Abstract: Machined mechanical parts made from reinforced polyetheretherketone (PEEK) composite materials have become standard in many high-technology engineering fields. Considering their properties and potential areas of application it is necessary to investigate the machining of reinforced PEEK composite with 30% of carbon fibre (PEEK CF30). In this study, dry turning tests were carried out on PEEK CF 30 specimens using TiN coated cutting tool. An L₂₇ orthogonal array was used for tests. A fuzzy rule-based model is developed to predict the machining force components in turning of carbon fibre-reinforced polymer (CFRP) composites. Good agreement is observed between the predictive model results and the experimental values. The fuzzy rule-based model can be used effectively for predicting the machining force components in turning CFRP composites.
