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.

COURSE INSTRUCTOR
Ajay M Sidpara is a faculty in Mechanical Engineering Department at IIT
Kharagpur. His research interests are on surface finishing at nano scale and
micro machining for different applications such as optics, biomedical, micro
fluidics, etc. He has extensively worked on development of different tooling
for nanofinishing and micro machining and improvement of process efficiency
using different strategies. He has published 20 journal papers, 10
book chapters, and 21 conference papers related to nanofinishing and micro
machining. 2 patents are filed related to development of tool and process for
nanofinishing of complex surfaces. He has received funding of more
than 55 lakhs from SERB, BRNS and GE Power India. He has received
Gandhian Young Technological Innovation Award 2013, Young Engineers Award 2015
from IE (India), and CSR innovation award from GE Power India Limited
(erstwhile ALSTOM India Limited). He is a reviewer of more than 20
international journals and also delivered around 20 invited talks in the
institutes, and research labs.
