This chapter discusses the micromachining processes applied to metallic parts produced through additive manufacturing (AM) technologies. While AM offers significant advantages in producing complex geometries and lightweight components, it often results in challenges related to surface roughness and dimensional accuracy. As such, micromachining serves as a critical postprocessing step to achieve the desired precision and surface quality of AM parts. Techniques such as micromilling, microdrilling, and micro-electrical discharge machining (micro-EDM) are frequently employed for processing AM-produced parts. However, the unique microstructural and mechanical properties of AM metals, as compared to conventionally manufactured parts, introduce various challenges in micromachining. This chapter provides an overview on micromachining methods applied to AM metallic components, addressing issues like surface integrity, and dimensional precision.
