Abstract The application of Carbon Fiber Reinforced ThermoPlastic matrix composites (CFRTP) is constantly increasing today. They have an excellent weight-to-mechanical properties ratio and in comparison to thermostable matrix composites their recycling efficiency is higher. However, these must be machined to obtain complex geometries that perform their function. The abrasive water jet machining (AWJM) is a process free of thermal defects, avoiding to reach the glass transition temperatures of the thermoplastic matrix. At the same time, it can generate very good surface quality results. This article focuses on the influence of cutting parameters on the AWJM machining of a CFRTP through surface quality. The surface quality has been evaluated in three different regions of the thickness generated. Finally, some contour diagrams obtained allow to predict the surface quality with in the cutting parameters used.
