Abstract:
Waterjet technology development for 600-MPa (87-Ksi) operations involves efforts on machining process development, pumps, plumbing, nozzles, and machining systems development. In this paper, data will be presented on cutting with water and abrasive waterjet at these elevated pressures. The effects of waterjet (WJ) and abrasive waterjet (AWJ) parameters on cutting rates of several materials are analyzed. It is observed that the power required for cutting is reduced as the pressure increases. Sheet metal and composites can be cut effectively with waterjets. The quality of the cut surfaces, however, improves by increasing pressure, adding abrasives, and operating at optimal standoff distances.

Abstract:
Abrasive waterjet is widely used for mass-cutting during coal mining or other mining process. Such a cutting process involves complex fluid–solid coupling, which require an effective method capable of simulating the large deformation and spalling of materials. This paper uses method of smoothed particle hydrodynamics (SPH) to establish a model to simulate the cutting process of coal seams by abrasive waterjets. In our SPH model, both fluid and solid are discretized with SPH particles. These particles are different in physical properties representing waterjet, abrasive particles and target materials. The waterjet is treated as viscous fluid and the coal (as a target material) is modeled as a brittle solid material. All these SPH particles of various medium are governed by the Navier–Stokes (NS) equations. Our established SPH model is then applied to study the efficiency of coal cutting using different waterjet formations. The results show that the cutting efficiency of the abrasive waterjet is higher than that of the standard waterjet. Our SPH model is capable of reveal the detailed interactions of the micro waterjet abrasive particles with the particles on the surface of coal. It enables the study on the mechanisms of coal seam breaking and cutting processes. It provides an effective computational tool for improving the efficiency of coal mining and of the development of new techniques for coal mining.

Abstract:
The abrasive mixing variables, such as the abrasive and water flow rates and the focus geometry parameters, determine the profitability of an abrasive waterjet system. In this study, the mixing efficiency characteristics in abrasive waterjet rock cutting were investigated. To demonstrate comprehensively the efficiency reduction due to collision during abrasive mixing, the chance of collision was expressed as the distance between the abrasive particles in the focus. The mixing efficiency was then assessed by utilizing the empirical relationship between the experimental results and the developed model. Based on the particle density and the velocity, the closer particles showed higher chances of collision, thus yielding a reduced cutting performance. Using the distance between particles model, the optimum abrasive flow rate and the cutting performance of abrasive waterjet systems can be estimated. This developed model can be used for the design selection of abrasive flow rate and systems for the cost-effective use of abrasive waterjets.

Abstract:
An experimental investigation was conducted to investigate the influence of abrasive waterjet parameters on the volume removal rate in abrasive waterjet turning. Abrasive mass flow rate, abrasive particle size, waterjet pressure, and orifice diameter were the principal variables that were investigated. Limited tests were also conducted with abrasive mixtures. The results show that the volume removal trends in abrasive waterjet turning are similar to those in linear cutting with abrasive waterjets. Increasing waterjet pressure, orifice diameter, and abrasive flow rate generally resulted in an increase in volume removal rate. However, the volume removal rate levels off either due to volume sweep rate limit or due to the abrasive waterjet limit. The results also suggest a potential for optimizing the abrasive flow rate and abrasive composition. The volume removal rate showed only a weak dependence on the abrasive particle size.

Abstract:
Abrasive-waterjets (AWJs) are formed by mixing high-pressure (up to 400 MPa) waterjets (0.1 to 1 mm in diameter) with abrasive particles in mixing tubes with typical 1/d ratios of 50 to 100. The pressure of the waterjet influences the overall performance of the abrasive-waterjet cutting system through operational and phenomenological effects. Higher pressures result in lower hydraulic efficiency, more frequent maintenance, high wear rates of mixing tubes, and fragmentation of particles before they exit the nozzle. However, with high pressures, deeper cuts can be obtained and higher traverse speeds can be used. Consequently, the hydraulic power is best utilized at an optimum pressure, which is a function of all other parameters as well as the application criteria. This paper presents data and analyses on the effect of pressure on nozzle operational characteristics, i.e., jet spreading characteristics, abrasive particle fragmentation, suction capability, wear of mixing tubes, and mixing efficiency. The effect of pressure on the parameters of cutting performance is discussed with example data. These parameters are depth of cut, specific area generation, maximum cutting traverse rate, surface waviness, and cost of cutting. Optimal pressure examples presented in this study indicate that pressures over 240 MPa are required for efficient abrasive-waterjet performance in metal cutting.

