TL;DR: In this article, a new parameter based on acoustic emission (AE) signal energy (frequency range between 100 and 300 kHz) was introduced to improve response of tool wear in end milling.

TL;DR: In this paper, the authors evaluate different cemented carbide grades, cutting speeds, and feed per tooth rates, aiming to determine the best condition for face milling of nickel-based 625 superalloy.

TL;DR: In this article, the authors evaluated the impact of the path's influence on the cutting forces and surface roughness, and simultaneously the impact on milling parameters (cutting speed, feed, and path period).

TL;DR: In this paper, an ultrasonic-assisted turning (UAT) of advanced ceramics in a green state where a flexure hinge was developed for allowing tool vibration only toward the depth of cut direction was investigated, which provided process benefits through improved surface finish due to reduced lump pull-outs, decreased tool flank wear by 34%, and reduced machining forces.

TL;DR: In this paper, the authors evaluated the tool nose radius effects at the machining forces and surface roughness during the turning of green ceramic parts, and they found that the 0.05-mm nose radius introduced severe damages on the compact surface, which favors the pulling out of the green compact agglomerates.
