课程教学目标（ Objectives ） This course is an introduction to different metal

forming processes such as rolling, extrusion forging, drawing, sheet metal forming and deep drawing. It will give an overview of the main metal forming processes but also provide some understanding of the complicated relations between a forming process and the product qualities. The course will begin with the development of the fundamentals of metal forming and material behavior. The emphasis throughout will be on the metal forming processing and equipment.

课程基本要求（ Basic Requirements ）
