ENG-SCI 51: Computer-Aided Machine Design
Course Overview
ENG-SCI 51 is an introductory course in the design, fabrication, and assembly of mechanical and electromechanical devices. Topics include engineering graphics and tolerances; manufacturing processes (3D printing, laser cutting, lathe & CNC milling); structural design and material selection; machine elements and two-dimensional mechanisms; DC motors; design methodology.
Emphasis is placed on hands-on work and team design projects using professional solid modeling CAD software and numerically controlled machine tools. This course will expose you to interesting material, challenge your thinking, and provide skills useful for professional practice.
