Defect Analysis and Detection of Cutting Regions in CFRP Machining Using AWJM

Abstract: The use of composite materials with a polymeric matrix, concretely carbon fiber reinforced polymer, is undergoing further development owing to the maturity reached by the forming processes and their excellent relationship in terms of specific properties. This means that they can be implemented more easily in different industrial sectors at a lower cost. However, when the components manufactured demand high dimensional and geometric requirements, they must be subjected to machining processes that cause damage t… Show more

“…The jet can be composed of any liquid, but for economic and environmental reasons, the liquid used is usually a mixture of water and air. The water, by presenting a higher density, applies a higher impact pressure during machining [25,26].…”

“…In combination with reduced pressure, the jet does not have enough energy to obtain a clean cut (Figure 4). Thus, the intercollisions of the abrasive particles reduce its cutting capacity, producing a more eroded zone [35]. On the other hand, when the traverse speed increases its value, this trend for a hydraulic pressure of 250 MPa is totally opposite due to the increase in the kinetic energy of the water jet.…”

“…Therefore, advanced machining techniques using abrasive high-pressure water jet machining process are widely utilized to cut the high strength materials without thermal damage; this advanced machining technique is called abrasive water jet (AWJ). The main advantages of using AWJ in the manufacturing process are fewer recast layers, high cutting precision, and low cutting forces, and the lack of excess heat generated [9]. This machining technique has been adopted in production to process high-strength materials, such as stone, composite material, glass, etc.…”
