In this paper, the effects of microgroove textured cutting tools on the residual stress on the machined surface of drying three-dimensional turning of Ti-6AL-4V are investigated using Finite Element Method (FEM). Microgrooves are designed and fabricated on the rake face of cemented carbide (WC/Co) cutting inserts. Specifically, the following microgroove parameters are examined: microgroove width, microgroove depth, and edge distance (the distance from cutting edge to the first microgroove). Their effects are assessed in terms of the circumferential residual stress. It is found that microgroove textured cutting tools can lower the detrimental tensile residual stress and induce beneficial compressive residual stress on the machined surface. The microgroove width, microgroove depth, and edge distance all have influence on residual stress on the machined surface in their own ways. This research provides insightful guidance for optimizing the fatigue life of the components by inducing beneficial compressive residual stress on the machined surface.
