys are determined using the possibility distributions. Thus, this study’s outcomes can be used to\ndevelop intelligent systems for optimizing additive manufacturing processes","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_3_full_name_242":{"attribute_name":"著者（英）","attribute_value_mlt":[{"names":[{"name":"M.
