Abstract:
The present invention relates an apparatus and a method for micromachining of soft polymeric materials under a controlled environment. Accordingly, a novel apparatus is designed for machining polymer workpiece comprising of an insulated chamber housing a tool and a workpiece, wherein said workpiece is held by a workpiece holding fixture and aligned with the tool. Further the apparatus includes a cryogenic supply unit for cooling said workpiece and said tool, wherein said supply unit carrying cryogenic liquid is connected to the chamber through a delivery tube, the delivery tube directs the cryogen liquid from the supply unit onto the workpiece and the tool. And a process controller integrated with a pressure regulator, a strip heater and a temperature sensor, enables said controller to measure, monitor and control the inside temperature of the chamber for cryogenic machining of polymers under controlled environment.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
