AB The incorporation of plastic matrix composite materials into structural elements ofthe aeronautical industry requires contour machining and drilling processes along with metallicmaterials prior to final assembly operations. These operations are usually performed usingconventional techniques, but they present problems derived from the nature of each material thatavoid implementing One Shot Drilling strategies that work separately. In this work, the studyfocuses on the evaluation of the feasibility of AbrasiveWaterjet Machining (AWJM) as a substitute forconventional drilling for stacks formed of Carbon Fiber Reinforced Plastic (CFRP) and aluminumalloy UNS A97050 through the study of the influence of abrasive mass flow rate, traverse feed rate andwater pressure in straight cuts and drills. For the evaluation of the straight cuts, Stereoscopic OpticalMicroscopy (SOM) and Scanning Electron Microscopy (SEM) techniques were used. In addition, thekerf taper through the proposal of a new method and the surface quality in different cutting regionswere evaluated. For the study of holes, the macrogeometric deviations of roundness, cylindricity andstraightness were evaluated. Thus, this experimental procedure reveals the conditions that minimizedeviations, defects, and damage in straight cuts and holes obtained by AWJM.
