The present invention relates to a device and its method for rotary disc grinding assisted electrochemical discharge machining process with dual with adaptive feeding feature. The device comprises an abrasive coated disc rotating by a DC motor along with a rotation controlling system and dual adaptive work material feeding system (simultaneously in two directions). The device provides synchronized feeding of work material in two directions as per the change in material removal during the machining. This is essential because in general in ECDM process the formation of sludge during the machining results in varying material removal, also in MMCs the material removal changes due multiple constituents are available. The said device and method can be used to perform multiple machining operations such as cutting, slitting and slotting of metal and non-metals of any geometrical shaped solid component using electrochemical based machining process. In an embodiment, the device utilizes micro and macro machining of metals and non-metals using electrochemical based process having adaptive feeding system.

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.
