<p>To address the issues of excessive cutting temperature and rapid tool wear during the machining of nickel-based superalloys, this paper employed laser processing to create three distinct types of textures on the rake face of carbide cutting tool: circular pit textures (T-D), grooved textures perpendicular to the cutting edge (T-V), and grooved textures parallel to the cutting edge (T-P).

摘要

To address the issues of excessive cutting temperature and rapid tool wear during the machining of nickel-based superalloys, this paper employed laser processing to create three distinct types of textures on the rake face of carbide cutting tool: circular pit textures (T-D), grooved textures perpendicular to the cutting edge (T-V), and grooved textures parallel to the cutting edge (T-P). The study experimentally investigated the cutting performance when machining nickel-based superalloy using a combination of mixed nanofluid cutting fluid minimum quantity lubrication (MQL) and different textured cutting tools. The results indicate that under dry cutting conditions, the surface texture has little to no impact on the cutting force. Conversely, under mixed nanofluid cutting fluid MQL conditions, the surface texture on the rake face of the cutting tool helps reduce the friction between the chip and the tool, and improves convective heat transfer between the rake face and the surrounding air. This in turn lowers both cutting force and temperature, while also extending tool life. In addition, the morphology of the texture plays a crucial role in affecting cutting property. Among the three textured tools, the cutting tool T-V exhibits the best performance. In comparison to the untextured tool, the cutting tool T-V achieves 6.9 to 9.2% reduction in cutting force, lowers the maximum cutting temperature by 7.1% on average, and increases tool life by 44%. The experimental results of this study demonstrate that a well-designed surface texture morphology, in conjunction with mixed nanofluid cutting fluid MQL conditions, is a feasible machining technique for nickel-based superalloy processing.
