TL;DR: In this paper, an analytical method is presented which enables the crater and flank wear of tungsten carbide tools to be predicted for a wide variety of tool shapes and cutting conditions in practical turning operations based on orthogonal cutting data from machining and two wear characteristic constants.

TL;DR: In this paper, the authors proposed an energy-based method to predict chip formation and cutting force for a single point tool of arbitrary geometry, using the predicted results together with an assumption made on the stress distribution on the tool face, the temperature distribution within chip and tool is obtained through a numerical analysis.

TL;DR: In this paper, the residual stress and strain after machining in the workpiece are affected by the flow stress characteristic of the work piece and the cutting conditions, like tool geometry and cutting speed.

TL;DR: In this paper, a process model using the finite element method is proposed and the mechanical effects of the tool's corner radius and feed rate on a machined surface were discussed and the simulated results show quantitative agreement with the residual stress measured experimentally.

TL;DR: In this paper, in situ scratching of silicon with a diamond stylus inside a scanning electron microscope (SEM) using a specially designed tribometer and scratching under zero and high (400 MPa) external hydrostatic pressures was conducted.
