“…The authors highlighted that with a considerable reduction of up to 0.5 mm of distance, the upper cutting width (Wt) is considerably reduced, decreasing the conicity ( Figure 10). This is in line with the results presented by Youssef et al [56]. It is worthy of note-how a reduction in the standoff distance produces a decrease in the radius of the area affected by erosion (IDR) due to the initial impacts of the abrasive particles.…”

The bonding of metallic alloys and composite materials in the form of a hybrid structure is a line of great interest for the current industry. The different machinability of both materials requires a specific machining process. Abrasive water-jet machining (AWJM) is an excellent technology for the simultaneous machining of both materials. However, defects at the micro and macro-geometric level have been detected in several scientific articles. In this review, a detailed study of the two main defects in metals, composite materials and hybrid structures has been developed. The conclusions of several scientific articles have been exposed for a better understanding of the topic in articles between 1984 and 2020. The influence of the cutting parameters on the reduction in kinetic energy of the water jet and the order of stacking of the materials in the hybrid structure is the main objective in order to minimize these defects. Cutting parameter optimization studies, predictive model proposals, process-associated defects and evaluation methodologies have been discussed. The aim of this article is to set a solid background on AWJM machining in hybrid structures and on the influence of cutting parameters on generated defects and machining strategies to obtain the best results at a macro and micro-geometric level.

“…Drilling, milling, sawing, and wire cutting are methods of traditional mechanical processing technologies that can harm materials by causing fractures, rips, and delamination [ 10 , 11 ]. Therefore, researchers developed novel processing technologies, such as laser processing, abrasive water-jet processing [ 12 ], electrical discharge machining (EDM) processing [ 13 ], ultrasonic vibration processing [ 14 ], novel processing technologies, etc. However, due to CFRP’s high strength, high hardness, high wear resistance, multi-layer diverse materials, and other variables, as well as the properties of inhomogeneity and anisotropy, it becomes a challenging material to process.…”

“…The EDM process, on the other hand, produces little mechanical damage but has low machining efficiency and poor machining accuracy. Although the ultrasonic vibration processing method reduces cutting force, fiber delamination pull-out and internal cracking still occur [ 12 , 13 , 14 ].…”

Due to its exceptional advantages, such as high specific strength, high specific modulus, and good fatigue resistance, carbon-fiber-reinforced plastic (CFRP) is frequently utilized in aerospace, aviation, automotive, rail transportation, and other areas. Composite components typically need to be joined and integrated. In the equipment manufacturing industry, the most used methods for processing composite components are cutting, drilling, and surface treatment. The quality of CFRP is significantly impacted by traditional mechanical processing, causing flaws like delamination, burrs, and tears. Laser processing technology has emerged as a crucial method for processing CFRP for its high quality, non-contact, simple control, and automation features. The most recent research on the laser processing of CFRP is presented in this paper, supporting scientists and engineers who work in the field in using this unconventional manufacturing technique. This paper gives a general overview of the key features of laser processing technology and the numerous machining techniques available. The concepts and benefits of laser processing technology are discussed in terms of the material properties, mode of operation, and laser characteristics, as well as the methods to achieve high efficiency, low damage, and high precision. This paper reviews the research development of laser processing of carbon-fiber-reinforced plastics, and a summary of the factors affecting the quality of CFRP laser processing. Therefore, the research content of this article can be used as a theoretical basis for reducing thermal damage and improving the processing quality of laser-processed composite materials, while, on this basis, we analyze the development trend of CFRP laser processing technology.

“…Therefore, non-conventional machining processes can be an alternative in order to improve the final performance of the process and minimize its environmental impact. Processes such as abrasive water jet machining or laser machining are alternatives that are currently being widely studied [ 14 , 15 , 16 ]. Nevertheless, defects associated with both processes hinder the accuracy of the drilling process of composite materials [ 17 , 18 ].…”

Design and Analysis of CFRP Drilling by Electrical Discharge Machining

The novelty of EDM machining as a drilling operation for composite materials means that there is no consensus on the influence of the parameters that optimise the final quality. For these reasons, a characterisation of the EDM drilling process of a unidirectional composite material has been developed. The influence of several cutting parameters has been related to the quality of the final hole obtained. Thus, macrogeometric aspects in terms of conicity and final diameter and microgeometric aspects in terms of surface quality have been evaluated. In addition, the final state of the material and the wear of the electrode have been evaluated by visual inspection, allowing the range of cutting parameters that offer the best performance to be established. Finally, a series of contour diagrams based on predictive models have been obtained to establish a direct relationship between input and output variables.
