Brief Introduction to the Laboratory

Micro fabrication is the primary objective of the lab. In addition, micro machining: Simulation and experimental characterization of hard and difficult to cut metals are the common jobs. The lab is situated at the central workshop of Indian Institute of Technology (ISM) Dhanbad, India (formerly Indian School of Mines Dhanbad). At present the lab has 10 members including students (PhD and MTech)
