DM 814 - Rapid Mechanical Design

Rapid Mechanical Design addresses all aspect of mechanical design, including consideration for end-of-life issues, with the focus and emphasis of the course being on rapid product development. In this course, the participants will be introduced to the various state-of-the-art methodologies and off-the-shelf tools and facilities for rapid design. The course will have an introductory section on a limited set of classical design topics in order to prepare the students for the in-depth discussion of the advanced topics on rapid prototyping.

Course Overview

Rapid Design addresses all aspect of mechanical design, including consideration for end of- life issues, with the focus and emphasis of the course being on rapid product development. In this course, the participants will be introduced to the various state-of-the art methodologies and off-the-shelf tools and facilities for rapid design. The course will have an introductory section on a limited set of classical design topics in order to prepare the students for the in-depth discussion of the advanced topics on rapid prototyping. The introductory topics will include: Manufacturing Management Strategies, Concurrent Engineering, Conceptual Design, and Design for X. The advanced rapid-design topics are categorized into virtual and physical prototyping. Virtual prototyping topics include: Geometric Modeling (including major CAD software packages), Computer-Aided- Engineering (CAE) Analysis, Engineering Optimization, Design of Experiments, and Virtual Reality. Physical prototyping topics include: Introduction to Polymerization, Sintering, Casting, and Chemical Machining, Material-Additive Layered Prototyping (including Photolithography, Sintering, Deposition, Lamination, and Laser-Induced- Fusion Based Rapid-Prototyping Systems), Material-Removal-Based Prototyping, and Reverse Engineering.

Activities & Schedule

The first module of this course will focus on accelerating the implementation of classical design methodologies, while the second module will deal with rapid-product prototyping issues. The instructors expect that each student will both be prepared for and attend all of the class sessions and participate fully in the group project. Active participation is critical since especially during Module 2 of the course class time will be allocated to the discussion of the group project and other outstanding issues and concerns. In addition to marking of the group and individual projects there will be an individual class-participation grade (about 20%) that will be based upon the student’s questioning of the material covered and contribution to in-class discussions.
