Abstract Due to precision, flexibility, simplicity in construction, easy control, higher speed and lower energy consumptions, servo presses have recently become popular in metal forming applications. Servo press technology combines the advantages of hydraulic and conventional mechanical presses without their drawbacks. This study presents design, construction and demonstration of a servo crank press system for metal forming operations. The research involves kinematics and motion optimization, dynamic modeling, structural design and analysis, servo motor selection, automation and control, and operational performances of the servo press. The press used in this work has a load capacity of 50 ton and stroke capacity of 200 mm. Firstly, optimized trajectories of ram scenarios are generated. Then dynamic modeling using Lagrange approach is presented. Next structural model is constructed, and Finite Element Analysis (FEA) of press parts are performed within safety limits. A servo motor with a reduction unit is selected based on dynamic model. After that a new automation system is developed, and Cascade Feed-Forward (CasFF) control is applied. Moreover, four motion scenarios (crank, dwell, link, and soft motion) are employed for the performance assessment of press. Finally, the dynamic model is verified by the experimental results. The research study is carried out under support and grant of an industrial project, aiming to provide know-how to industry and researchers. Key Words: Servo crank press, metal forming, motion design, dynamic modeling, system control

Servo Motors and Industrial Control Theory is the only text focused on the fundamentals of servo motors and control theory. Graphical methods for classical control theory have been augmented with worked examples using MatLab and Mathcad to reflect the reality of the way engineers solve control problems in the field today. State variable feedback control theory is introduced clearly and simply, with practical examples that help students approach what can be seen as complicated problems with confidence. This updated second edition includes expanded discussion of Nyquist and Root Locus stability criteria and the role of sensors, as well as new Mathcad examples. A range of parameters are introduced for each servo control system discussed, making this book a comprehensive learning tool for students and an accessible information resource for control system designers who want to keep their knowledge up-to-date.

Now in its second edition, Industrial Control Electronics continues to provide readers with an extraordinarily comprehensive understanding of instrumentation, process control, and servomechanisms - all in a single volume! In addition to detailed discussion of modern components, circuits, devices and control techniques used in today's industrial automated systems, this edition features two all-new chapters on DC and AC variable speed drives plus a generic approach to PLCs that employs the Allen-Bradley SLC-500 as a sample. As in the first edition, the book begins with an overview of the control loop while subsequent sections allow readers to explore individual elements of the loop in depth. This logical organization allows the book to be used effectively in a variety of programs, including: Electromechanical Technology, Instrumentation (Process Control) Technology, Automated Manufacturing Systems (AMS), Electronics Technology, and Industrial Maintenance.

The authors and editors of this Handbook have attempted to fill a serious gap in the professional literature on industrial automation. Much past attention has been directed to the general concepts and philosophy of automation as a way to convince owners and managers of manufacturing facilities that automation is indeed one of the few avenues available to increase productivity and improve competitive position. Seventy-three contributors share their knowledge in this Handbook. Less attention has been given to the "What" and "How" of automation. To the extent feasible and practical within the confines of the pages allowed, this Handbook concentrates on the implementation of automation. Once the "Go" signal has been given by management, concrete details-not broad definitions and philosophical discussions-are required. To be found in this distinctly different book in the field are detailed parameters for designing and specifying equipment, the options available with an evaluation of their relative advantages and limitations, and insights for engineers and production managers on the operation and capabilities of present-generation automation system components, subsystems, and total systems. In a number of instances, the logical extension of current technology into the future is given. A total of 445 diagrams and photos and 57 tables augments detailed discussions. In addition to its use as a ready reference for technical and management personnel, the book has wide potential for training and group discussions at the college and university level and for special education programs as may be provided by consultants or by "in-house" training personnel.