Abstract:
Abrasive waterjet (AWJ) cutting is a manufacturing technique, which uses a high-speed waterjet as the transport medium for abrasive particles to erode and cut through metal workpieces. The use of abrasives has significant environmental impacts and leads to the high operating costs of AWJ cutting. Therefore, it is important to investigate whether other metal cutting approaches can perform the same tasks with reduced environmental and economic impacts. One such manufacturing innovation is water droplet machining (WDM). In this process, the waterjet, which is immersed in a sub-atmospheric pressure environment, is discretized into a train of high velocity water droplets, which are able to erode and cut through the metal workpiece without abrasives. However, the cutting velocity of WDM is two orders of magnitude slower than AWJ. In this paper, a comparative life cycle and life cycle cost assessments were performed to determine which waterjet cutting technology is more beneficial to the environment and cost-efficient, considering their impacts from cradle to grave. The results show lower environmental and economic impacts for AWJ compared to WDM due to the AWJ’s ability to cut more metal over the service life than the WDM. Further sensitivity analyses give insight into how the change in abrasive rate is the most sensitive input for the AWJ, whereas the machine lifetime and electricity usage are the most sensitive inputs for the WDM. These results provide a valuable comparison between these alternative waterjet cutting technologies.

Abstract:
This paper addresses the wear characteristics of the mixing tube of an abrasive-waterjet nozzle. An effective nozzle material should possess high values of both hardness and toughness. The mixing tube, which is where the abrasives are mixed, accelerated, and focused with the high-pressure waterjet, is the component in the abrasive-water jet nozzle that receives the greatest wear. Accelerated wear tests were conducted on relatively soft (steel) mixing tubes using a typical soft abrasive (garnet sand) and on harder (tungsten carbide) tubes using a harder abrasive material (aluminum oxide). A wide range of candidate tool materials, including several carbides and ceramics, was also tested using actual machining parameters. The tungsten carbide grades exhibited greater longevity than the harder ceramics, such as boron carbide, when garnet abrasives were used. The reverse trend was observed with aluminum oxide abrasives. Wear trends suggest that the wear mechanisms along the mixing tube change from erosion by particle impact at the upstream sections to abrasion at the downstream sections. Linear cutting tests were also conducted on several candidate nozzle materials to gain more information related to wear performance. It was found, for example, that the binder in tungsten carbide, which controls these properties, is a critical factor that also controls the lifetime of tungsten carbide mixing tubes.

Abstract:
Abrasive waterjets are being increasingly used in civil engineering for rock and concrete cutting, particularly for the demolition or repair of old structures. The energy of an abrasive waterjet is primarily provided by the accelerated abrasive. The momentum transfer during mixing and acceleration determines the abrasive velocity, which affects the cutting performance. Meanwhile, the geometry of the focus at which mixing occurs influences the momentum transfer efficiency. In this study, the effects of the focus geometry on the optimum abrasive flow rate (AFR) and momentum transfer characteristics in hard rock cutting were investigated. Experiments were conducted using granite specimens to test the AFR under different focus geometry conditions such as diameter and length. The results show that the focus geometry significantly affects the maximum cutting depth and optimum AFR. The maximum cutting energy was analyzed based on the cutting efficiency of a single abrasive particle. In addition, the momentum transfer parameter (MTP) was evaluated from the empirical relationship between the maximum energy and the cutting depth for granitic rocks. Accordingly, a model for estimating the MTP based on the AFR was developed. It is expected that the results of this study can be employed for the optimization of waterjet rock cutting.

