Delamination Factor

High-strength environment-friendly metal-fiber laminates (MFLs) are increasingly used for primary structures for various engineering applications. The surface roughness variation and delamination factor of a titanium (Ti) metal-cored basalt/flax fiber laminate were investigated during abrasive water jet drilling (AWJD). The present AWJD investigation is to establish the correlation of four important process independent variables of WJP—water jet pressure, TS—traverse speed, QMFR—abrasive mass flow rate, and SOD—stand-off distance to the delamination factor (Fd-top) and surface roughness (Ra) of drilled hole. Central composite design (CCD) of L29 orthogonal array was used to perform the experimental observations. The statistical approach (ANOVA) was employed to determine the contribution of individual AWJD parameters to drilling operation. It is identified from experimental results that the water jet pressure is the most predominant process parameter and its contribution on Fd-top and Ra were 74.28% and 72.48%, respectively. Increasing the water pressure from low (160 MPa) to its higher range (320 MPa) showed that the surface roughness and delamination factor were reduced irrespective of other drilling parameters. Increased water pressure provides enough kinetic energy for abrasive particles to facilitate a higher penetration potential during the drilling process. Scanning Electron Microscope (SEM) images show the machining-induced damages like ploughing marks, uncut fibers, ridges, craters, matrix smearing, and delamination on an abrasive water jet drilled surface of prepared MFL.

The abrasive water jet machining is known as a cold cutting process and can be effective for developing cut in the bone in orthopedic surgery to prevent thermal necrosis. This research examined surface roughness and cutting quality of bovine femur bone using abrasive water jet machining. Furthermore, the effect of three parameters was studied including water pressure, traverse speed, and the type of abrasive particles. The feed rate of the abrasive particles was considered 100 g/min, and the levels obtained from pure water jet cutting, bone powder abrasive water jet machining, and sugar abrasive water jet machining were compared with each other. Application of bone powder as an abrasive particle caused improved cutting quality, when compared with pure water jet, and in the best case, it resulted Ra and Rz values of 7.36 and 54.76 μm, respectively at the pressure of 3500 bar and traverse speed of 50 mm/min. The minimum surface roughness was obtained using sugar abrasive particles at the pressure of 3500 bar and traverse speed of 50 mm/min. The values of Ra and Rz parameters measured at the most desirable state were 3.87 and 19.72 μm, respectively. The results suggested that use of sugar as an abrasive material, in comparison with pure water jet and bone powder water jet, resulted in improved cutting quality. Furthermore, elevation of water pressure and reduction of traverse speed had a significant effect on improving surface roughness.

This paper aims to develop a predictive model and optimize the performance of the abrasive water jet machining (AWJM) during machining of carbon fiber-reinforced plastic (CFRP) epoxy laminates composite through a unique approach of artificial neural network (ANN) linked with the nondominated sorting genetic algorithm-II (NSGA-II). Initially, 80 AWJM experimental runs were carried out to generate the data set to train and test the ANN model. During the experimentation, the stand-off distance (SOD), water pressure, traverse speed and abrasive mass flow rate (AMFR) were selected as input AWJM variables and the average surface roughness and kerf width were considered as response variables. The established ANN model predicted the response variable with mean square error of 0.0027. Finally, the ANN coupled NSGA-II algorithm was applied to determine the optimum AWJM input parameters combinations based on multiple objectives.

Metal Matrix Nanocomposites

This study investigated the effect of abrasive water jet kinematic parameters, such as jet traverse speed and water pressure, on the surface of magnesium-based metal matrix nanocomposites (Mg-MMNCs) reinforced with 50 nm (average particle size) Al2O3 particles at concentrations of 0.66 and 1.11 wt.%. The extent of grooving caused by abrasive particles and irregularities in the abrasive waterjet machined surface with respect to traverse speed (20, 40, 250 and 500 mm/min), abrasive flow rate (200 and 300 g/min) and water pressure (100 and 400 MPa) was investigated using surface topography measurements. The results helped to identify the mode of material disintegration during the process. The nanoindentation results show that material softening was decreased in nanocomposites with higher reinforcement content due to the presence of a sufficient amount of nanoparticles (1.11 wt.%), which protected the surface from damage. The values of selected surface roughness profile parameters—average roughness (Ra), maximum height of peak (Rp) and maximum depth of valleys (Rv)—reveal a comparatively smooth surface finish in composites reinforced with 1.11 wt.% at a traverse speed of 500 mm/min. Moreover, abrasive waterjet machining at high water pressure (400 MPa) produced better surface quality due to sufficient material removal and effective cleaning of debris from the machining zone as compared to a low water pressure (100 MPa), low traverse speed (5 mm/min) and low abrasive mass flow rate (200 g/min).

