    Basic Information

Technology developed: A device for pressurized multiphase flow during electro-chemical discharge machining process (TP19769888208)
Category: Product(Hardware/Material/Software)
Details of Inventor(s):
Inventor Institution/Organization/Company Department Designation
Dr. Akshay Dvivedi Indian Institute of Techonology Roorkee Department of Mechanical and Industrial Engineerin Associate Professor
Dr. Rajendra Kumar Arya Indian Institute of Techonology Roorkee Department of Mechanical and Industrial Engineerin Research Scholar
Technical Application Area: Mechanical Engineering
If 'Other', please specify:
Mechanical Engineering
Please give more details of new technical application area:
Electrochemical discharge machining (ECDM) process is capable to fabricate micro holes on different materials, mostly on non-conductive materials. However, the high aspect-ratio of drilled micro holes is limited due to absence of electrolyte and gathering of machined by-products like sludge, molten salt and debris inside the machining zone, at higher depth. The developed device (i.e., Pressurized Multiphase Flow device) enables the drilling of high aspect-ratio micro holes on various difficult-to-machine materials by using it with ECDM process. This device provides fresh working electrolyte flow into the machining zone and removal of machined by-products from the machining zone. Incorporation of innovative device with ECDM process can be utilized for drilling of micro holes on other difficult to machine materials. The technical application area may be fabrication of MEMS and microfluidic devices.
Organization(s):
Indian Institute of Technology (IIT) Roorkee

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.
