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

坐标测量机(CMM)是制造业中功能最强大、应用最广泛的计量仪器之一。几乎没有一个工作场所的尺寸不能用配备得当的三坐标测量机来测量。这项提议的目的是通过购买电动探头、自动探头交换系统、模拟扫描探头和Valisys CAD/CAM软件包来增强计量实验室现有的三坐标测量机。增强的坐标测量机系统将允许将现代、自动化和CAD指导的坐标计量学整合到工业和制造系统工程(IMSE)课程中。它将直接影响新生课程、IMSE-101制造工艺以及IMSE-384数字控制(NC)系统、IMSE-407聚合物处理和IMSE-480计算机集成制造(CIM)系统等高级课程的学生，特别关注代表不足的群体。该项目的任务是(1)使三坐标测量机系统完全自动化，以便在CAD/CAM/CIM环境中实现灵活的检测和集成；(2)将三坐标测量机与NC、CIM和聚合物加工实验室进行电子连接，以便通过Valisys软件实现实时检测反馈，以关闭这些工艺的生产循环；(3)建立CAD指导的检测系统，以通过CAD/CAM系统进行智能检测，以验证设计、将公差与软测量相结合、模拟检测程序，并将CMM与诸如逆向工程、快速原型和快速模具等新兴技术相集成。已经计划了几项实验室实验，并将在上述管理、科学和经济管理系统的课程中实施。增强的三坐标测量机系统还将用于开发一门新的计量学、几何尺寸和公差测量以及质量课程。它将为学生提供进行本科生研究和自主学习的机会，并发表论文和L技术论文。

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.
