“…This could be similar to the mechanism proposed and modelled in Ref. [9]. Since waviness occurs in the cutting direction as well for the width, it is not unreasonable that these two effects are coupled.…”

“…When the water jet strikes the surface, an erosion process takes place which results in material removal. The water jet cutting technology has been developed during the past 20 years and a lot of attention has been paid to investigate the water jet beam by simulations [15,16]. A frequently reported theme in the literature involves how to set the machining parameters in order to create a straight cut and diminish the kerf that is created at the AWJ inlet [17].…”

Electrical discharge machining (EDM) is considered as an efficient alternative to conventional material removal concepts that allows for much higher material removal rates. However, EDM generates unwanted features such as re-cast layer (RCL), tensile residual stresses and a rough surface. In order to recover the surface integrity, different post processes has been compared: high-pressure water jet (HPWJ), grit blasting (GB) and shot peening (SP). Surface integrity has been evaluated regarding microstructure, residual stresses, chemical content and surface roughness. The results showed that a combination of two post processes is required in order to restore an EDM processed surface of discontinuous islands of RCL. HPWJ was superior for removing RCL closely followed by grit blasting. However, grit blasting showed embedded grit blasting abrasive into the surface. Regarding surface roughness, it was shown that both grit blasting and HPWJ caused a roughening of the surface topography while shot peening generates a comparably smoother surface. All three post processes showed compressive residual stresses in the surface where shot peening generated the highest amplitude and penetration depths. However, the microstructure close to the surface revealed that shot peening had generated cracks parallel to the surface. The results strongly state how important it is to evaluate the surface at each of the different subsequent process steps in order to avoid initiation of cracks.

Nowadays, the abrasive water jet (AWJ) technology is much in use for cutting materials into complex shapes with high dimensional accuracy. The objective of the present paper is to study the topography as well as the roughness of the surfaces in friction stir welded (FSW) joints, machined by AWJ. It discusses machinability of the FSW joints by AWJ. Subsequently, this paper makes a critical analysis of the surface properties by optical profilometer. Top and bottom surfaces, created by FSW, have also been analyzed using an optical 3D measurement system to determine the morphology and topographic parameters. FSW possesses favourable joining properties and generates a minimum heat-affected zone (HAZ) because of its comparatively low temperature coalescence. Three friction stir welding samples were prepared at 500, 710 and 1000 rpm with a welding speed of 40 mm/min on AA 6101-T6. After analysis, it was found that the sample prepared at 500 rpm and with welding speed of 40 mm/min produces a surface fit for industrial applications in terms of surface roughness and dimensional accuracy. It has also been observed that unlike other conventional or non-conventional processes, no HAZ is generated during the cutting of FSW joints by using the AWJ technology.
