“…This machining was performed by an abrasive water jet machine, Finecut FAW400, which is designed to create a small AWJM beam which also seems to have an improved influence on the kerf.. The results presented by Uthayakumar showed a ten times higher kerf taper compared to the one machined in this investigation [5].…”

“…The geometrical aspects of the AWJM cut are of great importance too since the water jet beam greatly influence the geometry of the kerf. This was investigated by Uthayakuma et al who showed that the wall inclination could be controlled by the traverse speed and water jet pressure when machining Inconel 600 [5]. It was further shown that the material removal rate mainly was controlled by the water jet pressure and abrasive particle velocity.…”

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.

“…Abrasive water jet machining (AWJM) has got its popularity primarily because there is no friction or excessive heat formation and the surfaces produced are not exposed to high temperature [3]. High speed abrasive particles in the form of a slurry carries out the high speed micro cutting operation [4].…”

“…AWJM studies have been conducted in various metals and Inconel 718 is one of the popular alloys which has been studied. Kerf dimensions and properties in the AWJM of Inconel 718 has been widely reported [4] [5]. From popular literature it is established that jet pressure is a significant factor affecting the process rate.…”

This article details the methodology for the development of a multi objective optimization model for the abrasive water jet machining of Inconel 617. Genetic algorithm is the tool used for the optimization process. Abrasive water jet drilling of Inconel 617 is conducted using the Taguchi design of experiments. The various input factors considered are water pressure, abrasive flow volume and standoff distance. The responses selected for this study are overcut, circularity and drill rate. A simultaneous multi optimization model is developed using genetic algorithm. The optimization is done with four stages where in different weightages are added to the input factors and the results have been reported.

“…A nickel based super alloy Hastelloy C-276 with 30% of chromium and molybdenum weight makes the alloy more corrosive resistant. In this research an advanced machining process EDM is used for machining of hastelloy C-276 [1].In EDM process the material removal is based on an interrupted electric spark discharges among the electrode (cathode) and the Material (anode) which was submerged in dielectric fluid. Due to high temperature of spark in the machining zone the material is removed from the work piece due to high temperature of spark in the machining zone .The thermoelectric energy is formed between work piece and an electrode submerged in dielectric fluid with a transmission of electric current [2].…”

Due to development in machining science the use of composites and alloys is a great deal for every industry. Hastelloy C276 the most versatile corrosion resistant nickel based super alloy which is used for industrial applications is considered for doing the experiments .The high nickel and molybdenum content provides better corrosion resistance at extreme environments. In this report, the experiments are performed by using Taguchi L18 technique and their results are used for performance of each process parameters on their output responses. The process parameters considered for experimentation are discharge current, pulse- on- time, type of electrode and pulse off time for the output responses of material removal rate and surface roughness. Eco-friendly (drinking water) is used as a dielectric fluid. The experiments are designed and conducted using Taguchi L18 technique and analyze the influence of each process parameters on machining performance characteristics. Further, mathematical equations were developed using the statistical software MINITAB17.0.ANOVA is used for analyzing the experimental results obtained. It was observed from the response table that the average values of MRR and SR for pulse on time, discharge current, electrode are identified as important process parameters.