Abstract:
The article presents the basic parameters characterizing the abrasive water jet cutting, such as: water pressure (pw), cutting speed (vf), abrasive mass flow rate (ma) and the distance between forming nozzle and the cut material (l). Each of the mentioned parameters of the cutting process has been described in a separate subsection. The authors of the article focused primarily on the aspects related to the possibility of achieving maximum efficiency of the machining process while maintaining the assumed quality of cutting for individual cutting parameters. A detailed analysis of the topic was enabled the authors own research and an available literature on this subject. A closer understanding of the phenomena accompanying the abrasive waterjet cutting (AWJ) process and obtaining characteristics that would describe the influence of the tested output parameters in the function of input parameters will enable optimization of AWJ cutting process.

Abstract:
Within the oil and gas industry on offshore installations in the North Sea, several oil wells are closing in on the brink where they no longer are being profitable to keep producing from. When that day comes the oil wells are closed off and the boreholes are plugged with cement. Before the holes can be cemented shut the companies need to remove all their equipment that has been used for underwater exploitations of the well and if applicable remove the above water installation as well. This includes removing the casing that the holes are lined with which main purpose is to prevent the hole from collapsing on the production line and to prevent oil and gas leaks into the surroundings. This thesis focuses on removal of the borehole casing.  When performing this task problems have been raised regarding corrosion on the casing couplings, making them very hard to separate. When this problem occurs, the need for an alternative method to split them is necessary. As of today this operation is performed by cold cut sawing or with a beveling machine. This is a highly time consuming task and an alternative method to perform a faster cut is wanted. This degree work investigates the possibilities of doing this using the benefits of abrasive water jet (AWJ) cutting. The major concerns on using this technic is whether it is fast enough and if it is possible to perform in accordance with the fire and explosive hazards on a hydrocarbon producing installation. As a reference the maximum cut time is set to one minute. Calculations on theoretical cutting speeds as well as physical testing on the AWJ method has been performed and evaluated. The investigations show that the method does have the possibilities of making the cut within the target time.  The work also contains a simple concept model on how the equipment could be constructed.
Inom olje- och gasindustrin på offshoreanläggningar i Nordsjön, närmar sig flera reservoarer randen där de inte längre är lönsamma att fortsätta producera från. När den dagen kommer pensioneras borrhålen och pluggas med en cementblandning. Innan hålen pluggas måste företagen ta bort all utrustning som har använts vid utvinningen av brunnen, både ovan och under ytan. Detta innefattar avlägsnande av casingen, som hålen är fodrade med, och vars huvudsakliga syfte är att förhindra att hålet kollapsar och skadar produktionsledningen, men även för att förhindra olje- och gasläckor till omgivningen. Denna avhandling fokuserar på borttagandet av casingen. När detta görs upplevs problem med att casingskarvarna är kraftigt korroderade vilket gör dem mycket svåra att separera. Detta är ett problem som efterfrågar en alternativ delningsmetod. I dag utförs den här operationen med antingen kallsågning eller med en avfasningsmaskin. Detta är en mycket tidskrävande uppgift och en metod för att utföra en snabbare delning önskas. Detta examensarbete är tänkt att undersöka möjligheterna att göra detta genom att använda fördelarna med abrasiv vattenskärning för att kapa rören. De största frågorna gällande denna metod är om den är tillräckligt snabb och om det är möjligt att utföra i enlighet med de brand- och explosionsrisker som finns på en kolväteproducerande installation. Som referens är målet för maximal skärtid satt till en minut. Beräkningar på teoretiska skärhastigheter samt fysiska tester på metoden har utförts och utvärderats. Undersökningarna visar på att metoden har möjligheter att göra snittet inom utsatt tid. Arbetet innehåller också en enkel konceptmodell på hur utrustningen skulle kunna konstrueras.

