Laser Materials Processing

该项目通过开发激光材料加工实验室，向本科生介绍广泛的材料加工概念。一台700瓦的二氧化碳激光系统最近被捐赠给了该部门。然而，为了将该系统有效地集成到本科实验课程中，需要一个工件运动系统。本项目在该激光系统中增加了一套计算机数控(CNC)的工件运动系统。随着激光系统的数控增强，材料加工如热处理、激光连接、表面改性和合金化等也被引入。该实验室主要用于焊接冶金、制造工艺和材料科学课程。此外，该实验室还广泛用于计算机辅助制造课程，其中介绍了计算机-机器接口主题，以及数控编程概念和CAD/CAM集成。

This project is introducing undergraduate students to a broad range of materials processing concepts through the development of a laser materials processing laboratory. A 700- watt CO2 laser system was recently donated to the department. However, in order to effectively integrate the system into the undergraduate laboratory curriculum, a workpiece motion system is required. This project has added a computer numerical control (CNC) workpiece motion system to this laser system. With the CNC enhancement to the laser system, materials processing topics such as heat treating, laser joining, surface modification, and alloying are being introduced. The laboratory is primarily used in welding metallurgy, manufacturing processes, and materials science courses. In addition, the laboratory is used extensively in computer-aided manufacturing courses where computer-machine interfacing topics are introduced, as well as CNC programming concepts and CAD/CAM integration.
