Direct Digital Simulation for gears
by Prof. Veniamin I. Goldfarb and Dr. Stepan V. Lunin

$69.95US
This book is a valuable contribution to the development of the advanced digital technology in application for gear drives. The book presents a unique approach for solving complex gear design and manufacturing problems. The Volume 1 covers variety of applications of the Direct Digital Simulation method with numerous graphic examples and software samples. The book if targeted on gear engineers, students and advanced gear professionals. The high-resolution 3-dimentional graphic simulations will help the beginners to learn this complicated area of mechanics. The software samples will be useful for every day work of engineers and for advanced gear software developers. With this book the authors are responding to the numerous inquiries for publishing of practical learning materials about the new numerical method for gear development.
Note from Dr. Lunin:
I sincerely appreciate the idea of Prof. Goldfarb to publish our work. Prof. Goldfarb and I have been independently developing this new digital approach to the
gear theory in early 80’s. My contribution to this book consists of detailed description of the underlying engineering principals advertised

The library of selected AutoLISP and OpenGRIP programs can significantly simplify reading Direct Digital Simulation for Gears and understanding how the DDS method works. The software library is a good start for developing of your own DDS programs for practical use in gear design and gear manufacturing. Most of 3-dimentional models in the book are generated by using the programs from the library.
The Library of AutoLISP and Open GRIP DDS programs is available for download. AutoCAD is required to run the AutoLISP programs. Unigraphics is required to run the Open GRIP program.
The Library includes programs for:
Crown face gear. AutoLISP
Cut rack from spline. AutoLISP
Cut screw or worm. AutoLISP
Cut spline from rack. AutoLISP
Draw involute. AutoLISP
Rolling Enveloping. AutoLISP
Gear cutting by generation method. Can be used for any gear. Open GRIP
