Comparison of machining performance of stainless steel 316L produced by selective laser melting and electron beam melting
Paper in proceeding, 2022

Powder bed fusion based additively manufactured SS 316L components fall short of surface integrity requirements needed for optimal functional performance. Hence, machining is required to achieve dimensional accuracy and to enhance surface integrity charcteristics. This research is focused on comparing the material removal performance of 316L produced by PBF-LB (laser) and PBF-EB (electron beam) in terms of tool wear and surface integrity. The results showed comparable surface topography and residual stress profiles. While the hardness profiles revealed work hardening at the surface where PBF-LB specimens being more susceptible to work hardening. The investigation also revealed differences in the grogress of the tool wear when machining specimens with either PBF-LB or PBF-EB.
