Dr. Stephen P. Radzevich is a Professor of Mechanical Engineering, and a Professor of Manufacturing Engineering. He received his M.Sc. in 1976, Ph.D. in 1982, and Dr.(Eng)Sc. In 1991, all in mechanical engineering. Dr. Radzevich has extensive industrial experience in gear design and manufacture. He has developed numerous software packages dealing with computer-aided design (CAD) and computer-aided machining (CAM) of precise gear finishing for a variety of industrial sponsors. His main research interest is the Kinematic Geometry of Part Surface Generation, particularly with a particular focus on precision gear design, high-power-density gear trains, torque share in multi-flow gear trains, design of special purpose gear cutting/finishing tools, and design and machine (finish) of precision gears for low-noise and noiseless transmissions of cars, light trucks and so on. Dr. Radzevich has spent over 40 years developing software, hardware and other processes for gear design and optimization. Besides his work for industry, he trains engineering students at universities and gear engineers in companies. He has authored and coauthored over 30 monographs, handbooks, and textbooks. The monographs “Generation of Surfaces” (RASTAN, 2001), “Kinematic Geometry of Surface Machining” (CRC Press, 2007, 2nd Edition 2014), “CAD/CAM of Sculptured Surfaces on Multi-Axis NC Machine: The DG/K-Based Approach” (M&C Publishers, 2008), “Gear Cutting Tools: Fundamentals of Design and Computation” (CRC Press, 2010), “Precision Gear Shaving” (Nova Science Publishers, 2010), “Dudley’s Handbook of Practical Gear Design and Manufacture” (CRC Press, 2012), “Geometry of Surfaces: A Practical Guide for Mechanical Engineers” (Willey, 2013) are among his the recently published volumes. He also authored and coauthored over 300 scientific papers, and holds over 250 patents on inventions in the field (USA, Japan, Russia, Europe, Canada, South Korea, Mexico, and others).
