State of the art research - WJ-AWJ technology in aerospace and automotive applications: capability of cutting complex parts

Abstract Since its discovery in mid 19th century, various papers regarding waterjet processes have been published, making this technology mature from the research standpoint. The goal of this review is to highlight advantages and issues of waterjet and abrasive waterjet basing on previous studies, as well as to provide statistical information about the quoted papers. This research is focused on three main material classes (metallic alloys, composite materials, soft materials), with particular regard to aerospace- and automotive- related applications. One of the most interesting researches about cutting optimization and performances in milling complex 3D features is here summarized, considering also advanced and promising materials for the aerospace field such as CFRP/Ti stacks. An insight regarding sustainability-related processes as metallic alloys remanufacturing and tyres recycling is also provided. Finally, the paper also presents an overview on the current industrial employment of the aforementioned technologies, listing some companies and their most attracting solutions
