Abstract

Coupling additive manufacturing with milling changes the interaction between the cutting tool and workpiece. The resulting effect on tool wear and surface integrity is poorly understood. Maraging steel printed via powder bed fusion was peripherally milled in the presence of un-melted metallic powder surrounding the printed part. Areal surface parameters, microhardness, and tool wear were analyzed. Results showed that milling within powder decreased surface roughness and introduced a weak orthogonal texture between the feed marks and printed layers. Milling without powder caused a more pronounced inclined texture. Milling within powder accelerated flank wear while milling without powder accelerated crater wear.
