TL;DR: In this article, the tensile behavior and microhardness of 316L stainless steel fabricated by selective laser melting under different process parameters were investigated, and the results indicate that selective laser welding may act as a physical metallurgy method to modify the microstructure, and thus improve the mechanical performance of metallic materials.

TL;DR: In this article, the authors introduced the signal processing methods such as time domain, frequency domain, and time-frequency domain analysis to identify the chatter and select suitable cutting parameters to avoid chatter at high material removal rate (MRR).

TL;DR: A cutting condition independent TCM approach for milling with vibration singularity analysis is introduced which utilized a Support Vector Machine model and a transition point identification method (TPIM).

TL;DR: In this paper, three drill geometries, multipoint, step and double cone, were designed and experimentally evaluated to understand the effect of tool geometry on the machining performance of dry drilling Al/Ti stack.

TL;DR: In this paper, a systematic investigation on the process parameters for achieving high tensile strength and ductility of manufactured Ti-based alloys by selective laser melting (SLM) while still maintaining the high mechanical strength is performed.
