Analysis of the influence of geometric parameters of laser-produced texturing on carbide tools in Ti6Al4V turning

Abstract

This study focuses on analyzing the influence of different groove texture geometries on carbide cutting tools for turning Ti6Al4V titanium alloy, exploring how different parameters (depth, width, spacing, direction, and distance from the cutting edge) affect machining performance. This work contributes to the advancement of machining techniques, promoting more efficient and sustainable processes, with potential practical applications in industry. The objectives include reducing machining forces while minimizing machining costs. The methodology employed advanced technologies, such as femtosecond lasers, to produce defect-free textures without thermal damage or microcracks. Initial results demonstrated that textured tools can significantly improve the machining process by reducing machining forces. The results showed that texture direction and distance from the cutting edge were the most influential parameters, while texture dimensions had a lesser impact. Furthermore, the effects of textures were found to vary with feed rate, highlighting the need for specific optimizations for different cutting regimes (such as roughing or finishing).
