Book Description
1. 1 Preliminary Concepts A cam mechanism is a mechanical system consisting of three basic components: a driving element, called the cam; a driven element, termed the follower; and a fixed frame. Sometimes, an intermediate element is introduced between the cam and the follower with the purpose of improving the mechanism performance. This element is called the roller because function is to produce a pure-rolling relative motion be tween the cam and the follower. The purpose ofa cam mechanism is the transmission of power or information. In applications concerning power transmission, the main good to be transmitted is force or torque; in applications ofinformation transmission, the main good transmitted takes the form of motion signals. Most modern appli cations of cam mechanisms, to be described shortly, are of the former type. Cam mechanisms used for information transmission were traditionally found in measuring instruments. With the advent ofmodern microprocessor-based hardware, this typeof application is becoming less common. Nevertheless, cam mechanisms are still used in a wide spectrum of applications, especially in automatic machines and instruments, textile machinery, computers, printing presses, food-processing equipment, internal combustion engines, control systems, and photographic equipment (Prenzel, 1989). In the design of cam mechanisms, the engineer performs several activities, namely, task definition, synthesis, analysis, optimization, and dynamic simulation. These tasks do not always follow this order. In fact, some loops may appear in the foregoing tasks, such as those illustrated in Fig. 1. 1. 1.

Book Description
Despite advances in robot technology, in which industrial manipulators have replaced mechanisms, cam mechanisms still find important industrial applications in the textile, food processing and manufacturing industries. This book is a modern, up-to-date treatise on the important subject of cam synthesis. Cam mechanisms have been studied from different points of view, namely, kinematic synthesis, dynamic synthesis, analysis, design, optimization and manufacturing. This book is oriented to the kinematic synthesis of cam mechanisms in a unified framework, i.e. that spatial, spherical and planar cam mechanisms are integrated in the same formulation. Traditionally, the synthesis of the three types of cam mechanisms has been approached using independent formulations. With a unified formulation, both well known types of cam mechanisms, as well as novel cam mechanisms can be synthesized, as shown in the book. Moreover, since all the design parameters are considered in a unified framework, the optimization theory of cam mechanisms can be applied systematically, i.e. the criteria applied for the optimization of planar cam mechanisms, which can be found to some extent in the literature, can be complemented in order to provide general criteria for the optimization of spherical and spatial cam mechanisms. The underlying philosophy of the book has been to exploit sound mathematical and kinematical tools of analysis and synthesis that could be used only with the available current software and hardware. The approach and tools introduced in this book can assist the designer in producing a broad spectrum of mechanisms than those described in the book. This will be an invaluable reference for engineering designers.

Book Description
This book gathers the proceedings of the 15th IFToMM World Congress, which was held in Krakow, Poland, from June 30 to July 4, 2019. Having been organized every four years since 1965, the Congress represents the world’s largest scientific event on mechanism and machine science (MMS). The contributions cover an extremely diverse range of topics, including biomechanical engineering, computational kinematics, design methodologies, dynamics of machinery, multibody dynamics, gearing and transmissions, history of MMS, linkage and mechanical controls, robotics and mechatronics, micro-mechanisms, reliability of machines and mechanisms, rotor dynamics, standardization of terminology, sustainable energy systems, transportation machinery, tribology and vibration. Selected by means of a rigorous international peer-review process, they highlight numerous exciting advances and ideas that will spur novel research directions and foster new multidisciplinary collaborations.
