a) 10 L/min The vibration of the tool fixed to the end of the horn is ultrasonically vibrated by the amplitude amplifying rod (horn), forcing the abrasive suspension to continuously hit at high speed and polishing t… An electronic oscillator in the control unit produces an alternating current oscillating at a high frequency, usually between 18 and 40 kHz in the ultrasonic range. A. (mech), mnnit, allahabad (formerly m.n.r.e.c., allahabad), 1987 m.tech. True. Ultrasonic machining is changing the manufacturing industries with its superlative performance. View Answer, 7. EQUIPMENT • Ultrasonic Machining consists of : 1.High Power sine wave generator. In USM, tool tips must have low resistance and fatigue strength. Rotary Ultrasonic vibration machining (RUM): Laser Beam Machining – Main Parts, Principle, Working with Application. During ultrasonic machining, the metal removal is achieved by (a) high frequency eddy currents (b) high frequency sound waves (c) hammering action of abrasive particles (d) rubbing action between tool and workpiece 2. d) All of the mentioned A typical UT inspection system … This machining process is usually used to machine brittle materials and materials that have high hardness. The grain sizes of the abrasive material are typically ranges from 100 to 1000. 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. Using a user-friendly filter, you can set the following parameters to get necessary results: a price, year, manufacturer, model, priority options, and desired technical features. An ultrasonically vibrating mill consists of two major components, an electroacoustic transducer and a sonotrode, attached to an electronic control unit with a cable. The ultrasonic machining (USM) process consists of two methods, namely, ultrasonic impact grinding and rotary USM. Inaudible sounds (Ultrasonic frequency) can used to attack these devices by exploiting the above vulnerability. Why Choose CNC Aluminum Over Other Metals For Prototyping? Answer: d Explanation: In machining system of USM, the above mentioned components have to be present. It is very precise machining method and used in the creation of micro-electrochemical system components like micro-structured glass wafers. The simplicity of the Abrasive slurry is not used in this type of machine for material removal. All Rights Reserved. What Companies In The Oil Industry Can Do To Enhance Worker Safety? a) True Ultrasonic Testing (UT) uses high frequency sound energy to conduct examinations and make measurements. By 1954, the machine tools, using the ultrasonic principle, had been designed and constructed. b) Electrical energy Slurry to machining zone Return slurry Fig. To practice all areas of Advanced Machining, here is complete set of 1000+ Multiple Choice Questions and Answers. When the tool presses against the w/p, the slurry containing abrasive particle chips off the materials from the surface. Vibration assisted machining utilized vibration ranging from low to high frequency with small amplitude. All the operations done with the ultrasonic machining method are cost effective and best in results. And this is because, no heat is generated by the sonotrode against the w/p. When this vibrating sonotrode strikes the surface of the w/p, it removes the material form it. c) 1 – 10 µm 6.6.1 Introduction. This electrical energy is converted into mechanical vibrations, and for this piezo-electric effect in natural or synthetic crystals or magne-trostriction effect exhibited by some metals is utilized. This material, called slurry, is a mixture of a free-flowing liquid and one or more types of solid abrasive. What is the value of the amplitude obtained when we use mechanical amplifier? b) 10 – 40 µm View Answer, 5. 18 kHz to 40 kHz) is used to generate mechanical vibration of low amplitude and high frequency. (A) USM employs an abrasive slurry. What is the value of the amplitude obtained without mechanical amplifier? This leads indentation of abrasive particle to brittle work piece and removes metal from the contact surface. Ultrasonic vibration machining can be used only to machine materials that have hardness value atleast 45 HRC (HRC: Rockwell Scale to measure hardness of a material). The wear of sonotrode tip occurs more quickly. 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 View Answer, 3. Period B. PRF C. Wavelength D. Density. 11. 1.2 Machining unit for Ultrasonic machining :- Fig 1.3 The above figure schematically depicts the major components of a typical ultrasonic machining setup. Answer: d Explanation: In machining system of USM, the above mentioned components have to be present. The main reason why this machining process is used in the manufacturing area is because it evolves less heat in the process. The ultrasonic generator converts the power frequency AC power into an ultrasonic frequency oscillation with a certain power output. The machining system of USM contains which of the following components? USM is used in precision machining of hard and brittle material. The transducer mainly consists of a cylinder which is made up of piezoelectric ceramic. The key to an ultrasonic machining process is the abrasive liquid. The frequency produced is usually in between 18 kHz to 40 kHz in ultrasonic range. Ultrasonic welding, for thermoplastic injection moulded components, is a process that uses mechanical vibrations above the audible range. Ultrasonic inspection can be used for flaw detection/evaluation, dimensional measurements, material characterization, and more. View Answer, 2. The transducer converts this alternating current into mechanical vibration and transmits this mechanical vibration to the sonotrode attached to it. 2. Advantages of USM• Machining any materials regardless of their conductivity• USM apply to machining semi-conductor such as silicon, germanium etc.• USM is suitable to precise machining brittle material.• USM does not produce electric, thermal, chemical abnormal surface.• Can drill circular or non-circular holes in very hard materials• Less stress because of its non-thermal characteristics It consists of a generator for supplying a high frequency electric current, a transducer to convert this into a mechanical motion in the form of a high frequency vibration, a holder … The machining system of USM contains which of the following components? It also provides schematic representations of the components used in rotary USM and ultrasonic impact grinding. The slurry flows in between the tool and workpiece and helps in the removal of the material from the surface. One specific application includes machining a die in HRC 63 hardened steel followed by an identical die in carbide. Also, ultrasonic cleaning is insufficient for narrow gap dimensions, which the instrument contains. Transducer: The transducer mainly consists of a cylinder which is made up of piezoelectric ceramic. higher number of grain) results in smooth surface finishes. • The transducer, which generates the ultrasonic vibration • The horn or concentrator, which mechanically amplifies the vibration to the required amplitude of 15 – 50 μm and accommodates the tool at its tip. advertisement. Participate in the Sanfoundry Certification contest to get free Certificate of Merit. Ultrasonic machine generates high frequency vibrating wave of frequency about 20000 to 30000 Hz and amplitude about 25-50 micron. d) None of the mentioned a) 0.0001 – 0.001 µm To simplify medical equipment selection, you can use our convenient search system to find the right product at a reasonable cost.
