Current and Recent Projects

Machining and Grinding - Machining and grinding are material removal processes for producing parts of desired shape, size, accuracy, and surface integrity. Over $300 billion/year is expended in the U.S. for these operations (labor and overhead only, not including materials or equipment). As these processes are of technological and economic significance, fundamental understanding of these processes is critical for the advancement of these fields.

Diamond Coatings - Low pressure synthesis of diamond films and diamond crystals by chemical vapor deposition (CVD) and by combustion techniques has opened up new opportunities for this high-tech material. Diamond is the hardest known material. It also has very high thermal conductivity (2-5 times that of copper), corrosion and wear resistance. Diamond coatings or crystals can be used for a variety of manufacturing applications including wheels for grinding, cutting tools for machining, and dies for metal forming. These films can also be used for tribological (e.g. bearings for low friction and corrosion resistance), ultra precision machining, optical (e.g. IR windows) and semiconducting (e.g. heat sinks, P and N materials) applications.

Tribology - Tribology, the science and technology of interacting surfaces in relative motion, has evolved from the classical fields of friction, lubrication, and wear. It plays a pivotal role in manufacturing, particularly in materials processing such as metal forming and cutting. A basic understanding of the complex processes that occur at the interface between a tool or die and the work material (wear, adhesion, material transfer, and chemical interactions between the surfaces in relative motion) can contribute significantly towards reduction of wear of tools or dies and increase productivity.

Ultra Precision Machining - Single crystal diamond tools are used on specially designed machine tools for precision machining of metal mirrors and aspheric optics with surface roughness approaching a few nanometers r.m.s. Ceramics and glasses are now machined at very small depths of cut ("gentle" grinding) to minimize surface cracks. The mechanics of machining at such fine depths are not well understood. This is an area of great technological significance. Molecular dynamics (MD) simulation is used to study the chip formation process at fine depths of cut (nanometric cutting).

Non-Traditional Processing - Many advanced materials such as ceramics, composites, and other difficult-to-machine materials are being introduced for high performance applications. These materials have to be processed by such non-traditional processing techniques as electro-discharge machining (EDM), electrochemical maching (ECM), abrasive water jet cutting, laser processing, and plasma processing. A fundamental understanding of the mechanics of these processes, process capabilities, and limitations would be of great scienticfic and technolgical value.

Molecular Dynamics Simulations of Nanometric Cutting & Tribology - Molecular dynamics (MD) simulations can play a significant role in addressing a number of machining and tribological problems at the atomic scale. In fact, such data may not be obtained readily in any other way, theory or experiment. At OSU, we are addressing MD simulations of various workmaterials both metals and semiconductor materials, effect of crystal orientation and cutting direction, geometry of the tool, exit-failure, atomic scale friction, nanomechanical properties. We are also extending this work to MD/Monte Carlo (MC) simulations as well as parallel processing.

Thermal Aspects of Various Manufacturing Processes - Considerable amount of heat is generated in various manufacturing processes due to plastic deformation and friction. High temperatures in the cutting tool and/or steep temperature gradients in the workmaterial can limit the productivity in manufacturing due to rapid tool wear or objectionable metallurgical damage/residual stresses in the workmaterial. Thermal analysis of various manufacturing processes will enable us to address these issues and optimize the process parameters. At OSU we are addressing thermal aspects of various manufacturing processes including cutting, high-speed machining, polishing, grinding, welding, heat treatment, and tribological problems.
