An industrial robot is a general purpose, and computer controlled manipulator consisting of several rigid links connected in series by revolute and prismatic joints. A mechanical manipulator can be modeled as an open-loop articulated chain with several rigid bodies (links) connected in series by either revolute or prismatic joints driven by actuators. The relative motion of the joints results in the motion of the link that positions the end-effectors in a desired orientation. In most of the applications, the spatial description of the end-effectors of the manipulator with respect to a fixed...

Minimum weight, long fatigue life & adequate film thickness are some of the key design objectives in the optimum design of rolling element bearing(REB). The design approach by considering bearing envelope, fatigue life & wear life results in a low cost bearing. The weight, dynamic load capacity & Elasto-hydrodynamic(EHD) minimum film thickness of bearing is considered as some of the important design objectives. In this book the above design objectives are optimized by using single objective & multi-objective optimization approach along with some realistic kinematic constraints. In the light...

The industry's most significant demand is to produce a component from hardened work piece material with reasonable dimensional tolerance and surface quality. Owing to the successful metal removal, improved surface quality, and dimensional precision, the turning of hardened steel (beyond HRC 45) within a dry environment has acknowledged significant interest as compared to conventional grinding. The hard turning within a dry environment is one of the suitable metal removal methods to control the machining constraints viz. environmental pollution and turning cost. This book provides an in-depth...
