VIBRATION-ASSISTED TURNING SIMULATION WITH TEXTURED TOOLS: A NUMERICAL INVESTIGATION

Abstract

In this study, through numerical simulation, an effort has been made to acknowledge the efficiency of machining Titanium grade 23 under vibration assistance with textured cutting tools. Dry turning experiments with commercially available carbide inserts without texturing were carried out without vibration assistance. Cutting forces ([Formula: see text][Formula: see text], [Formula: see text][Formula: see text], [Formula: see text][Formula: see text]) were observed during experimentation, which were further validated using DEFORM 3D. The forces were validated using DEFORM 3D. Closer to the cutting edge, dimple type 1, dimple type 2, horizontal, and vertical patterns were made on cutting inserts using SOLIDWORKS software. A numerical model based on experimentation was developed employing DEFORM 3D software for conventional and vibration-assisted turning. Cutting forces ([Formula: see text][Formula: see text], [Formula: see text][Formula: see text], [Formula: see text][Formula: see text]), cutting temperature, tool wear, and the mechanism of chip formation were also explored through FEM investigation. Micro-textured inserts were found to be enhancing machinability. Machining with vibration assistance also improved machinability. The study found that textured tools improved machinability in conventional and vibration-assisted machining modes. The effect of textured tools on machinability improved with vibration-assisted machining. The numerical analysis revealed that dimple type 1 and vertical grooved tool improved the machinability of Titanium grade 23.
