in ultrasonic machining, the tool moves

(Ans:d) d. none of these d. 14,000°C In machining operations like drilling, grinding, profiling and milling operations on all materials both conducting and non-conducting. d.

The material to be processed will affect the selection of the machining process. 6,000°C – Machining ceramics, carbides, glass, precious stones, and hardened steels, – Create microelectromechanical system components such as micro-structured glass wafers, – Manufacture parts with high precision and tolerance. Unlike other manufacturing techniques, the ultrasonic machining process has unique benefits. Ultrasonic machining is a contemporary manufacturing method usually employed for processing materials with higher hardness/brittleness such as quartz, semiconductor materials, ceramics etc. As a result of the compact design, the UTS2 can easily be integrated into any commercially available precision and ultra-precision machine. The Impact force arising out of the vibration of the tool end and the flow of abrasive slurry causing thousand of microscopic grains to … The ultrasonic generator converts the power frequency AC power into an ultrasonic frequency oscillation with a certain power output. Ultrasonic refers to waves of high frequency above the audible range of 20 kHz. As the tool vibrates it is pressed on the work surface with light force and allowing the abrasive slurry to flow through between tool-workpiece interface. It has five main components in its working. Some light oil like transformer oil or kerosene oil is used as dielectric. Ultrasonic Machining PPT with PDF Seminar Report: Ultrasonic machining is a mechanical material removal process that uses formed tools, vibration of high frequency and abrasive slurry mix.It works on a frequency of more than 20000 Hz. The tool is usually made from materials such as soft steels and nickel. In ultrasonic machining, the tool moves vertically or orthogonal to the surface of the part and fluctuate at the ultrasonic frequencies, the vibrations generated by the tool will project micro-sized abrasive particles to the part at a high speed, the particles mix with water or other liquids to form a slurry, which flowing between tool and workpiece, helps to grind away material from the surface of the piece. (Ans:c) a machining unit for shaping various solid materials. })(jQuery); Junying Metal Manufacturing has developed high-level manufacturing technique in In ultrasonic machining, a tool of desired shape vibrates at an ultra-sonic frequency (19 - 25 kHz) with an amplitude of around 15 - 50 m over the workpiece. As the tool vibrates, it makes abrasive particle to vibrate at this high frequency. A distinction is made between all-purpose and specialized ultrasonic machine tools. D. Stainless steel. The positive ions moves towards the tool (cathode) and negative ions move towards the workpiece. In this article, let’s take an overview of the ultrasonic machining process, covering its working principle, tools, advantages, disadvantages, and application. a. Burr free The tool oscillates with small amplitude of … The metal removal takes place due to erosion They get scattered Ultrasonic Machining . 9 In this idealized model, a cutting tool moves to the left along the workpiece at a constant velocity V, and a depth of cut to. There is no heat generation in the ultrasonic machining process, so the workpiece will not deform and the physical properties of the part will remain uniform. – Idea choice for ceramic matrix composites, glass, quartz, diamonds, PCD, etc. 2. c. electrolyte B. c. 10,000°C Now customize the name of a clipboard to store your clips. In ultrasonic machining, the tool moves vertically or orthogonal to the surface of the part and fluctuate at the ultrasonic frequencies, the vibrations generated by the tool will project micro-sized abrasive particles to the part at a high speed, the particles mix with water or other liquids to form a slurry, which flowing between tool and workpiece, helps to grind away material from the surface of the piece. Match List-I (Machining process) with List-II (Associated medium) and select the correct answer using the codes … 2. (Ans:c) By 1954, the machine tools, using the ultrasonic principle, had been designed and constructed. Principle of Ultrasonic Machining • During one strike, the tool moves down from its most upper remote position with a starting speed at zero, then it speeds up to finally reach the maximum speed at the mean position. 1. c. i,ii & iii With a number of manufacturing methods, manufacturers often want to find the best way for the specific project. The particles used in the abrasive fluid are usually boron carbide or silicon carbide as they are rigid than others. production fields of machining. Machining glass, ceramic, tungsten and other hard carbide, gemstones such as synthetic ruby. Ultrasonic machining is a method of grinding that uses an abrasive liquid rather than direct tool contact. a. vacuum chamber A. Not for hard metals Using abrasive slurry between the tool and work. 2.
