“…• The presented methodology provided fundamental understanding of air-driven hot SiC particles in HAJM process. The experimental results obtained by this study would be helpful to process engineers toward the selection of an alternative effective method for machining in modern manufacturing industries with the approach taken in Jagannath et al [49] for abrasive hot air jet machining (AHAJM), Patel and Tandon [51] for thermally enhanced abrasive water jet machining (TEAWJM).…”

“…It is clearly seen from Fig. 9b that the tapper angle linearly varies with abrasive temperature having a slight effect on it, which may possible due to more plastic deformation [49] on top surface of the work part in comparison with the subsurface of quartz material. Figure 9c shows that the taper angle of hole made on quartz appears to have an increment trend with an increase in the distance between the nozzle and workpiece (called standoff-distance, SOD).…”

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.

“…Impinging abrasive along with the jet of hot air is another novel method of machining on glass. Jagannatha et al [15] performed the machining on glass by combining abrasives with hot air jet to study the material removal rate and surface roughness using one factor at a time approach. It was observed that MRR directly depends on feed rate, abrasive flow rate, velocity of abrasives and diameter of the nozzle.…”

Glass, being considered as hard and brittle material is very difficult to machine into desired shapes. The readily available conventional machining process does not provide good surface finish thus requires additional machining process. This paper reviews the different existing non conventional machining process accessible till today for the machining of glass materials. This paper also discusses the advantages and disadvantages of the existing non conventional machining processes. The various hybrid non conventional machining processes are also studied with focus on machining output characteristics like MRR, surface finish, tool wear rate. This paper summarizes the selection of hybrid non conventional machining processes for the various type of glass.

“…AJM of the planar areas with oscillating target material and fixed nozzle was carried out by Ghobeity et al [9] using both masked and unmasked methods. Abrasive hot air jet machining of soda lime glass was successfully implemented by Jagannatha et al [10] to study the impact of air temperature on the responses using Taguchi method.…”

Abrasive Jet Machining (AJM) is a promising unconventional modern machining process used to machine hard and brittle materials. This paper focuses on machining of borosilicate-glass work piece with various grits of zircon abrasives using normal and fluidised bed mixing chamber based AJM setups.The normal AJM setup is first designed and fabricated to conduct the experiments according to the Box-Behnken design of response surface methodology. Again, some modifications are made in the existing normal mixed chamber to fabricate the fluidized bed mixing chamber based AJM setup and experiments are carried out with the same input parameters on both the AJM setups. The SEM micrograph analysis is performed to study the impact-mechanism and crack-propagation due to AJM.
