The grinding process of long fiber reinforced woven composite (LFRWC) is complicated due to the special structure of the material. The force model is beneficial to understand, predict, and even control the machining process. In this study, a new force model considering fiber orientation of LFRWC is developed based on energy balancing theory. Through the construction of a mathematical model, the study demonstrates the correlation of grinding force with the processing parameters and the composite fiber orientation. A semi-analytical force model based on the specific energy is obtained combining with single grain grinding experiment of 3D orthogonal SiO2/SiO2. The influences of grinding parameters on the grinding force are discussed and the major material removal mode is researched. The results show that the predictable model has good consistency with the experimental results, and fiber orientation has a major influence on grinding force. This research on one hand can be used to predict the grinding force of LFRWC, thus conducting the machining and controlling their processing quality; on the other hand, it provides a baseline for selecting the proper machine and tool for LFRWC processing.
