D.C. supply is usually obtained from generators driven by electric motor or if no electricity is available then the diesel engine can be used. c) <1000 mm2 When very frequency vibrations are applied on to the tool, the tool is vibrating at a very high frequency. Which results in faster machining, however, it is seldom used because of … Engraving; Trepaning and coining; Threading; Slicing and broaching hard materials. a) Drilling A variation of this technique is ultrasonic drilling, which makes use of pneumatic vibrations at ultrasonic… Grinding the brittle materials.4. a) conventional milling. In this article, let’s take an overview of the ultrasonic machining process, covering its working principle, tools, advantages, disadvantages, and application. Ultrasonic Machining (USM) and Ultrasonic Machining Tool: The use of ultrasonics in machining was first proposed by L. Balamuth in 1945. These micromachining processes mainly use mechanical forces to remove materials. This process is best suited for brittle materials.4. Ultrasonic Machining Process description. Ultrasonic Machining Animation Ultrasonic machining is a loose abrasive machining process in which the mirror image of a shaped tool can be created in hard, brittle materials. d) All of the mentioned Now this process is used in many industries to remove metal due to its lower cost, no heat generation, and effective machining. a) True b) False ... here is complete set of 1000+ Multiple Choice Questions and Answers.
