Course Description
This course teaches the fundamentals of computerized manufacturing
technology. It builds on the solid-modeling skills developed in the Introduction
to Engineering Design course. Students use 3-D computer software to solve design
problems. They assess their solutions through mass propriety analysis (the
relationship of design, junction, and materials), modify their designs, and
use prototyping equipment to produce 3-Dmodels. The course includes these integrated
concepts:
- Computer Modeling: Students use 3-D software for mass
property analysis.
- Computer Numerical Control (CNC) Equipment:
Students develop an understanding of the operating procedures and programming
capabilities of machine tools.
- Computer-aided Manufacturing
(CAM): Students convert computer-generated geometry into a program
to direct the operation of CNC machine tools.
- Robotics: Student
program robots to handle materials in assembly-line operations.
- Flexible
Manufacturing Systems: Teams of students design manufacturing work cells
and tabletop factories to solve complex problems that arise in integrating
multiple pieces of computer-controlled equipment.
