A novel process of chemical-mechanical fluid-solid coupling polishing with high-quality and high-efficiency for turbine blisk
Turbine blisk is the core part of an aero-engine, which is characterized by its complex blade profile, resulting in the difficulty of its polishing. In this study, a novel process of chemical-mechanical fluid-solid coupling polishing was proposed to achieve high-quality and high-efficiency polishing for the blisk. Analyzed the principle of chemical-mechanical fluid-solid coupling polishing process of the blisk with the material of K418 nickel-based alloy. Then, established the material removal theoretical model of the process, and investigated the influence law of process parameters on the blisk surface force state to obtain the optimal parameters by using FLUENT fluid simulation. Moreover, simulated the abrasive particle trajectory to reveal the formation mechanism of the blisk surface with high-quality and high-efficiency. Furtherly, experiment shows that the novel process can effectively improve the blisk surface quality, and the surface roughness Ra decreased from 3.151 μm to 0.779 μm. This method provides a novel solution for precision polishing of the complex structural parts.
期刊介绍:
The aim of the Journal of Manufacturing Processes (JMP) is to exchange current and future directions of manufacturing processes research, development and implementation, and to publish archival scholarly literature with a view to advancing state-of-the-art manufacturing processes and encouraging innovation for developing new and efficient processes. The journal will also publish from other research communities for rapid communication of innovative new concepts. Special-topic issues on emerging technologies and invited papers will also be published.
