Research highlights

Presently, we are working in two major research areas of manufacturing engineering and those are as follows: 

1.  Ultra-precision Finishing 

2.  Additive Manufacturing

                  2.1. Laser-based additive manufacturing 

                  2.2. Thermal spray coating 

Ultra-precision finishing: 

With the rapid advancement of nanotechnology, the demand for nano-finished components having sub-micron level form accuracy and without any appreciable surface or sub-surface damages (SSD) has been increasing expeditiously. Ultra-precision finishing processes have the ability to meet those stringent requirements. We are actively working on a few well-known ultra-precision finishing processes such as Magnetorheological Finishing (MRF), Shape Adaptive Grinding (SAG), and Elastic Emission Machining (EEM). In addition to that, I have also an interest in the Diamond turning process.

Additive Manufacturing:

Laser Directed Energy Deposition (LDED) is a promising additive manufacturing technique that has a huge potential in remanufacturing and restoration of high-value dies/molds and aerospace components. LDED offers several advantages such as high deposition rate, minimal heat input, low heat affected zone (HAZ), and less distortion. Thermal Spray Coating is also widely used to deposit metallic or non-metallic thick coatings on the substrates. To meet the stringent requirement of machine components, different thermal spray coatings have been developed. We are actively working in both the fields (i.e., LDED and Thermal spray coating).
