In CFRP orthogonal cutting, the cutting force is strongly dependent on fibre cutting orientation and cutting speed . In grinding, Yan et al. found the grinding force can be significantly affected by grinding wheel mesh and grinding method. Given the complex anisotropic and inhomogeneous structure of CFRP, traditional analytical mechanistic models and numerical simulation models often fail to accurately capture the intricate tool-CFRP interactions and can be computationally intensive. Therefore, data-driven models present a more efficient and adaptable solution for predicting cutting forces in CFRP machining.
