Abstract 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.

1 Introduction With today’s technologies, one of the important challenges for manufacturing industry is to provide workpieces with specified quality characteristics in the required quantity and in the fastest and most cost-effective way possible. Therefore, the improvement in the machining of newer materials and alloys becomes an absolute necessity in manufacturing process. Day-by-day, advanced engineering ceramics and quartz materials have increasingly widened their use in manufacturing sectors like aerospace, defense, manufacturing, automobile, electronic, and nuclear industries. These materials are extensively employed in different industrial applications to attain high performances due to their favorable characteristics such as lightweight, more excellent resistance Technical Editor: Adriano Fagali de Souza. * Sudhansu Ranjan Das [email protected] 1

to wear, high specific strength, and high-temperature resistance than conventional materials [1]. Lightweight materials are mechanically consistent with lesser manufacturing costs. In the viewpoint of commercial production, the traditional machining techniques are incompetent to machine these materials for achieving the required accuracy as well as precision, i
