for Automatic
Machines:
American Elsevier Publishing Company, tnc., New York, 1969; 231 pages, 57 illustrations, 31 diagrams and numerous numerical Tables. IN THE mechanization and automation of hitherto manually controlled operations increasing use is being made of m e c h a n i s m s fl)r the control of ~ o r k i n g parts involved in practical realization of technological processes. The drive towards higher machine ratings and improved e c o n o m y of operation results in the necessity for higher working speeds, and this leads, in turn, to the consideration or'the d~namic demands made upon the machine mechanisms, as a matter of primary concern. After a brief discussion of the e l e m e n t a r y methods of calculation of dynamic s t r e s s e s , this book goes into the mathematical methods of determining the kinematic relationships (path, velocity, acceleration) for some frequently used mechanisms (crank and slide: oscillating arm: double crank drive; elliptical gears: offset critnk-,: G e n e v a d r i v e s - e x t e r n a l and internal) and gives guidance on the methods used in the design of the cam itself for cam drives. In this connection, the computation of the various courses of motion is fully d e m o n s t r a t e d and instructively explained by meam, of numerous examples. A m o n g other topics treated further on in the book are: forces in the cam drive, choice of suitable cam followers, loading along the cam path. The numerot,s diagrams and numerical tables, set out for dimensionless parameter',. make it easy quickly to determine the reqt, ired quantities. T h e author i> internationally recognized through his extensive publications, and can look back on a decade of practical work in the field of development of automatic machines. He has tried, a b o v e all, in this work to meet the needs of the busy and preoccupied engineer, in a small industrial concern, who is dependent upon his own resources and who, on the one hand, has not the opportunity to study the many scientific publications appearing in the last decade, and. on the other hand. al_,,o has no access to a modern c o m p u t e r for the computational determination of the dirnensions or" cam drives and gears, taking into account all the parameters involved.
