Course Description

This is a graduate level course that teaches fundamental principles and theoretical backgrounds underlying CAD/CAM systems. It covers a broad range of topics including: the current development, applications and future trends in CAD/CAM, mathematics behind free-form curves/surfaces, reverse engineering, parametric feature-based modeling, direct modeling, 3 D printing, basic principles of integration of CAD/CAM, basic principles of CIMS and FMS. Meanwhile guiding students, especially international students to make good use of parametric feature-based software widely used in industry to express design ideas, develop their comprehensive ability to solve complex engineering problems.

Learning Outcome

At the end of this course students should be able to:

(1)   have a big picture about CAD/CAM technology; know the current development and future trends in CAD/CAM.

(2)   organize and discuss academic issues in CAD/CAM accurately and professionally.

(3)   grasp mathematics behind free-form curves/surfaces so that students could be able to create 3D models of curves/surfaces mathematically on the computer.

(4)  understand the basic principles, methods and applications of current advanced CAD/CAM technology, including reverse engineering, parametric feature-based modeling, direct modeling, 3 D printing etc.

(5)   understand the principles of integration of CAD/CAM, the basic principles of CIMS and FMS.

(6) make a good use of parametric feature-based software widely used in industry to express design ideas, and cultivate students’ comprehensive ability to solve complex engineering problems.

By receiving a thorough fundamental theoretical training and mastering CAD/CAM software, students will be well equipped and more confident to solve difficult problems in design and manufacturing.
