Dr. Melkote’s research addresses both basic and applied problems in the areas of precision machining, micromachining and part fixturing/handling.

His research in precision machining is focused on the investigation of surface generation mechanisms in processes such as hard turning, grinding, etc. In particular, it is aimed at understanding the role of process variables and material properties on the resulting surface topography, mechanical properties and microstructure and functional properties through experiments and modeling.

His work in micromachining is focused on developing models to accurately predict the mechanics of mechanical micro-cutting processes such as micro-grooving, micro-milling etc. He is also working to develop novel hybrid micromachining processes for creating complex three-dimensional micro scale features in difficult-to-machine materials. Ongoing work concerns the development of a laser-assisted mechanical micromachining process for fabricating hard metal and ceramic micro molds.

His work in part fixturing and handling is aimed at developing a mathematical approach to the design, analysis and optimization of mechanical fixturing/automated handling devices used in manufacturing and assembly. Such devices include complex fixtures used in machining and robotic grasping devices used in handling of thin flexible materials. Ongoing work includes the development of a model-based approach to analyze and optimize the stresses induced in automated handling of thin crystalline silicon wafers used in the manufacture of photovoltaic devices.
