The Ultrasonic Machine consists of different parts as follows: To starts, the machining process power is required. Ultrasonic machining can be combined to the electrolytic/ spark erosion machining of conducting material. Ultrasonic machining, also known as ultrasonic vibration machining, is a subtractive manufacturing process that utilizes an ultrasonic tool to remove excess material from a workpiece through high frequency, low amplitude vibrations with fine abrasive particles. ATTENTION: Don't forget to share this stuff on your favorite social media platform, and be a part of #Spread_the_knowledge. Which of the following is a conventional process of machining? For making the object, the raw material is pushed into a die to provide it with the desired shape. Drilling the round holes of any shape.3. This process is best suited for brittle materials.4. It is used for:1. An abrasive gun is used to supply an abrasive slurry, which is a mixture of abrasive grain and the water in between tool-workpiece interface under a definite pressure. Ultrasonic Machining is mainly used to machine hard and brittle materials with low ductility. Ultrasonic Machining (USM) also called as ultrasonic vibration machining is a machining process in which material is removed from the surface of a part by low amplitude and high frequency vibration of a tool against surface of material in the presence of abrasive particles. When very frequency vibrations are applied on to the tool, the tool is vibrating at a very high frequency. Abstract.
