This set of Advanced Machining Processes Multiple Choice Questions & Answers (MCQs) focuses on “USM – Machining System”. What is Drilling Machine and How It Works? Ultrasonic assisted machining is a machining operation based on the intermittent cutting of material which is obtained through vibrations generated by an ultrasonic system. The main reason why this machining process is used in the manufacturing area is because it evolves less heat in the process. Glass, carbides, ceramics, precious stones and hardened steels are the most common materials machined by USM. Ultrasonic machining—on the other hand—can machine carbide directly in one set-up with minimal tool wear and eliminates the need to produce electrodes. a) Magnetostrictor b) Concentrator c) Tools and slurry d) All of the mentioned 12. At what rate slurry is pumped through nozzle in USM? A basic ultrasound machine has the following parts: Transducer probe - probe that sends and receives the sound waves Central processing unit (CPU) - computer that does all of the calculations and contains the electrical power supplies for itself and the transducer probe The abrasive gain particles in the slurry helps in the removal of the material form the surface of the w/p. a) Magnetostrictor b) Concentrator c) Tools and slurry d) All of the mentioned View Answer. 2. Ultrasonic inspection can be used for flaw detection/evaluation, dimensional measurements, material characterization, and more. Ultrasonic welding, for thermoplastic injection moulded components, is a process that uses mechanical vibrations above the audible range. This is essential. USM is used in precision machining of hard and brittle material. False. Your email address will not be published. 3.Tool Holder. The sonotrode vibrates at low amplitude and high frequency and removes material from the w/p by abrasion where it contacts it. Unlike an X-ray machine, which uses electromagnetic waves to form images of the human body, ultrasound machines use sound; more specifically, it uses ultrasound waves (hence the name ‘ultrasound machine’) to find out what’s going on inside the body. Ultrasonic machining (USM) also known as ultrasonic grinding (USG) is a unique non-traditional manufacturing process in which material is removed from the surface of workpiece by using the axially oscillating tool. This article lists the major ultrasonic components that are similar to both rotary USM and ultrasonic impact grinding. What is Electrochemical Grinding and How it Works? It is made of low carbon steel. The transducer operates by magnetron striction. View Answer, 7. The device for converting any type of energy into ultrasonic waves is the ultrasonic transducer. The maximum value per part was specified to be 5 CFU. Ultrasonic components: the right solutions for every need All our products are designed and developed in-house after careful research and experimentation. View Answer, 4. How Electron Beam Machining Process Works? The ultrasonic generator is responsible for converting the incoming power frequency from 60hz to the frequency required by the ultrasonic transducers which are installed in the system, typically 25kHz, 40kHz or 80kHz. The function of various parts are described below. b) Electrical energy EATON, Ohio – November 24, 2020 – Bullen Ultrasonics is Dayton Business Journal’s 2020 Business of the Year. - Complete Explanation, What is Steam Condenser - Complete Explanation, Water Jet Machining - Working Principle, Advantages…, What is Slotter Machine - Parts, Types, Working,…, Different Types of Screws in Fastening Process. a) 0.0001 – 0.001 µm It converts electrical energy into mechanical vibration. The wear of sonotrode tip occurs more quickly. Ultrasonic machine generates high frequency vibrating wave of frequency about 20000 to 30000 Hz and amplitude about 25-50 micron. There is no distortion produced in the worked material.
