Finite element analysis and simulation of machining: an addendum: A bibliography (1996–2002)
TL;DR: In this paper, a bibliographical review of the finite element methods applied to the analysis and simulation of welding processes is given, which are classified in the following categories: modelling of welding process in general; modelling of specific welding processes; influence of geometrical parameters; heat transfer and fluid flow in welds; residual stresses and deformations in weld, fracture mechanics and welding; fatigue of welded structures; destructive and non-destructive evaluation of weldments and cracks; welded tubular joints, pipes and pressure vessels/components; welds in plates and other

Effect of lubrication and cutting parameters on ultrasonically assisted turning of Inconel 718
TL;DR: In this paper, the authors further developed the finite element (FE) model of ultrasonically assisted turning discussed in Mitrofanov et al. This model is used to study the effect of cutting parameters (such as the cutting speed, depth of cut and feed rate) and influence of lubrication on various features of two turning techniques, including cutting forces and chip shapes.

3D finite element analysis of ultrasonically assisted turning
TL;DR: Mitrofanov et al. as mentioned in this paper presented a recently developed 3D model of UAT as an extension to their initial 2D model, which allows studying various 3D effects in turning, such as oblique chip formation, as well as to analyse the influence of tool geometry on process parameters, e.g. cutting forces and stresses generated in the workpiece material.

On the temperature distribution in orthogonal machining
G. Arndt,R.H. Brown +1 more
TL;DR: The measurement and calculation of tool temperature distributions in orthogonal machining is reviewed in this article, in which the trial traversing thermocouple probe method previously reported by Balint and Brown [1] was further developed to obtain three-dimensional tool temperature distribution on end-, clearance-and rake-faces and, using a split-chip technique, within the chip-tool interface.

The importance of allowing for the variation of thermal properties in the numerical computation of temperature distribution in machining
TL;DR: In this article, the authors computed the temperature distributions generated during orthogonal machining using the finite element method allowing for variations of thermal properties of the work and tool materials with temperature and found that the effect of such variations from ambient temperature values usually results in a lowering of the shear plane temperature by about 10%.
