9451979沙利文这项建议旨在通过提供注塑成型过程变量的现代控制来丰富GMI学生的聚合物加工经验。目前在聚合物加工实验室进行的注塑成型研究实现了机电控制的使用，这在说明工艺变量和零件质量之间的基本相互作用方面令人满意。增加注塑成型实验，允许使用微处理器自适应控制隔离更广泛的参数选择，将使学生为工业中常见的典型聚合物加工情况做好准备。此外，拟议的设备将能够与计算机集成制造(CIM)环境对接，从而进一步增强GMI的聚合物加工和CIM计划。拟议设备的使用将延伸到所有各级中学和中学后教育。初级和高级机械和制造系统工程专业的学生将获得注塑成型经验，这将增强他们对工艺变量和零件质量之间的理论关系的理解。他们还将获得与其工作经验相适应的微处理器控制经验。在制造工艺入门课程中，GMI的所有一年级工程专业学生都将受益于所建议的设备方面的经验。最后，与首席调查员一起工作的高中女性和少数族裔学生将接触到现代聚合物加工设备，这肯定会激励她们继续追求科学、技术和工程方面的教育。

9451979 Sullivan This proposal seeks to enrich the polymer processing experience of students at GMI by providing modern control of process variables in injection molding. Current injection molding investigations conducted in the polymer processing laboratory implement the use of electromechanical controls, which are satisfactory in illustrating basic interactions between process variables and part quality. The addition of injection molding experiments which allow for the isolation of a wider selection of parameters using microprocessor adaptive control will prepare students for typical polymer processing situations seen in industry. Further, the proposed equipment will be capable of interfacing with a computer integrated manufacturing (CIM) environment, allowing for further enhancement of both the polymer processing and the CIM programs at GMI. Use of the proposed equipment will extend through all levels of secondary and postsecondary education. Junior and senior level Mechanical and Manufacturing Systems Engineering students will be provided with injection molding experiences which will enhance their understanding of theoretical relationships between processing variables and part quality. They will also receive microprocessor control experience appropriate to their work experience. All freshman engineering students at GMI will benefit from experiences on the proposed equipment during the course of Introduction to Manufacturing Processes. Finally, high school women and minority students working with the Principal Investigator will be exposed to modern polymer processing equipment certain to inspire them in the pursuit of further education in science, technology, and engineering.
