TL;DR: An overview of the recent advances in high performance cutting of aerospace alloys and composite currently used in aeroengine and aerostructure applications is presented in this paper, focusing on the role of hybrid machining processes and cooling strategies (MQL, high pressure coolant, cryogenic) on machining performance.

TL;DR: An overview of major cryogenic manufacturing processes, summarizing the state-of-the-art and significant developments during the last few decades, is presented in this article, with a summary of historic perspectives, including definitions, scope, and analysis of process mechanics and material performance covering tribological and thermo-mechanical interactions.

TL;DR: In this article, the wear mechanisms of tungsten carbide (WC) drills during dry high speed drilling of quasi-isotropic woven graphite fiber epoxy composites were investigated.

TL;DR: In this article, the results of an experimental investigation on the wear mechanisms of uncoated tungsten carbide (WC) and coated tools (single layer (TiAlN) PVD, and triple-layer (TiCN/Al 2 O 3 /TiN) CVD) were presented.

TL;DR: Phenomenological and physically-based constitutive models commonly used in machining simulations are presented and discussed and thermo-physical properties for thermal modelling of the machining process, and microstructure data for the chip and workpiece together with relevant experimental methods are discussed.
