“…The mechanism of abrasive flow machining is similar to erosive wear, and the effect of machining is achieved by the micro-cutting action generated by the collision between particles in the abrasive flow and the workpiece surface. 17–20 If the abrasive particle is regarded as a micro-tool, the angle and speed of the micro-tool, when it collides with the workpiece surface under the action of the flow field, are randomly distributed. 21 The horizontal component of the micro-tool force mainly causes the plowing damage to the target, and the vertical component mainly causes the impact damage.…”

In order to study the machining mechanism and process of abrasive flow machining for the titanium alloy artificial joint surface, the abrasive flow machining experimental platform and the curved surface profiling flow channel were established for the machining. The influence of various process parameters (abrasive particle size, abrasive particle concentration, and processing time) and interaction factors on surface roughness and surface micro-topography of the workpiece was quantitatively evaluated through response surface analysis, and a surface roughness prediction model was established. The experimental results show that coverage constraint abrasive flow machining can significantly improve the surface quality of the titanium alloy artificial joint surface, thereby improving the wear resistance and service life of the artificial joint. Using abrasive flow machining with a smaller abrasive particle size and a larger concentration can obtain smaller surface roughness. Under the experimental conditions, the influence of process parameters on the surface roughness is in descending order of processing time, abrasive particle concentration, and abrasive particle size. And the interaction of processing time and abrasive particle size is more effective during processing. The research results can provide the basis for optimizing the flow channel structure for the abrasive flow machining of the titanium alloy artificial joint surface and have a certain guiding significance on the process optimization.

“…Under normal conditions, this value is lower, which means that the method of machining materials being discussed may be considered as relatively accurate. Given the above, AWJ, which is a universal technological tool, provides itself with a wider range of machining applications, enabling the shaping of many types of materials, such as metals and its alloys [ 14 , 15 , 16 , 17 , 18 , 19 ], ceramic, glass [ 20 ], composites [ 21 , 22 ], flammable materials, leather, and natural stone-based materials [ 23 ], as well as regenerating the cutting ability of grinding tools [ 24 ]. Nevertheless, there is still a need for further research related to this technology in order to increase the efficiency of material machining.…”

Influence of Variable Radius of Cutting Head Trajectory on Quality of Cutting Kerf in the Abrasive Water Jet Process for Soda–Lime Glass

The main innovation of this article is the determination of the impact of curvature of a shape cut out in a brittle material using an abrasive water jet (AWJ) process as an important factor of the machined surfaces. The curvature of a shape, resulting from the size of the radius of the cutting head trajectory, is one of the key requirements necessary for ensuring the required surface quality of materials shaped by the abrasive water jet process, but very few studies have been carried out in this regard. An important goal of the experimental studies carried out here and presented in this work was to determine its influence on the quality of the inner and outer surfaces of the cutting kerf. This goal was accomplished by cutting the shape of a spiral in soda–lime glass. For such a shape, the effect of radius of the trajectory of the cutting head on selected parameters of the surface texture of the inner surface of the cutting kerf (IS) and the outer surface of the cutting kerf (OS) was studied. The obtained results of the experimental studies confirmed that the effect of the curvature of the cut shape is important from the point of view of the efficiency of the glass-based brittle material-cutting process using AWJ. Analyses of the surface textures of the areas located in the upper part of the inner and outer surfaces separated by the use of AWJ machining showed that the OS surfaces are characterized by worse technological quality compared with IS surfaces. Differences in the total height of surface irregularities (given by St amplitude parameter), determined on the basis of the obtained results of the measurements of both surfaces of the cutting kerf, were as follows: ΔStr = 50 = 0.6 μm; ΔStr = 35 = 1 μm; ΔStr = 15 = 1.3 μm. The analysis of values measured in areas located in the more sensitive zone of influence of the AWJ outflow proved that the total height of irregularities (St) of the OS was higher. Differences in the total heights of irregularities for inner and outer surfaces of the cutting kerf were as follows: ΔStr = 50 = 2.1 μm; ΔStr = 35 = 3 μm; ΔStr = 15 = 14.1 μm, respectively. The maximum difference in the total heights of irregularities (St), existing between the surfaces considered in a special case (radius 15 mm), was almost 20%, which should be a sufficient condition for planning cutting operations, so as to ensure the workpiece is shaped mainly by internal surfaces.

“…Under such circumstances, the effective utilization of experimental, modeling, and optimization methodology makes possible a greater improvement in decision-making with new technological solution that can simultaneously satisfy and control the several distinctive as well as contradictory objectives (multi-objective) in order to make the HAJM process as an excellent choice for machining of advanced engineering ceramic and quartz materials. Several statistical and computational approaches such as MRA [1][2][3], RSM [4][5][6][7][8][9], ANN [10][11][12][13] have been applied for predictive modeling and Taguchi method [14][15][16][17][18], GRA [19][20][21][22][23][24][25], desirability function approach of RSM [26][27][28][29][30][31][32], PCA [33,34], TOPSIS [35], GA [11,12,36,37], PSO [38,39] have been employed for parametric as well as process optimization in abrasive jet machining with the help of carrier gas or liquid medium. Extensive studies have been reported by employing various experimental designs, modeling techniques, and optimization approaches in order to assess or investigate th...…”

This study aims to analyze the accomplishment of cutting performance in hot abrasive jet machining (HAJM) of hardstone quartz concerning surface roughness, taper angle, and material removal rate. Fifteen sets of experimental trials were conducted by considering three cutting parameters (air pressure, abrasive temperature, standoff-distance) based on Box-Behnken's design of experiments. Additionally, response surface methodology, analysis of variance, and statistical technique (here, desirability function approach) followed by computational approach (here, genetic algorithm) are, respectively, employed for experimental investigation, predictive modeling, and multi-response optimization. Thereafter, the effectiveness of proposed two multi-objective optimization techniques is evaluated by confirmation test and subsequently, the best optimal solution is used for cost analysis to rationalize the usefulness of hot abrasives in AJM process with an intension to raise the awareness in the manufacturing industry. Based on results, application of hot abrasives in AJM process has shown an attention in enhancing the cutting performance for material removal.
