Abstract

As metal AM technologies have realized significant development, hybrid manufacturing, which integrates both additive and subtractive processes in a single machine tool, has emerged in order to tackle the geometrical and surface defects that are present in AM parts. Due to their unique microstructure, subtractive process planning has to be re-evaluated. This work aims at investigating the machinability of AM-produced components in the scope of hybrid manufacturing. A preliminary experimental investigation of surface quality and tool wear has been made using BOHLER K890 samples manufactured by utilizing DED process. Core milling parameters have been evaluated regarding their effect on the final result.