Abstract:
Abrasive waterjet (AWJ) cutting is one of the most recently developed manufacturing technologies. It is superior to many other cutting techniques in processing various materials, particularly in processing difficult-to-cut materials. This technology is being increasingly used in various industries. However, its cutting capability in terms of the depth of jet penetration and kerf quality is the major obstruction limiting its further applications. More work is required to fully understand the cutting process and cutting mechanism, and to optimise cutting performance. This thesis presents a comprehensive study on the controlled nozzle oscillation technique aiming at increasing the cutting performance in AWJ machining. In order to understand the current state and development in AWJ cutting, an extensive literature review is carried out. It has found that the reported studies on controlled nozzle oscillation cutting are primarily about the use of large oscillation angles of 10 degrees or more. Nozzle oscillation in the cutting plane with such large oscillation angles results in theoretical geometrical errors on the component profile in contouring. No published attempt has been found on the study of oscillation cutting under small angles although it is a common application in practice. Particularly, there is no reported research on the integration of nozzle oscillation technique into AWJ multipass cutting, which is expected to significantly enhance the cutting performance. An experimental investigation is first undertaken to study the major cutting performance measures in AWJ single pass cutting of an 87% alumina ceramic with controlled nozzle oscillation at small angles. The trends and characteristics of cutting performance quantities with respect to the process parameters as well as the science behind which nozzle oscillation affects the cutting performance have been analysed. It has been shown that as with oscillation cutting at large angles, oscillation at small angles can have an equally significant impact on the cutting performance. When the optimum cutting parameters are used for both nozzle oscillation and normal cutting, the former can statistically increase the depth of cut by 23% and smooth depth of cut by 30.8%, and reduce kerf surface roughness by 11.7% and kerf taper by 54%. It has also been found that if the cutting parameters are not selected properly, nozzle oscillation can reduce some major cutting performance measures. In order to correctly select the process parameters and to optimise the cutting process, the mathematical models for major cutting performance measures have then been developed. The predictive models for the depth of cut in both normal cutting and oscillation cutting are developed by using a dimensional analysis technique. Mathematical models for other major cutting performance measures are also developed with the aid of empirical approach. These mathematical models are verified both qualitatively and quantitatively based on the experimental data. The assessment reveals that the developed models conform well to the experimental results and can provide an effective means for the optimum selection of process variables in AWJ cutting with nozzle oscillation. A further experimental investigation of AWJ cutting of alumina ceramics is carried out in order to study the application of AWJ oscillation technique in multipass cutting. While high nozzle traverse speed with multipass can achieve overall better cutting performance than low traverse speed with single pass in the same elapsed time, it has been found that the different combination of nozzle traverse speed with the number of passes significantly affects cutting process. Optimum combination of nozzle traverse speed with the number of passes is determined to achieve maximum depth of cut. It has also demonstrated that the multipass cutting with low nozzle traverse speed in the first pass and a comparatively high traverse speed for the following passes is a sensible choice for a small kerf taper requirement. When nozzle oscillation is incorporated into multipass cutting, it can greatly increase the depth of cut and reduce kerf taper. The predictive models for the depth of cut in both multipass normal cutting and multipass oscillation cutting are finally developed. With the help of dimensional analysis, the models of the incremental cutting depth for individual pass are derived based on the developed depth of cut models for single pass cutting. The models of depth of cut for a multipass cutting operation are then established by the sum of the incremental cutting depth from each pass. A numerical analysis has verified the models and demonstrated the adequacy of the models' predictions. The models provide an essential basis for the development of optimization strategies for the effective use of the AWJ cutting technology when the multipass cutting technique is used with controlled nozzle oscillation.

