This Small Business Technology Transfer ( STTR) Phase II project proposes the creation of an Advanced Virtual Manufacturing Lab (AVML) for training and education on high-tech CNC machines. The key elements of the AVML are: (a) textured 3D photo-realistic virtual models of the machines and lab that include the machines' controls and moving parts; (b) semi-empirical model of the machining operation; (c) hierarchical knowledge-base for process training; (d) unstructured knowledge-base for lecture delivery; (e) natural-language human-like intelligent virtual tutors. In this phase of the research, the AVML will be completed by adding more capabilities, including 5-axis milling and collision detection between the tool and the machine, and enhancing the accuracy and completeness of the machining operation model. Furthermore, the AVML will be enhanced by incorporating Conversational Programming, different types of machine controllers, and two additional types of machines: CNC lathe and production-grade 5-axes milling machine. Pilot implementations will be conducted at a university and two community colleges. Applications of AVML include: training students to operate manufacturing machines in a safe environment, allowing students and researchers to view and interact with a near-physically accurate simulation of manufacturing machines, and optimization of the manufacturing process plan by testing various plans on the virtual machine before machining on the physical machine.Manufacturing drives innovation and is a powerful engine of economic growth. However, US manufacturers face a shortage of workers to run tomorrow's factories. The AVML will enhance the quality, accessibility, and productivity of manufacturing education and training and will advance scientific discovery and engineering analysis of manufacturing processes. Also, The AVML will enhance experimentation and learning, increase student creativity and problem-solving capability, enhance collaboration among students, teachers, and industry experts, and promote participation and equal access of underrepresented groups to manufacturing technology training. Most potential manufacturing workers do not have access to state-of-the-art manufacturing labs that can provide the required training. The AVML will enable such access. This success, in turn, will strengthen US manufacturers' competitiveness and further important US national interests.

这个小企业技术转让（STTR）第二阶段项目建议建立一个先进的虚拟制造实验室（AVML），用于高科技数控机床的培训和教育。 AVML的关键要素是：（a）机器和实验室的纹理化3D照片逼真的虚拟模型，包括机器的控制和移动部件;（B）加工操作的半经验模型;（c）用于过程培训的分层知识库;（d）用于授课的非结构化知识库;（e）自然语言的类人智能虚拟导师。 在这一阶段的研究中，AVML将通过增加更多功能来完成，包括5轴铣削和刀具与机床之间的碰撞检测，并提高加工操作模型的准确性和完整性。 此外，AVML还将通过整合对话式编程、不同类型的机床控制器以及另外两种类型的机床来增强：CNC车床和生产级5轴铣床。 将在一所大学和两所社区学院进行试点实施。 AVML的应用包括：培训学生在安全的环境中操作制造机器，让学生和研究人员能够查看制造机器的近乎物理精确的模拟并与之互动，并在物理机器上加工之前通过在虚拟机器上测试各种计划来优化制造工艺计划。制造业推动创新，是经济增长的强大引擎。 然而，美国制造商面临着工人短缺，无法运营未来的工厂。 AVML将提高制造业教育和培训的质量、可及性和生产力，并将推进制造过程的科学发现和工程分析。 此外，AVML将加强实验和学习，提高学生的创造力和解决问题的能力，加强学生，教师和行业专家之间的合作，并促进代表性不足的群体参与和平等获得制造技术培训。 大多数潜在的制造工人没有机会进入最先进的制造实验室，可以提供所需的培训。 AVML将使这种访问成为可能。 这一成功反过来将增强美国制造商的竞争力，并进一步促进美国的重要国家利益。
