Introduction To Mechanical Micro Machining

The emergence of miniature and micro products / components has increased the demand of the production of micro components with feature size from a few millimeters to tens of micrometers. Mechanical micro machining is one of the key technologies to enable the realization of high accuracy complex micro products made from a variety of engineering materials. Mechanical micro machining is capable to machine metals, polymers, and ceramics in very less time as compared to lithographic processes and other micro machining processes such as EDM, ECM, LBM, etc. As a result, it has found strong base in a wide array of practical applications.Though the machine for micro cuttings are kinematically similar to conventional machines, there are many differences in terms of process mechanics, machine components, etc. Hence, understanding of machining at micro scale is very important to process any material to the desired dimensions.INTENDED AUDIENCE : Mechanical,Manufacturing,Production.PRE - REQUISITES :Conventional machining processes (lathe, milling, drilling, etc.)INDUSTRY SUPPORT : Research institutes: Bhabha Atomic Research Center (BARC), Mumbai; Central Mechanical Engineering Research Institute (CMERI), Durgapur; Central Manufacturing Technology Institute (CMTI), Bangalore
