TL;DR: The results indicate that the stress predictions have significant variations with respect to the FE simulation model and these variations can be captured and the resultant surface integrity can be better represented in an interval.

TL;DR: In this article, a finite volume method (FVM) based numerical approach is used and validated against well known experimentally obtained empirical correlations for a misaligned stacked woven wire matrix, the most widely used due to fabrication issues, for Reynolds number up to 400.

TL;DR: In this article, a test bench is designed and manufactured for testing different regenerators under oscillating flow conditions, while three-dimensional numerical simulations are performed to numerically characterize the pressure drop phenomena through a wound woven wire matrix regenerator under different porosity and flow boundary conditions.

TL;DR: In this article, a tool/chip contact temperatures were calculated from the tool side based on analytical theories of heating and the principles of heat generation in cutting processes, and a calibration curve that directly relates real and radiated temperatures was obtained, instead of measuring the emissivity of the radiating surface.

TL;DR: In this article, the influence of tool nose radius in the induced residual stress profile and work-hardened layer when face turning Inconel 718 is analyzed for a cutting speed range between (30-70m/min) and a feed rate range of (015-025mm/rev).
