-TiAl) alloys can be used in high-end products relevant to the aerospace,
defense, biomedical, and marine industries. Fabricating objects made of 
-TiAl alloys needs an
additive manufacturing process called Electron Beam Melting (EBM) or other similar processes
because these alloys are difficult-to-cut materials. An object fabricated by EBM exhibits poor surface
finish and must undergo postprocessing. In this study, cylindrical specimens were fabricated by
EBM and post-processed by turning at different cutting conditions (cutting speed, depth of cut, feed
rate, insert radius, and coolant flowrate). The EBM conditions were as follows: average powder
size 110 m, acceleration voltage 60 kV, beam current 10 mA, beam scanning speed 2200 mm/s, and
beam focus offset 0.20 mm. The surface roughness and cutting force were recorded for each set of
cutting conditions. The values of the cutting conditions were set by the L36 Design of Experiment
approach. The effects of the cutting conditions on surface roughness and cutting force are elucidated
by constructing the possibility distributions (triangular fuzzy numbers) from the experimental data.
Finally, the optimal cutting conditions to improve the surface finish of specimens made of 
-TiAl
alloys are determined using the possibility distributions. Thus, this study’s outcomes can be used to
develop intelligent systems for optimizing additive manufacturing processes},
