Effect of volcano-like textured coated tools on machining of Ti6Al4V: an experimental and simulative investigation

The present study was to reduce the adhesion and wear that happened on rake face during machining of Ti6Al4V alloys by employing volcano-like textured coated tools. A combination experimental simulative investigation adopted. DEFORM-3D software with updated Lagrangian formulation used for numerical simulation, thermo-mechanical analysis performed using Johnson–Cook material model predict cutting forces, temperature, chip morphology, tool wear. In experiments, textures different area densities (10%, 20%, 30%) were fabricated fiber laser cemented carbide tools close main edge. Then, these deposited CrAlN coating through cathodic vacuum arc ion plating technique. Experiments in carried out non-textured under dry wet conditions. investigated. results showed superior conventional tool. Especially cutting, force radial texture density 20% (VCT2) reduced 11.6% 21.25%, respectively. Surface morphology VCT2 had lower workpiece face. Therefore, a better performance. Finally, mechanisms conditions proposed.
