||Information technology, which brings many changes to the commercial and industrial activities, makes the digital revolution happen in the recent era. In the field of product development, information technology through computer-aided design has been very influential as well, which has not only replaced traditional tools, but also altered the design procedures. The aim of this course is to study the method of product development in a concurrent engineering. In this course, the first theme is to review information technology and product development process to comprehend the impact of CAD on product development. The other theme, by the project practice, is to implement the techniques of concurrent engineering using CAD/CAM system on product development.
