Influence of Micro-Textures on Cutting Insert Heat Dissipation

Metal machining is one of the most important manufacturing processes in today’s production sector. The tools used have been developed over years to improve their performance, by reducing cutting forces, friction coefficient, and heat generated during process. Several cooling systems emerged as an effective way remove excessive from chip-tool contact region. In recent years, introduction nano micro-textures on surface has allowed further overall performance. However, there not sufficient scientific data clearly show how texturing can contribute reduction tool temperature identify its mechanisms. Therefore, this work proposes experimental setup study characteristics’ impact transfer rate tools’ fluid. Firstly, a numerical model mimic energy flow tool. Next, design variables were adjusted get linear system response achieve fast steady-state thermal condition. Finally, device was implemented based optimized model. A good agreement obtained between tests simulations, validating concept implementation setup. square grid pattern 100 μm × with grooves depths 50, 100, 150 introduced insert surfaces laser ablation. results that increase depth relatively standard surface, 3.77% for μm. This associated area coolant, generation greater fluid turbulence near enhancement wettability.
