  Subject: Advanced Manufacturing Process Unit 2: Part 1: Ultrasonic Machining Definition of USM:  Ultrasonic machining (USM) is a machining or material removal process in which material is removed from the work- piece by brittle fracture caused by impact of abrasive grains due to tool vibration at very high frequency. Construction of USM setup:  A typical USM setup consists of following essential elements: a. Power Supply (AC) b. Tool Feed Mechanism c. Abrasive Slurry d. Abrasive slurry supply & recirculation system e. Working Tank or, Basin Working Principle of USM • At first, the workpiece is assembled in the fixture inside the working tank & the tool is brought closer to it. • Then the power supply is switched on & the tool starts to vibrate. • An abrasive gun or nozzle supplies an abrasive slurry in the gap between the tool & the workpiece at a definite pressure. • As the tool vibrates it produces impact force upon the abrasive particles & these p...

Subject: Advanced Manufacturing Process Unit 1: Introduction to Non-traditional Machining Processes Machining Process Machining is defined by the process of removing excess material from the work piece to obtain the desired shape and size of a final product. Classification of Machining Process Depending upon the type of machine tools that are used for machining, machining processes can be classified as follows: 1. Traditional or, Conventional Machining Example- Turning, Milling, Drilling, Broaching etc. 2. Non-Traditional or, Unconventional Machining Example- WJM, AJM, USM, CHM, ECM, EDM, EBM, LBM, PAM etc. Traditional Machining Process In traditional or conventional machining processes material removal is done by relative motion between the tool and work piece in the form of chips by shearing action.  Example- Turning, Milling, Drilling, Shaping, Planning etc. Non-Traditional or Unconventional Machining Process In non-traditional machining process the metal removal is done by vari...
