This project is transforming the way students acquire engineering design and manufacturing knowledge by integrating the use of three axis desktop CNC (Computer Numerical Control) equipment into an undergraduate engineering curriculum. The initial focus of the project is on the first two years of the undergraduate engineering curriculum. The program is creating a new hands-on integrated design and manufacturing curriculum that uses CNC machines both as a design task and as a tool for product manufacture. Computer programming, mathematics, and physics are also being integrated into the curriculum. Specifically, students are required to write computer programs to control the machine.Students at the junior and senior years are also involved because they use their design skills to help develop the inexpensive easily manufactured CNC machine tool. Because the tool development is part of the project, maintenance and upgrades are handled as part of the undergraduate curriculum.The inquiry-based curriculum creates a hands-on experiential education for the students. As a result of this experience students have an increased knowledge of engineering design, an increased analysis capability, and much more self-confidence. The evaluation of these outcomes is performed an external evaluator. Motivation is being studied using the "Situational Motivation Scale". Self-efficacy and higher cognitive achievement is being studied using the "Motivated Strategies for Learning Questionnaire" and the "Metacognitive Awareness Inventory".The project is disseminating results by providing machine designs and curriculum to all interested universities, two-year colleges, and high schools.

该项目将三轴桌面 CNC（计算机数控）设备的使用整合到本科工程课程中，从而改变学生获取工程设计和制造知识的方式。该项目最初的重点是本科工程课程的前两年。该项目正在创建一个新的实践综合设计和制造课程，使用数控机床作为设计任务和产品制造工具。计算机编程、数学和物理也被纳入课程中。具体来说，学生需要编写计算机程序来控制机器。三年级和四年级的学生也参与其中，因为他们利用自己的设计技能来帮助开发廉价且易于制造的数控机床。由于工具开发是项目的一部分，因此维护和升级作为本科课程的一部分进行处理。基于探究的课程为学生创造了实践的体验式教育。通过这次经历，学生们增加了工程设计知识，提高了分析能力，并且更加自信。这些结果的评估由外部评估员进行。正在使用“情境动机量表”来研究动机。正在使用“学习动机问卷调查”和“元认知意识量表”来研究自我效能和更高的认知成就。该项目正在通过向所有感兴趣的大学、两年制学院和高中提供机器设计和课程来传播结果。
