A common problem in teaching undergraduate manufacturing courses involving machining is the difficulty to arrange appropriate machining experiments for a number of possible reasons such as: limitations on laboratory facilities, insufficient support of technicians, large size of class, limited funds for running the costly experiments, and safety considerations. Lack of physical understanding about the machining undermines the learning effectiveness in this course. The goal of the proposed project is to develop a virtual reality (VR) machining laboratory integrated with computer graphics animation, process knowledge and predictive machining models. The specific objectives are to help students in obtaining important hands-on" machining experience, enhance their physical understanding of machining principles, and promote their latent learning capability to the maximal possible extent. In such a virtual environment, all the students have a ' one-to-one" opportunity to "physically" operate various kinds of machines (both conventional and CNC) on their own and observe and study the on-line simulated dynamic machining performance by choosing different process parameters. The significance of the proposed project is that it can be used as a national model for future machining laboratories with the advantages of significant cost-effectiveness, knowledge-integrated interactive learning environment, great flexibility for various machining operations and, C-based software for easy portability. The results should be very attractive to other colleges for setting up a similar system and should have a significant impact on current teaching practices of manufacturing courses. The effectiveness of the VR system at different development stages will be evaluated through four consecutive teaching semesters of the course ME322 Manufacturing Processes (offered every semester). As a national model for future machining laboratories, the results of the proposed project will be publicize d through conferences, publications and the World Wide Web.

一个常见的问题，涉及机械加工本科制造课程的教学是很难安排适当的加工实验的一些可能的原因，如：实验室设施的限制，技术人员的支持不足，大规模的类，有限的资金运行昂贵的实验，和安全考虑。 缺乏对机械加工的物理理解会破坏本课程的学习效果。 该项目的目标是开发一个虚拟现实（VR）加工实验室集成计算机图形动画，工艺知识和预测加工模型。具体目标是帮助学生获得重要的实际操作经验，增强他们对机械加工原理的物理理解，并最大限度地促进他们的潜在学习能力。在这样一个虚拟环境中，所有的学生都有一个“一对一”的机会，“物理”操作各种机器（包括传统的和数控）自己和观察和研究在线模拟动态加工性能，通过选择不同的工艺参数。建议的项目的意义是，它可以作为一个国家模式，为未来的加工实验室具有显着的成本效益，知识集成的互动学习环境，各种加工操作的灵活性和，基于C的软件，易于移植的优势。 研究结果对其他高校建立类似的教学体系具有一定的参考价值，对当前制造类课程的教学实践具有重要的借鉴意义。VR系统在不同开发阶段的有效性将通过连续四个学期的课程ME322制造工艺（每学期提供）进行评估。作为未来加工实验室的国家模型，拟议项目的结果将通过会议，出版物和万维网公布。
