Modelling the Effects of Flank Wear Land and Chip Formation on Residual Stresses

摘要: Abstract The selection of optimum machining parameters and tool geometry for difficult to cut materials used in aerospace applications is usually controlled by the quality integrity surface produced, burr formation part distortion. In this paper, a finite element model developed simulate effects flank wear chip on residual stress when orthogonal cutting Ti-6AI-4V. A crack propagation module also incorporated into solver accurately segmental chips produced during titanium. predicted results emphasize importance modelling mechanism correctly because their effect forces temperature field. This subsequently influences magnitude distributions stress. Good correlation was obtained between measured distribution.
