LAUBSCHER, R.F.; STYSER, G.  and  OOSTHUIZEN, G.A.. A Numerical Analysis of Machining Induced Residual Stresses of Grade 5 Titanium Alloy. R&D j. (Matieland, Online) [online]. 2014, vol.30, pp.39-46. ISSN 2309-8988.

Machining induced residual stresses may have a significant effect on the mechanical performance of machined parts. AdvantEdge is an advanced finite element code dedicated to the modelling of the machining process. This paper describes a comparative evaluation of modelling results obtained with AdvantEdge with experimental results obtained during turning of Grade 5 (Ti6Al4V) titanium alloy. A two dimensional orthogonal turning process is modelled and compared with experimental data. Comparisons are made relative to residual stress, cutting force and cutting temperature for various different cutting parameters including cutting speed, feed rate and cut depth.
