This revision aims to address changes that have taken effect since the publication of the second edition. The most significant change has been in the attitude of industry to concurrent engineering. In 1987, mostly lip service was paid to it; today, it has become general practice in most competitive corporations. In the second edition , the author discussed this as the manufacturing system. In the third edition it becomes the focal point. | ME 4563 Introduction to Manufacturing Processes Fall 2005 College of Engineering Arkansas State University ME 4563 Fall 05 Dr. S.
