Abrasive belt flap wheel has large elastic deformation, which can better fit the surface of aero-engine blades. Reasonable control of the depth of radial material removal can effectively improve the grinding efficiency and profile accuracy of the blade surface. The depth of radial material removal for flexible grinding was studied through the process parameters in this article. First, the material removal rate model was established based on Hertz elastic contact theory and Preston equation. Then, according to the principle of equivalent material removal volume, a noval approach to determine the depth of radial material removal was proposed. Finally, the experiments for both plane and surface were implemented on a vertical machining center. The results indicate that the proposed method can improve the accuracy and consistency for flexible grinding.

“…Abrasive belt grinding for rail maintenance offers numerous advantages, but it's undeniable that it also poses some challenges, with the most significant being the short lifespan issue caused by the abrasive belt's single-layer grain structure [1]. The lifespan of an abrasive belt is related to its performance and effective grinding area.…”

A comprehensive analysis of an abrasive belt wear monitoring scheme for rail grinding was conducted, focusing on the generation mechanisms of sound and current signals during the sanding process. Initially, we establish a theoretical model linking the sound of belt grinding with its corresponding current generation mechanism. This model also integrates the patterns of abrasive belt wear, laying the groundwork for subsequent signal feature extraction and state recognition. Our approach not only guides the extraction and recognition processes but also ensures the general applicability of our findings, making them more relevant for real-world rail grinding scenarios. The study then delves into an empirical investigation of the characteristics of actual sound and current signals obtained during rail belt grinding. By analyzing these signals across time, frequency, and timefrequency domains, we extract multidimensional signal features. These extracted features serve as crucial inputs for identifying the wear state of the abrasive belt in subsequent chapters. Our methodical approach provides a robust framework for understanding and monitoring the condition of abrasive belts in rail grinding applications, with potential implications for improving efficiency and quality in industrial practices.

Ti6Al4V alloy has been widely used in many fields, such as aerospace and medicine, due to its excellent biocompatibility and mechanical properties. Most high-performance components made of Ti6Al4V alloy usually need to be polished to produce their specific functional requirements. However, due to the material properties of Ti6Al4V, its polishing process still requires significant development. Therefore, this study aimed to investigate the performance of polishing Ti6Al4V by using tools with different rigidities. Two kinds of bonnet tool were used, namely a pure rubber (PR) bonnet and a semirigid (SR) bonnet. The characterization of material removal and surface integrity after polishing was conducted through a series of experiments on a 6-DOF robotic polishing device. The results demonstrate that both bonnet tools successfully produce nanometric level surface roughness. Moreover, the material removal rate of the SR bonnet tool is significantly higher than that of the PR bonnet, which is consistent with the material removal characteristics of glass polishing in previous research. In addition, the presented analysis on key polishing parameters and surface integrity lays the theoretical foundation for the polishing process of titanium alloy in different application fields.
