The present invention provides as improved ultrasonic abrasive flow machining for improved finishing of surface. The process is developed to enhance the capability of the traditional abrasive flow machining process by addition of high frequency of for ex. 5kHz-20kHz vibration to the work piece whereby the effectiveness of the abrasives (cutting edges) increases owing to better contact conditions at the tool-work interface. The instant invention comprises of a piezo device so as to impart the uniaxial vibratory assistance to the work piece through a mechanical coupling device inside a specially designed multipurpose tooling. The amplitude of vibration is kept within 10µm. The new process records enhancements in surface finish and material removal at about 787% and 876% respectively while compared to the convectional AFM process (while machining Inconel 718). Further said process is simple, safe and easy to adopt in terms of operation, control and add-on requirements. It can be used for the jobs irrespective of their shape and internal geometry.

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.