Abstract:
This research work presents an optimisation of abrasive waterjet contour cutting process parameters with the objectives of maximising material removal rate, whilst minimising taper angle and surface roughness. This thesis contains an in-depth review of the systems behind abrasive waterjet machining and recent progress trends regarding its applications. The impacts of input parameters are investigated including traverse speed, waterjet pressure and abrasive mass flow rate against selected responses in abrasive waterjet contour cutting of austenitic stainless steel 304L. Experimental data is utilised to generate regression models in predicting responses, where the results are statistically evaluated to assess the percentage contribution of each parameter in the performance of contour cutting. Techniques, such as Taguchi and Response Surface Methodology, are employed to perform a single and multi-objective optimisation. Abrasive waterjets demonstrate similar responses in cutting curvature and straight line profiles during contour cutting. The study reveals that an increasing level of waterjet pressure and abrasive mass flow rate results in lower surface roughness, lower kerf taper angle and higher rate of material removal. Similarly, a lower rate of traverse speed achieves minimum surface roughness and kerf taper angle, whereas increasing its rate attains the maximum value of material removal rate.

Abstract:
Abrasive water jets have recently become a popular tool for mechanical machining. With its great advantages of geometric and material flexibility and its ability to cut hard-to-machine materials the technology is quickly spreading throughout many industries. With this near net-shape production becomes feasible, while significantly reducing the time necessary for secondary operations like programming, clamping, or tool changing. This allows a significant optimization of the overall manufacturing process chain. In this paper different approaches to increase the economic and technical efficiency of cutting with abrasive water jets are analyzed. Experimental analysis of the speed of abrasive particles show that the kinetic power of the particles mainly depends on the hydraulic power of the waterjet. Merely increasing the pressure of the jet did not yield any improvement in its acceleration capability. To obtain the most effective cutting performance a high level of hydraulic power through large nozzles should therefore be utilized. Additionally, recent advancements in cutting path control software have proven to significantly decrease the total ‘time to product’ and to increase the precision of the part. Those improvements in both software control and cutting power enable abrasive water jets to become an integral part of many industrial manufacturing processes. This will widen the scope of possible applications of this innovative and promising technology.

Abstract:
Fiber Metal Laminates (FML) are one of the most advanced engineered materials used in aerospace industry. The combination of metallic sheets interspersed in composite laminates in one hybrid material system provides higher impact and corrosion resistance when compared with their monolithic counterparts. However, due to the difference in machining responses for different material phases, conventional machining often induce damages and defects, affecting the cost and structural performance of the part. This research study investigates the machinability of thermoplastic Titanium Graphite (TiGr) FML. The feasibility and machinability of contouring thick (7.6 mm–10.5 mm) TiGr through Abrasive Waterjet (AWJ) process was studied in terms of machined kerf characteristics — taper ratio and surface quality. The effect of a wide range of process parameters was investigated such as geometric variables (mixing tube aspect ratio and orifice bore size), kinetic variables (water pressure, jet traverse speed) and abrasive load ratio on the machining quality. Predictive mathematical regression models were developed through Analysis of Variance (ANOVA) in order to optimize the process. Alongside, machined surface was examined to inspect the topological characteristics, material removal mechanism, and machining induced damage (micro-defects) and distortion through Surface Profilometry, Scanning electron and optical microscopy. A comparison was drawn between conventional and AWJ trimming of TiGr to demonstrate the superiority and high speed machining of AWJ with less damage.

Abstract:
Waterjet cutting is used in various fields and applications. Materials difficult to machine, small series production and complex geometry is easy to handle with this cutting process. Frozen food, leather and plastic as well as stone, glass and steel are materials which can be cut by waterjet or abrasive waterjet. The efficiency of the cutting technology is depending mainly on the pump system and the installed high pressure cutting equipment. Maximum working pressure, flow rate of water and the reliability of the high pressure pump influences flexibility, velocity and finally the costs of each cut. This paper presents the actual technical state of the art for waterjet cutting and gives an overview on cutting tests with ultra high pressure up to 800 MPa.
