Summary: A novel one-step reverse compensation method based on a variable shrinkage factor is proposed to control the deformation of hollow turbine blades during investment casting. The directional solidification process is simulated to predict the deformation distribution, and the shrinkage rate of each finite element node is calculated to guide mold design. Experimental results show that the optimized deformation using this method is within the design requirement and the maximum deformation of the blade is significantly reduced.

Summary: With the continuous improvement of thrust-to-weight ratio and endurance in advanced aero-engines, higher requirements are being imposed on blade surface quality. Robot abrasive belt grinding offers excellent flexibility, convenient scheduling, strong adaptability, and low cost advantages. However, factors such as low repeated positioning accuracy, weak structural stiffness, and elastic deformation during belt grinding significantly influence the surface quality and contour accuracy of robot belt grinding.

Summary: Robotic grinding is a promising method for forming industrial component surfaces, improving quality, lowering costs, and reducing processing time. The efficiency of grinding depends on surface matching between measured points and design models, with existing methods often leading to high processing time and unstable quality. The novel surface matching method proposed in this article balances all measured points' contributions and is effective in reducing grinding time.

Summary: In this article, a mobile robotic grinding system for large-scale workpiece is proposed. The mobile robot is equipped with a laser sensor, fringe projection scanner, and force-controlled grinding tool. The mobile robot can move in large spaces, calibrate the workpiece accurately, and perform grinding work automatically. A vision-based grinding strategy for the mobile robot is proposed, where the workpiece surface reconstruction and grinding path planning are generated by the measured point clouts. An error index is proposed to analyze the machining accuracy, which can reveal the primary error factor in the error transfer chain. Compared with the mobile robotic grinding based on the global measurement system in (Zhao et al., 2021), the proposed vision-based grinding process requires no precise CAD model of the workpiece and achieves better machining accuracy. Two experiments are conducted in this article, where a wind turbine blade and a part of the aircraft skin have been ground by the mobile robot. Experiments show that the mobile robot under the vision-based grinding strategy is suited for different continuous surfaces, and it has great application prospects.
