Sheet Metal Forming

parts, and 
7. the effects of the process on the environment.
These topics are addressed in two companion volumes 
Sheet Metal Forming—Funda-
mentals
and 
Sheet Metal Forming—Processes and Applications
. Principles are de-
scribed, and major emphasis is placed on the latest developments on the design of sheet 
forming operations, equipment and tooling. 
In 
Sheet Metal Forming—Fundamentals
, the role of sheet metal forming in manu-
facturing has been introduced in Chapter 1. Chapter 2 gives the classification and de
-
scription of sheet metal forming operations. The fundamentals of plastic deformation, 
i.e. metal flow, flow stress of materials, testing methods to determine flow stress and 
formability are discussed in Chapters 3, 4, and 5. Chapters 6 and 7 cover the significant 
process variables materials and friction. The introduction to deep drawing is discussed 
in Chapter 8. Chapters 9, 10, 11, and 12 discuss the characteristics and operations of 
various sheet metal forming presses (hydraulic, mechanical, servo-drive) and cushion 
systems.

viii / Preface
In 
Sheet Metal Forming—Processes and Applications
, Chapters 1 and 2 cover blank-
ing, and bending. Process modeling and its applications are discussed in Chapter 3 as 
well as in several other chapters, where appropriate. Chapter 4 reviews progressive and 
transfer die forming. Relatively new technologies, i.e. warm forming, forming of ad-
vanced high strength steels (AHSS) and hot stamping are discussed in Chapters 5, 6, 
and 7, respectively. Processes that are related to sheet forming such as sheet and tube 
hydroforming, roll forming, and high velocity forming are covered in Chapters 8 9, 10, 
and 11. Special sheet forming operations spinning, incremental forming and mechani-
cal joining are discussed in Chapters 12, 13, and 14. Sensors and die materials are criti-
cal for practical application of sheet forming technology and they are discussed in 
Chapters 15 and 16.
The preparation of this book was possible through extensive efforts by many friends, 
associates and students of the editors who authored and co-authored many of the chap-
ters. We would like to thank them all for their very valuable contributions.
We would like to thank Ms. Linda Anastasi, Administrative Assistant of the Center 
for Precision Forming (CPF – www.cpforming.org), who revised the chapters several 
times, Mr. Xi Yang and Manan Shah at CPF who assisted in the editing of some chap-
ters and Mr. Doug Dragoo of Cincinnati Inc. who reviewed Chapter 15 on Bending and 
made valuable suggestions. We would also like to thank our families, who offered us 
enormous support and encouragement throughout the preparation of this book. 
Finally, we would like to gratefully acknowledge the financial support from member 
companies of CPF and especially from the National Science Foundation (NSF) that 
helped us summarize the results of sheet metal forming research, conducted over the 
years at The Ohio State University.
