Painstakingly revised, the second edition of Cam Design and Manufacturing Handbook brings together the latest cam design technology, proper cam design and manufacturing procedures, and recent cam research results in one volume that is indispensable to the design and manufacturing of cam-follower systems.
Covering both introductory and more advanced topics in depth, topics discussed in this edition include a treatment of shape-preserving spines for valve cams, equations for calculation of 3-D globoidal cams, multi-DOF cam-follower system models, equations for the calculation of compensation cams that completely cancel inertial torque on a camshaft, and equations to model the deliberate impact of a cam follower against a valve seat or a hard-stop.
