The authors consider that this type of failure during ultrasonic cutting is due to a number of consecutive high impacts between the tool and the workpiece for long durations at a compara-tively high-cutting speed. Ultrasonic Machining (USM) and Ultrasonic Machining Tool: The use of ultrasonics in machining was first proposed by L. Balamuth in 1945. By 1954, the machine tools, using the ultrasonic principle, had been designed and constructed. 4 (1964): 167-173. The higher the cutting speed, the larger is the TWCR. Ultrasonic machining, also known as ultrasonic impact grinding, is a machining operation in which a vibrating tool oscillating at ultrasonic frequencies is used to remove material from the workpiece, aided by an abrasive slurry that flows freely between the workpiece and the tool. The basic structure of a general rotary ultrasonic machining system (RUMS) is shown in Figure 2. Practical and experimental studies have shown that rotary ultrasonic machining (RUM) is a suitable method because it has excellent material removal efficiency and good machining quality for hard and brittle materials. “Parametric optimization of ultrasonic machining process using gravitational search and fireworks algorithms.” Ain Shams Engineering Journal 6.1 (2015): 315-331.
