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...

  Subject: Manufacturing Process I Unit 2: Metal Forming Processes Unit 2 Part 3: Forging Process Forging It is a forming process in which the raw material is heated to plastic state & it is deformed between a pair of dies by application of pressure to transform it into desired shape permanently. Note Forging is generally a hot working Process. Pressure applied is forging process by - Hand Hammer & Power Hammer. Types of Forging Depending upon the means of application of pressure forging process can be of two types, as – Hand Forging  Machine Forging Machine forging can further be classified into following two types:  Drop Forging &  Press Forging. Hand Forging It is a forging process in which the raw material is heated in an open fire and shaped gradually by hammering with manual hammer using basic tools, is called hand forging or, black smith forging. The hand forging process is useful for small scale productions. In this process, products of simple sha...

Subject: Manufacturing Process I Unit 2: Metal Forming Processes Unit 2 Part 2: Rolling Process Definition of Rolling It is a forming process in which the raw material is heated to plastic state & it is compressed between two rolls of equal size and the raw material is deformed under the combined action of compression and shear such that the cross-section area is reduced at the expense of increasing length. Note Rolling is generally a Hot Working Process. The raw material used in rolling is called INGOTS which are made by casting process. After rolling the ingots, they become BLOOM . Blooms are bars of square cross section. Blooms are further rolled into BILLETS. Billets are shorter in length. Types of Rolling Depending upon the working temperature, Rolling can be of two types, like Hot & Cold Rolling. Hot Rolling When the working temperature in a particular rolling process is above the recrystallisation temperature of the work metal, then it is called hot rolling. Cold Rollin...
