Micromachining of Advanced Materials

Abstract

Market needs often require miniaturized products for portability, size/weight reduction while increasing product capacity. Utilizing additive manufacturing to achieve a complex and functional metallic part has attracted considerable interests in both industry and academia. However, the resulted rough surfaces and low tolerances of as-printed parts require additional steps for microstructure modification, physical and mechanical properties enhancement, and improvement of dimensional/form/surface to meet engineering specifications. Micromachining can (i) produce miniature components or microfeatures on a larger component, and (ii) enhance the quality of additively manufactured metallic components. This chapter suggests the necessary requirements for successful micromachining and cites the research studies on micromachining of metallic materials fabricated by either traditional route or additive technique. Micromachining by nontraditional techniques-e.g., ion/electron beam machining-are beyond the scope of this chapter. The chapter is organized as following:

Micro-machining of additively manufactured metals: a review

“…Components manufactured by AM usually require less machining, since they can be fabricated close to the final shape and dimensions. Therefore, researchers have investigated micromachining of 3D-printed alloys such as Ti-6Al-4 V, 316L stainless steel, Inconel 718, Inconel 625, and H13 tool steel (Hung and Corliss [46]).…”
