The design of this site was heavily, heavily inspired by, http://www.nitc.ac.in/dept/me/jagadeesha/mev303/Chapter_3_USM.pdf, https://www.sciencedirect.com/science/article/pii/S0890695597000369, Electron Beam Welding: Definition, Construction, Working, Applications, Advantages, and Disadvantages [Notes with PDF], Extrusion Process: Definition, Working Principle, Types, Applications, Advantages, and Disadvantages [Notes with PDF], Die Casting: Definition, Process, Types, Defects and Remedies, Applications, Advantages, Disadvantages [With PDF]. Ultrasonic machining doesn’t require heating workpieces. Therefore the tool is made of tough, strong and ductile materials like steel, stainless steel or HSS (High stainless steel), Mild Steel, etc. a) Tool As the machines perform several techniques like: It consists of an electromechanical transducer connected to the AC supply. Now this process is used in many industries to remove metal due to its lower cost, no heat generation, and effective machining. a) Drilling The major function of this process is that the brittle materials […], In this article, I'll show you everything you need to know about the Die Casting Process. b) Work piece a) <100 mm2 This is essential. Working Principle of ultrasonic Machining: Let us know if you liked the post. a) 0.01 – 0.10 cm/min generally above 16 kHz. Aluminum oxide, Silicon carbide, Boron carbide are used as an abrasive particle in this slurry. 1. 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. 6 7. d) 7 μm When very frequency vibrations are applied on to the tool, the tool is vibrating at a very high frequency. View Answer, 5. Velocity transformer which holds the tool firmly.
