Abstract: Cutting forces affect machining quality and part integrity. Delamination is directly related to the cutting forces, and hence predicting and controlling the cutting forces would lead to controlling and preventing delamination. This work utilises the mechanistic modelling approach for predicting cutting forces in the milling process of carbon fibre reinforced composites. Specific energy functions were determined by regression analysis of experimental data and a cutting model was developed. It is shown that the model is capable of predicting cutting forces in milling of both unidirectional and multidirectional laminates. Model predictions were found to be in good agreement with experimental results.
