The present invention relates to a natural polymer abrasive media for the abrasive flow machining and a process for preparation thereof. The media comprising of 35-40% by weight of monoesters, 12-13% by wt. of Alkanes and 8-10% by wt. of Alkenes. It is thermally stable up to a minimum temperature of 71ºC, does not exhibit any rise in temperature while machining even up to a duration of 20 minutes, and does not show any tendency to settle up to a minimum of 1080 hours. The developed media is environment-friendly, bio-degradable, reusable and yields better performance as compared to available media materials. The developed media can be used as an alternative for existing media and can reduce the processing cost.

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.
