Which one of the following statements is TRUE for the ultrasonic machi...
Ultrasonic machining (USM) is a non-traditional machining process that utilizes the principle of ultrasonic vibrations to remove material from the workpiece. The process involves the use of a vibrating tool, which is usually made of a hard material such as tungsten carbide or diamond, and a slurry comprising abrasive particles and water.
Explanation:
1. Ultrasonic vibrations: The tool in USM vibrates at ultrasonic frequency, which typically ranges from 20 kHz to 100 kHz. These high-frequency vibrations are generated by a magnetostrictive transducer, which converts electrical energy into mechanical vibrations.
2. Magnetostrictive transducer: USM employs a magnetostrictive transducer to generate ultrasonic vibrations. This transducer consists of a magnetostrictive material, such as nickel or cobalt, which undergoes dimensional changes when subjected to a magnetic field. This produces the required ultrasonic vibrations in the tool.
3. Machining ductile materials: USM is not particularly suitable for machining ductile materials. Ductile materials have the ability to deform plastically under stress, which makes them difficult to machine using USM. This process is more effective for machining brittle materials, such as ceramics, glass, and certain composites.
4. Slurry composition: USM often uses a slurry comprising abrasive particles and water. The abrasive particles, such as silicon carbide or diamond grit, act as cutting tools and assist in material removal. The water in the slurry helps in cooling the workpiece and flushing away the debris generated during machining.
Conclusion:
From the given options, the statement that is true for the ultrasonic machining (USM) process is option 'D'. USM often uses a slurry comprising abrasive particles and water. This slurry assists in material removal, cooling, and debris removal during the machining process.
