The Problems: Steady improvements in machine tool technology equipment, processes, and quality standards have outstripped the practical capabilities of traditional manual measurement of products. This creates three urgent problems for Piedmont Technical College's MTT program (and many MTT programs): problems of quality (students can no longer measure reliably to expected tolerances), problems of complexity (current equipment cannot even measure some of the newly-important dimensions), and problems of quantity (traditional measurement to more precise tolerances takes too long, allowing fewer rather than more such activities of our students). The Objective. To alleviate these problems through creation of a Precision Machining Measurement Center which contains fifteen pieces of equipment within five systems designed to measure linear, surface, angular, coordinate, and optical dimensions of machined products. The Methods. To redesign all seventeen current MTT courses (and add an 18th) to: (a) teach and reinforce application of this equipment in all courses; (b) redesign student projects to include explicit, graded in-process measurement of products (to supplement current end-process measurement); and (c) modify capstone courses to expect students to independently select and use appropriate measurement equipment. These activities will, in effect, add quality measurement to the curriculum's current emphasis on quality production. The Impact. Eight integrated activities will answer three questions: how much, and how, did the MTT instructional program, and with what impact? We will disseminate the PMMC model statewide through presentations, a report and the S.C. ATE Center for Excellence, and nationally through presentations and letters to the chairs of all 233 similar MTT programs.

问题：机床技术设备、工艺和质量标准的稳步改进已经超过了传统手工测量产品的实际能力。 这给皮埃蒙特技术学院的MTT项目带来了三个紧迫的问题（和许多MTT程序）：质量问题（学生无法再按照预期公差进行可靠测量），复杂性问题（目前的设备甚至不能测量一些新的重要尺寸），以及数量问题（传统的测量更精确的公差需要太长的时间，允许更少，而不是更多的学生这样的活动）。 目标。 为了缓解这些问题，我们创建了一个精密加工测量中心，该中心包含五个系统中的十五件设备，旨在测量加工产品的线性，表面，角度，坐标和光学尺寸。 方法。 重新设计所有17门现有的MTT课程（并增加第18门），以便：（a）在所有课程中教授和加强这种设备的应用;（B）重新设计学生项目，以包括明确的、分级的产品过程中测量（以补充目前的最终过程测量）;以及（c）修改顶点课程，以期望学生独立选择和使用适当的测量设备。 这些活动实际上将在课程目前强调的高质量制作之外增加质量衡量。 影响。 八个综合活动将回答三个问题：有多少，如何，做了MTT教学计划，并与什么影响？ 我们将通过演讲，报告和S.C.在全州范围内传播PMMC模型。ATE卓越中心，并在全国范围内通过介绍和信件给所有233个类似的MTT计划的主席。
