Computational approach for structural and thermal behavior of laser-machined micro-grooves on alumina ceramic using ANSYS Subhadip Pradhan, Samir Kumar Panda, Kalyani Panigrahi, Debabrata Dhupal Proceedings of the Institution of Mechanical Engineers Part E Journal of Process Mechanical Engineering, 2025 Heat affected zone on the micromachined material, a hindrance in achieving good precision and accuracy, which are adequate requirements for micromachined materials, is a drawback of nanosecond micromachining assisted by laser. The primary objective of this paper is to take into consideration a number of input parameters, such as the pulse width and the temperature of the laser beam, and study the effect that these parameters have on the heat flux generated as well as on the temperature distribution along the square grooves of 200 µm width and depth that are to be micro-machined on an alumina ceramic workpiece. However, processing of alumina ceramic on a micron-scale requires careful consideration to raise the quality standard. This will be accomplished by analyzing the data collected from the micro-machining process. Using the ANSYS® software, it is possible to visualize not only the region where heat is generated but also the way in which the input parameters influence the structural qualities of the micro machined groove surface. The many thermal models that have been constructed have revealed specific changes in the structural qualities that have had a significant impact on the upper width, the lower width, and the depth of the groove when applied to a variety of different parametric settings. Finally, developed analytical model is compared with the experimental models. The highest prediction error was found to be 1.68%, while, for constant 50 W power and 150–250 mm/s of speed, the average prediction error was determined to be 1.18%. As a result, the proposed model closely matches the experimental findings, and the proposed model can be used to estimate channel profile.
COMPARATIVE PERFORMANCE EVALUATION BETWEEN AJM AND HOT-AJM DURING MACHINING OF ZIRCONIA CERAMIC USING SILICON CARBIDE ABRASIVES SUBHADIP PRADHAN, SOUMYA RANJAN SAMANTARAY, DEBABRATA DHUPAL, SUDHANSU RANJAN DAS Surface Review and Letters, 2024 Abrasive jet machining (AJM) process is commonly used for cutting and drilling of brittle materials in which the phenomenon of material removal can be considered as mechanical erosion by the impingement of high-velocity abrasives. The focus of this research is to compare the performance and economic benefits of recently developed hot abrasive jet machining (hot-AJM) with traditional AJM techniques when machining zirconia ceramic using silicon carbide (SiC) grain particles. The modified AJM employed abrasive air jet (combination of hot abrasive and compressed air) to strike on the work surface for material erosion. Briefly, the cutting performance is investigated by comparing the technological characteristics like material removal rate, machining cost, and taper angle of the developed hole. Abrasive grain size, nozzle pressure, and stand-off distance are considered as the variable factors for machining trials in accordance with the design of experiments. The usage of hot abrasives in AJM improved the material erosion owing to the occurrence of plastic deformation followed by deep chipping on the machined surfaces. From the results, it was observed that the hot-AJM outperformed the normal AJM with regard to improved material removal, reduced dimensional deviation of hole and minimal machining cost. According to the findings of the cost assessment, the machining of zirconia ceramic using hot-AJM was more cost-effective than using normal AJM since it resulted 25% reduction in the total cost of production. The overall machining cost expenditure per unit in hot-AJM was lower (INR 123.12) than expenditure in traditional AJM (INR 153.47). Machining with hot-modified AJM, compared to normal AJM, offers a more techno-economically viable solution for enhancing machinability.
