一、课程的性质 《冲压模具设计与制造》是模具设计与制造专业的一门主干专业技术课,也是制造类其它专业的一门 重要选修课。它是一门将冲压成形加工原理、冲压设备、冲压工艺、冲模设计与冲模制造有机融合,综合 性和实践性较强的课程

This 90 minutes lecture to be delivered via telelink addresses a class of mit undergraduates unrolled in Engineering Design and Rapid prototyping Course. The students have been introduced to the basic optimization concepts of design variables design space, objective function, constraints and numerical search methods. Building on this elementary basis, the purpose of the lecture is to make the students aware of a reaud range of theoretical and practical issues that arise when optimization is applied in real-life engineering. To that end a gamut of topics is presented with emphasis on the qualitative exposition rather than in-depth mathematics. The topics include
