Question

Which energy type is used in ultrasonic machining (USM)

Answer 1

Answer:

Ultrasonic machining is a nontraditional process. In this process abrasives contained in the

slurry are driven against the work by a tool oscillating at low amplitude (25–100 microns)

and high frequency (15–30 kHz). Ultrasonic refers to waves of high frequency above the

audible range of 20 kHz. The ultrasonic machining was proposed by L Balamuth in 1945.

It was developed for finishing of electro spark machine parts. The USM process consists

of tool made of ductile and tough material. Tool oscillates with high frequency, and the

continuous abrasive slurry is fed between the tool and workpiece. The impact of the hard

abrasive particles fractures the workpiece thus removing the small particles from the

work surface.

Ultrasonic machining is different from the conventional grinding process. Table 2.1

gives the comparison between the two.

Answer 2

Mechanical energy is used in ultrasonic machining.

Explanation:

• In an ultrasound machine, the USM is a nonthermal and nonelectrical machine process. Which has a material a microstructure and physical properties.  

• The ultrasound has sound properties that are characterized by the movement of particles within the medium. It is distinguished by the vibrations of particles that are greater than 20,000 Hz.  

• The energy travels in waves form with particles being deformed and displaced. The types of energy include sheer, surface, and longitudinal waves. Common uses are in diagnostic imaging.