Abstract The paper deals with a study of relations between the measured Ra, Rq, Rz surface roughness parameters, the traverse speed of cutting head v and the vibration parameters, PtP, RMS, vRa, generated during abrasive water jet cutting of the AISI 309 stainless steel. Equations for prediction of the surface roughness parameters were derived according to the vibration parameter and the traverse speed of cutting head. Accuracy of the equations is described according to the Euclidean distances. The results are suitable for an on-line control model simulating abrasive water jet cutting and machining using an accompanying physical phenomenon for the process control which eliminates intervention of the operator.

The present paper describes an experimental study of abrasive water jet machining (AWJM) of Kevlar epoxy composite. Influence of process parameters namely stand-off distance, water pressure, traverse speed and abrasive mass flow rate on surface roughness and kerf taper is investigated. Taguchi orthogonal approach is applied to plan the design of experiments; and subsequent analysis of experimental data is done using analysis of variance (ANOVA). It is found that water pressure and traverse speed are most significant parameters followed by stand-off distance and abrasive mass flow rate influencing surface roughness and kerf taper. With increase in water pressure and decrease in traverse speed, kerf taper and surface roughness decreases.

Cutting Surface

Through the experiment of cutting 1060 Aluminum Alloy by Abrasive Water Jet (AWJ), the surface roughness of material which is cut by AWJ is controlled by the cutting work pressure, cutting stand-off distance, cutting traverse speed and the abrasive diameter which used in AWJ. Measuring the cutting surface roughness of 1060 Aluminum Alloy by stereomicroscope and surfagauge, among the factor which can affect the surface roughness, the cutting traverse speed play a dominant role to control the surface roughness in the process of cutting. As the result of the surface roughness of 1060 Aluminum Alloy at different cutting depth is different, which can be separated in two different zones (Smooth area and Rough zone). As the result of experiment, the abrasive diameter has little effect to change the surface roughness between two different zones. The surface quality of rough zone can be improved when change the diameter of abrasive: with the diameter of abrasive increase, the surface quality of rough zone become better. A higher cutting pressure can improve the surface quality of the cutting surface of 1060 Aluminum Alloy. While increase the cutting traverse speed in the process of cutting can decrease the surface quality of 1060 Aluminum Alloy cutting surface. In a certain range, increase the cutting stand-off distance of AWJ can decrease the surface roughness of the cutting surface, and the roughness of cutting surface will change little when the stand-off distance increases to a certain extent.

Study Results

In this paper, the effect of abrasive water jet cutting process on the surface character of medical implant SS316L was investigated. This research focuses on the effect of traverse speed during abrasive water jet cutting on the surface roughness and topography of medical implant material SS316L. In some study, it has been noted that the roughness of implant material correlates with the healing process of a sufferer in medical application. Furthermore, transverse speed has an important role in the manufacturing process that correlates directly with the ability of technic to produce a product at a definite time. Garnet was used as an abrasive material in this water jet cutting process. The process was taking place in room temperature with 3000Psi of water pressure. In this study, the surface roughness was examined at all point of depth of the cut surface in all of the transverse speed using Mitutoyo SJ 210, while the surface topography observed by Olympus BX53M optical microscope. The study results reveal that traverse speed has a significant effect on the surface roughness at the surface, middle, and bottom of the cut point. The Surface roughness increase as transverse speed.

This paper deals a set of studies performed on AA6063-TiC composites produced by adding 3%, 6% and 9% wt. of TiC in aluminium alloy 6063 and processed with abrasive water jet cutting that are formed with garnet abrasive of 80 mesh size. These studies are effectively meant to evaluate the surface roughness (Ra) of abrasive water jet cutting on various compositions of AA6063-TiC produced by stir casting route. Abrasive water jet cutting was carried out on cylindrical samples of various compositions of AA6063-TiC composites by varying traverse speed, stand-off distance and abrasive flow rate at three different levels. The experiments were performed using Taguchi’s L27 orthogonal array. Contribution of these parameters on the Ra was determined by ANOVA and regression analysis to optimize the process parameters for effective machining. Among the interaction effects, traverse speed and stand-off distance combinations contribute more to the Ra. The microstructures of machined surfaces were also analysed by scaning electron microscope images and F-profile plots.
