AB The use of composite materials with a polymeric matrix, concretely carbon fiber reinforcedpolymer, is undergoing further development owing to the maturity reached by the forming processesand their excellent relationship in terms of specific properties. This means that they can beimplemented more easily in di erent industrial sectors at a lower cost. However, when thecomponents manufactured demand high dimensional and geometric requirements, they must besubjected to machining processes that cause damage to the material. As a result, alternative methodsto conventional machining are increasingly being proposed. In this article, the abrasive waterjetmachining process is proposed because of its advantages in terms of high production rates, absenceof thermal damage and respect for the environment. In this way, it was possible to select parameters(stand-o  distance, traverse feed rate, and abrasive mass flow rate) that minimize the characteristicdefects of the process such as taper angle or the identification of di erent surface quality regions inorder to eliminate striations caused by jet deviation. For this purpose, taper angle and roughnessevaluations were carried out in three di erent zones: initial or jet inlet, intermediate, and final or jetoutlet. In this way, it was possible to characterize di erent cutting regions with scanning electronicmicroscopy (SEM) and to distinguish the statistical significance of the parameters and their e ects onthe cut through an analysis of variance (ANOVA). This analysis has made it possible to distinguishthe optimal parameters for the process.
