Stamping Practice: High Performance Stamping

Description

This book clearly shows and describes the basics of high-performance stamping, tool design and high-performance technology systems. It shows the current status of processes, tools as well as machines and equipment for stamping technology. Design guidelines and characteristic parameters from practice provide the design of tools. The mathematical determination of the influencing variables, material-technical basics and functional correlations support the selection of machines. The numerous calculation examples and complete solution paths make this book very suitable for self-study.
