Research Interests

Manufacturing processes are processes, which transform raw materials into goods. The main manufacturing processes include turning, milling, drilling, grinding, lapping, and polishing. The main focus of my research is grinding, lapping, polishing, superfinishing, honing, turning. Specifically, I focus on the topics of Grinding of Ceramics with Diamond Wheels, Fundamentals of Lapping and Polishing, Superfinishing of Bearing Rings, Acoustic Emission Investigations of Abrasive Processes, Polycrystalline Diamond Turing of Granite, and Laser Assisted Grinding of Brittle Materials.

The investigated processes are mainly finishing processes which require accuracy at micron and nanometer level. This research will increase the competitiveness of the American industry, especially aerospace, automotive and electronic industries. At the same time, the aim of this research is to manufacture products more cheaply, more quickly, and with better quality. The products resulting from this research include automotive parts (metal and ceramic parts), bearings, jet engine components, and silicon wafers for computer chips to name a few.

Tribology is the science of friction, wear, and lubrication. Everything around us which has a relative motion experiences friction and wear, and lubrication is the solution to decrease the friction and wear.

Every year billions of dollars spent in the US because friction and wear result in the loss of energy and materials. Many industrial and natural processes can be explained, understood and predicted by the aid of tribology knowledge.

The main topics in my tribological research are:

  • Tribological Investigation of Abrasive Processes;
  • Minimum Lubrication in Metal Cutting;
  • Investigation of Friction and Wear Mechanisms;
  • Molecular Dynamics Simulation of Friction and Wear.

To understand tribological phenomena it is necessary to study them at nanometer and angstrom level. Only the interaction between molecules and atoms will give us the real mechanism of tribological processes.

The impact of this research on society will be immense. In Europe, many countries are heavily investing in tribology in order to decrease the losses in energy. After about 20-25 years this field is reemerging as a major area of investigation in the US.

Combined these two presented fields, manufacturing and tribology, will advance the science with immediately application in industry, providing the society with better and chipper products and will improve the competitiveness of the US products.
