The effect of cutting force model coefficient variability on process planning in milling

, 2011
This thesis describes the effect of force model uncertainty on process planning. Specifically, the statistical variations in model predicted machining forces while cutting aluminum, carbon steel, stainless steel and titanium are determined.

Studies on Veneer Cutting Machine (XX) : Effects of Various Cutting Methods upon Variation of Frictional Coefficient on Knife Rake-Face in Veneer Cutting [PDF]

, 2002
The purpose of this report is to make clear the effects of the inclination angle (i) between the main axis direction of the workpiece and the direction perpendicular to a cutting edge on the cutting surface, the other cutting conditions, and the ...

A combination method of the theory and experiment in determination of cutting force coefficients in ball-end mill processes

, 2015
In this paper, the cutting force calculation of ball-end mill processing was modeled mathematically. All derivations of cutting forces were directly based on the tangential, radial, and axial cutting force components.

Improved dynamic cutting force model with complex coefficients at orthogonal turning [PDF]

, 2019
Self-excited vibration (chatter) is determined by the relation between the vibrating system and the cutting process. In current theories, the dynamic cutting force model in a form suggested by Tlusty and Polacek in the 1950s is still used.

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing

Advanced Engineering Materials, EarlyView.
The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

Investigation of Cutting Force Coefficient Variation in Milling

İmalat Teknolojileri ve Uygulamaları
This study investigates the variation of cutting force coefficients (CFCs) in milling operations and their impact on force predictions and stability analysis. While CFCs are often assumed constant for simplicity, they are inherently dependent on feed per tooth and cutting speed, introducing uncertainties in machining dynamics.

Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys

Advanced Engineering Materials, EarlyView.
Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...
