Abstract: In this paper, an attempt has been made to drill 'BK-7' using rotary ultrasonic machining (RUM). The effects of machining parameters namely feed, spindle speed and ultrasonic power were investigated on material removal rate (MRR) and chipping thickness (CT). Response surface methodology (RSM) was utilised for developing regression equations for output responses. The response observations were tested through analysis of variance (ANOVA) for recognising the significant input variables. The selected responses were found to be highly influenced by feed and exhibited opposite variation with increase in feed. Furthermore, the study also targets to improve the machining efficacy by optimising the machining parameters using desirability and particle swarm optimisation (PSO) approaches. Both the approaches were found to be equally viable. However, PSO exhibited an ease in obtaining the optimised solution with lesser time to cope up with industrial needs.
