Abstract: A Finite element modeling was developed for the computational machining of titanium alloy Ti-6Al-4V. The chip formation in metal cutting is one of the large deformation problems, thus, in the ...

Abstract: Direct measurements of the distributions of normal and frictional stresses on a rake face under cutting conditions have been considered to be practically impossible. However, as reported in this ...

Abstract: The cutting model and the energy method to predict chip formation and cutting force, which were proposed in the previous part of this study, are extended to machining with conventional ...

Abstract: Tools which provide controlled contact on the tool face are used to study the action of free machining steels. The mean normal stress on the tool face σc is found to increase with increased ...

Abstract: Fracture onset coefficients and edge shape transition probabilities made it possible to evaluate the edge fracture characteristics of abrasive grain rationally. By grinding tests of single grain, ...

Abstract: Cut-away tools have a strong tendency to produce a complicated plastic flow ahead of the restricted tool-chip contact area as far as the restriction is in effect. The paper stresses the ...

Abstract: Through the energy method proposed in the previous parts of this study, it is possible to predict chip formation and cutting force for a single point tool of arbitrary geometry. By using the ...

Abstract: The paper proposes a new model of chip forming process in three dimensional cutting with single point tool, in which the process is interpreted as a piling up of orthogonal cuttings along ...

Abstract: Tests upon a variety of friction sliders reveal that, contrary to common belief, manganese sulfide is a poor solid lubricant relative to air. Lead, on the other hand, is found to be an ...
