Dr. Stephen P. Radzevich is a Professor of Mechanical Engineering, and a Professor of Manufacturing Engineering. He received the M.Sc. (1976), the Ph.D. (1982), and the Dr.(Eng)Sc. (1991) - all in mechanical engineering. Dr. Radzevich has extensive industrial experience in gear design and manufacture. He has developed numerous software packages dealing with CAD and CAM of precise gear finishing for a variety of industrial sponsors. His main research interest is Kinematic Geometry of Surface Generation, particularly with the focus on (a) precision gear design, (b) high power density gear trains, (c) torque share in multi-flow gear trains, (d) design of special purpose gear cutting/finishing tools, (e) design and machining (finishing) of precision gears for low-noise/noiseless transmissions of cars, light trucks etc. Dr. Radzevich has spent about 40 years developing software, hardware and other processes for gear design an optimization. Besides his work for industry, he trains engineering students at universities and gear engineers in companies. He authored and co-authored over 30 monographs, handbooks, and textbooks. The monographs entitled "Generation of Surfaces" (2001), "Kinematic Geometry of Surface Machining" (CRC Press, 2008), "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, 2nd edition 2017), "Precision Gear Shaving" (Nova Science Publishers, 2010), "Dudley's Handbook of Practical Gear Design and Manufacture" (CRC Press, 2012, 2nd edition 2016), "Theory of Gearing: Kinematics, Geometry, and Synthesis" (CRC Press, 2012, 2nd edition 2018), "Geometry of Surfaces: A Practical Guide for Mechanical Engineers" (2013) are among the recently published volumes. He also authored and co-authored about 350 scientific papers and holds over 250 patents on inventions in the field, both, USA patents and International.

Expands explanation of reversibly-enveloping surfaces (RES), proposing a qualitative (analytical) approach of RES in this new edition

Provides an analytical description of part surfaces to be machined and elucidates the principal difference between differential geometry of surfaces and the engineering of part surfaces

Focuses the readers' attention on circular diagrams, simple but powerful analytic constructs, erected at a point of a part surface

Illustrates a practical means of mapping of one part surface onto another part surface, with emphasis on a newly developed R-Mapping of part surfaces
