Dr. Afzaal Ahmed is an Assistant Professor in Department of Mechanical Engineering, IIT Palakkad. His research interests broadly centers on the non-coventional machining, hybrid machining, deep hole drilling, laser based surface alloying and metal additive manufacturing (AM). 

Dr. Ahmed has been involved in multiple projects funded by Agency of Science Technology and Research (A*Star), Singapore and Singapore Institute of Manufacturing Technology (SIMTech) that focussed on development and implementation of hybrid processing techniques for Large Format Machining of Nickel based superalloys. During the PhD, he developed a novel hybrid electrical discharge and arc machining process (HEDAM) for the efficient and ultrafast machining of difficult-to-cut superalloys such as Inconel 718, Ti-6Al-4V etc. His research expertise also include evaluation of machined surfaces via roughness, microhardness, microstructure with various microscopic and spectroscopic techniques like SEM, EDS, XRD, AFM, TEM and XPS.
