Development of future aero engine components based on new design strategies utilising topological optimisation and additive manufacturing has in the past years become a reality. This allows for designs that involve geometries of "free form" surfaces and material combinations that could be difficult to machine using conventional milling. Hence, alternative manufacturing routes using non-conventional high energy methods are interesting to explore. In this investigation, the three high energy machining methods abrasive water jet machining (AWJM), electrical discharge machining (EDM) and laser beam machining (LBM) have been compared in terms of surface integrity to the reference, a ball nosed end milled surface. The results showed great influence on the surface integrity from the different machining methods. It was concluded that AWJM resulted in the highest quality regarding surface integrity properties with compressive residual stresses in the surface region and a low surface roughness with texture from the abrasive erosion. Further, it was shown that EDM resulted in shallow tensile residual stresses in the surface and an isotropic surface texture with higher surface roughness. However, even though both methods could be considered as possible alternatives to conventional milling they require post processing. The reason is that the surfaces need to be cleaned from either abrasive medium from AWJM or recast layer from EDM. It was further concluded that LBM should not be considered as an alternative in this case due to the deep detrimental impact from the machining process.

“…Moreover, it may also generate micro-crack at the inner surface of the hole and in case of composite materials it may also lead to delamination [5]. Therefore, the conventional machining methods cannot be used for creation of holes in these materials in acceptable tolerance limits because of improved mechanical properties [6,7].…”

Abstract-Recent advances in microfabrication are characterized by a progressive miniaturization leading towards higher integration. The fabrication of precise hole in different materials is one of the most challenging tasks in manufacturing industry. Since holes are prepared in the end product therefore the rejection of product due to poor hole quality is not acceptable in modern manufacturing processes. In this study, a detailed analysis of different hole making techniques has been elaborated so that a manufacturing engineer can get a broad guideline regarding the merits and demerits of different hole making processes.
