Two-loop five-point all-plus helicity Yang-Mills amplitude [PDF]

open access: yesPhysical Review D, 2016
We re-compute the recently derived two-loop five-point all plus Yang-Mills amplitude using Unitarity and Recursion. Recursion requires augmented recursion to determine the sub-leading pole. Using these methods the simplicity of this amplitude is understood.

Performance assessment and optimization of Ti6Al4V helical hole milling process

open access: yesMaterials Research Express
The superior metallurgical properties exhibited by Ti6Al4V alloy make hole drilling a tedious task. Therefore, the helical milling process was analyzed as an alternative for machining Ti6Al4V alloy in the present work. Using Analysis of Variance (ANOVA),

Investigating the Performance of Coated Carbide Insert in Hard Steel Helical Milling [PDF]

open access: yesInternational Journal of Advanced Design and Manufacturing Technology, 2018
Helical milling is an alternative hole-making machining process which presents several advantages when compared to conventional drilling. In the helical milling process, the tool proceeds a helical path while rotates around its own axis.

Tool-path effect on the geometric deviations in the machining of UNS A92024 aeronautic skins [PDF]

open access: yes, 2017
Traditionally, aeronautics skins are being machined by chemical milling, a high-pollutant process. An efficient alternative to this technology is conventional machining. However, to ensure the parts machined with this process keeps the industrial quality

Application of the stability lobes theory to milling of thin workpieces, experimental approach [PDF]

open access: yes, 2003
The optimisation of cutting conditions in High Speed Machining (HSM) requires the use of a vibratory approach in order to avoid a fast deterioration of the tool and of the spindle, as well as a loss of quality of the surface rough- ness.
