Optimization of Abrasive Life in Ultrasonic Machining

Based on two models of material removal in ultrasonic machining, developed in an earlier work, conditions for optimum abrasive life for the objective functions of minimum cost per unit volume of material removed, maximum production rate and maximum profit rate are presented. A simple nomogram is designed for the determination of optimum abrasive life. Sensitivity studies of production rate and profit rate functions are presented. An illustrative example highlights the application of the analysis.
