AI Technical Summary
Existing thermal error compensation technologies for five-axis linkage gantry machining centers suffer from problems such as lag, insufficient sensor accuracy, poor data transmission delay and synchronization, poor model adaptability and robustness, insufficient independence of tool thermal deformation compensation, and low system integration, making it difficult to meet the high precision requirements of modern precision manufacturing.
By employing a fiber optic bus communication network, distributed FBG temperature field monitoring, laser tracker calibration, and CNN-LSTM error prediction model, combined with an integrated compensation architecture, real-time error compensation for multi-physics coupling is achieved. Through the collaborative optimization of synchronous communication module, temperature field sensing module, calibration and verification module, operation status monitoring module, modeling and prediction module, and compensation execution module, a closed-loop control architecture is constructed to achieve high-precision and real-time adaptive compensation for thermal dynamic errors.
It enables real-time monitoring and compensation of machine tool thermal deformation, improves machining accuracy and production efficiency, reduces system maintenance difficulty, adapts to machine tool aging and environmental changes, and ensures high precision and stability of five-axis linkage machining.
