TL;DR: The handbook as discussed by the authors provides design engineers with up-to-date information about the many aspects of forging including descriptions of important developments made more recently by industry and/or government.
Abstract: : The handbook provides design engineers with up-to-date information about the many aspects of forging including descriptions of important developments made more recently by industry and/or government. The handbook describes suitable measures for in-process quality control and quality assurance, summarizes relationships between forging practices and important mechanical properties and compares various forging devices to aid in equipment selection. Attention is also given to describing practices for relatively new materials and emerging forging practices. (Modified author abstract)

TL;DR: In this paper, a 700 ton hydraulic press, a newly installed 500 ton mechanical press of scotch yoke design, and a 400 ton screw press were used in the study and room temperature copper upset tests were employed to determine the dynamic press stiffness, the offcentre loading ability, the flatness of ram and bolster surfaces under load and the available energy capacity at various production rates.
Abstract: This study discusses the important characteristics of forging presses and describes methods for determining them. A 700 ton hydraulic press, a newly installed 500 ton mechanical press of scotch yoke design, and a 400 ton screw press were used in the study. In all threepresseshigh-temperature ring-compression tests were used to determine the practical effect of press speed on die chilling, metalflow and load requirements. In the mechanical press, room temperature copper upset tests were employed to determine the dynamic press stiffness, the offcentre loading ability, the flatness of ram and bolster surfaces under load and the available energy capacity at various production rates.
