Integrating Modern Coordinate Metrology into the Industrial and Manufacturing Systems Engineering Curriculum Through an Enhanced, Automated, and CAD-Directed Coordinate Measuring

三坐标测量机（CMM）是制造业中最强大和最广泛使用的测量仪器之一。几乎没有工作场所的尺寸不能用适当装备的CMM测量。本提案的目的是通过获得电动探头、自动探头更换系统、模拟扫描探头和Valisys CAD/CAM软件包来增强计量实验室中现有的CMM。增强的CMM系统将允许将现代化、自动化和CAD指导的坐标计量集成到工业和制造系统工程（IMSE）课程中。它将直接影响学生，特别关注代表性不足的群体，参加大一课程，IMSE-101制造工艺，以及高级课程，如IMSE-384数控（NC）系统，IMSE-407聚合物加工和IMSE-480计算机集成制造（CIM）系统。该项目的任务是（1）完全自动化CMM系统，以允许在CAD/CAM/CIM环境中进行灵活的检测和集成，（2）将CMM与NC，CIM和聚合物加工实验室电子连接，以允许实时检测反馈，通过Valisys软件关闭这些过程的生产循环，以及（3）建立CAD指导的检查系统，以允许通过CAD/CAM系统进行智能检查，以验证设计，将公差与软测量相结合，模拟检查程序，并将CMM与新兴技术（例如逆向工程，快速原型，和快速加工。已计划进行几项实验室实验，并将在上述IMSE课程中进行。增强的CMM系统还将用于开发计量学、几何尺寸公差和质量方面的新课程。它将为学生提供进行本科研究和独立学习，发表论文和技术论文的机会。

Coordinate Measuring Machines (CMMs) are one of the most powerful and widely used metrological instruments in the manufacturing industry. There is virtually no workplace whose dimensions cannot be measured with a properly equipped CMM. The objective of this proposal is to enhance an existing CMM in the Metrology laboratory by acquiring a Motorized Probe Head, an Automatic Probe Exchange System, an Analog Scanning Probe, and a Valisys CAD/CAM software package. The enhanced CMM system will allow for the integration of modern, automated, and CAD-directed coordinate metrology into the Industrial and Manufacturing Systems Engineering (IMSE) curriculum. It will directly impact students, with particular attention given to underrepresent groups, enrolled in the freshman course, IMSE-101 Manufacturing Processes, and upper level courses such as IMSE-384 Numerically Controlled (NC) Systems, IMSE-407 Polymer Processing, and IMSE-480 Computer Integrated Manufacturing (CIM) Systems. The tasks of the project are to (1) fully automate the CMM system to allow for flexible inspection and integration in a CAD/CAM/CIM environment, (2) electronically connect the CMM with NC, CIM, and Polymer Processing laboratories to allow for real-time inspection feedback to close the production loop of these processes via the Valisys software, and (3) establish a CAD-directed inspection system to allow for intelligent inspection through the CAD/CAM system to verify design, combine tolerancing with soft gaging, simulate inspection procedures, and integrate the CMM with emerging technologies such as reverse engineering, rapid prototyping, and rapid tooling. Several laboratory experiments have been planned and will be implemented in the aforementioned IMSE courses. The enhanced CMM system will also be used to develop a new course in metrology, geometric dimensioning & tolerancing, and quality. It will provide students with opportunities for conducting undergraduate research and independent study, and publishing theses and technica l papers.