Experimental and simulation approach of surface generation on K-80 alumina ceramic by recently developed sustainable FB-HAJM using novel nozzle design Subhadip Pradhan, Debabrata Dhupal Proceedings of the Institution of Mechanical Engineers Part E Journal of Process Mechanical Engineering, 2022 K-80 alumina ceramic makes it challenging to machine them economically due to extreme hardness. Fluidized bed-hot abrasive jet machining (FB-HAJMing), in which a target profile is eroded by the impingement action of air-hot abrasive jet, which containing fine hot abrasive grains for machining of K-80 alumina ceramic materials without thermal damage. This study is intended to analyse kerf angle (KA), surface roughness (Rz) and material removal rate (MRR) using HAJMing process of K-80 alumina ceramic. Fifteen sets of experimental trials were conducted two times using tungsten carbide (WC) nozzle with and without internal thread. The identified three cutting parameters i.e., air pressure (P), abrasive temperature (T) and stand-off-distance (SOD), were considered for experimental design. Furthermore, the response surface methodology (RSM), statistical techniques (here, desirability function approach) followed by computational approach (here, genetic algorithm) are respectively employed for experimental investigation, predictive modelling and multi-objective optimization. Subsequently, confirmation tests evaluate the efficiency of the suggested two multi---objective optimization methods to rationalize the utility and awareness of the usefulness of hot abrasives in HAJMing. Moreover, computational fluid dynamics (CFD) modelling was utilized to develop a comprehensive relation between HAJMed profile geometry and erosive flow. Finally, the environmental ‘Pugh Matrix’ approach is proposed for the HAJMing process sustainability evaluation. The results indicated a desire to improve the cutting efficiency for material erosion by using hot abrasives in the HAJMing procedure. The most important parameter for surface roughness is abrasive temperature, while pressure is important for both KA and MRR. The use of hot abrasives in the FB-HAJM process has demonstrated a focus on improving the cutting performance for material removal. From an economic standpoint, the current study presents a technological criterion for feasible industrial applications of the FB-HAJM method, such as in aerospace, precision manufacturing, and biomedical field.
An Integrated Approach of Simulation, Modeling and Computer-aided Design of Hot Abrasive Jet Machining Setup Subhadip Pradhan, Debabrata Dhupal Journal of Advanced Manufacturing Systems, 2022 In the past few decades, sophisticated machining industries have rapidly improved in order to achieve the required shape of a part within a specific time while also not affecting material properties. Accuracy of machined components in all industries is important. In the case of subassemblies of components, geometrical accuracy of hole is vital. The researchers updated their machinery from time to time from this perspective. In the machining process, environment and time are the vital parameters that are mainly affected, so in this case, the design of experiments that are very useful in the machining region needs to be considered to overcome these challenges. This study aims to analyze the fabrication of hot abrasive jet machining (HAJMing) with different abrasive temperatures using fluidized bed system as well as accomplishment of cutting performance in hot-abrasive jet machining concerning target surface erosion. Additionally, this research study accomplishes the experimental study and computational fluid dynamics (CFD) technique for erosive footprint prediction extent in HAJMing constraints on target surface for intricately shaped tapered holes generation. The use of hot abrasives in the HAJM process has demonstrated an interest in improving cutting performance for material erosion. Moreover, this proposed experimental work contains the manufacturing, design and fabrication of hot abrasive jet machine (HAJM) using commercially available hardware and software. So, the components are manufactured indigenously as per the designed parameters for the purpose of improving the machining performance. Simulation for material erosion mechanism of HAJMing is used to obtain the nature of produced workpiece profile. Additionally, FB-HAJMing also deals with the sustainability assessment under environmental-friendly hot abrasive-assisted machining conditions.
Machining of aluminium nitride ceramic using developed hot abrasive jet machining: an experimental and simulation approach Subhadip Pradhan, Sourav Sanket Tripathy, Debabrata Dhupal Advances in Materials and Processing Technologies, 2022 This novel implementation will analyse the cutting performance of hardstone aluminium nitride with regards to roughness of the surface and material erosion in hot abrasive jet machining (HAJM). Forty five sets of tests have been carried out taking into account five machining constraints (compressed air pressure, compressed air velocity, abrasive temperature, abrasive grain size and percentage concentration of hot abrasives). To optimise the model and determine the conditions for maximising the erosion rate and minimising the surface roughness, a particle swarm optimisation (PSO) was used with experimental investigation as well as predictive modelling. The results were validated experimentally, and the results were well-established between test results and PSO forecasts. The nature of the produced target profile was obtained through CFD simulation in HAJMing. In addition, HAJMed surface microstructures were analysed with microscopic images. The results of RSM data have been validated by testing and RSM prediction. In addition, a multi-objective optimisation problem based on the empirical models was used and the multi-objective particle swarm optimisation (PSO) were determined. In AlN ceramic materials, the RSM with PSO determined the optimal machining restriction for an exact HAJMing condition.
