The use of composite materials in the aerospace fields is increasing. In commercial aircraft such as the A380 and Boeing 787, these composite parts are arranged in the shape of monolithic or sandwich panels such as CFRP, CFRP/CFRP, CFRP/Aluminium, etc. However, their machinability poses several problems. The major problems observed are delamination, thermal degradation, tool wear, composite erosion by continuous chips of metallic materials, built up edge, etc.
In order to understand and avoid such damages, reduce the time of machining and improve the quality of surface finish and tool life, various machining processes have been used in the aeronautical fields. Among them are the CNC machine, one shot drilling and assembly and water jet machining. Nevertheless, the quality of machining is affected not only by the machining parameters, but also by the process of machining (CNC machine, water jet, etc) and the manufacturing process of the composite parts (autoclave, RTM, etc).
This special issue invites the submission of high quality research articles related to the machining of aerospace materials.
Suitable topics include but are not limited to:
- Machining of titanium, composite and aluminium alloys
- Drilling of composite materials and hybrid materials (CFRP, CFRP/Al, CFRP/Ti, etc)
- Trimming of composite materials
- Water jet cutting and machining of composites
- Machining of super alloys
- Non-traditional machining of aerospace materials
- Quality of machining
- Tool wear
- Numerical modelling of the machining
