An exact tool allocation approach for CNC machines [PDF]

International Journal of Computer Integrated Manufacturing, 1999
An exact approach is developed to determine the optimum machining conditions and tool allocation decisions simultaneouslyto minimize the total production coston a CNC turning machine. There are multiple machining operations and we consider a set of alternative cutting tool types for each operation.

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated
