This Major Research Instrumentation (MRI) award provides funding for the development of manufacturing equipment that will incorporate the laser-based and welding-based deposition processes with multi-axis computer numerical controlled machining. Specifically, this award funds the acquisition of an automatic welding torch changer, a two-axis rotary table, and a PC-based motion controller. These items, along with already existing hardware components at the Research Center for Advanced Manufacturing, such as: a Nd:YAG laser of 1 kW in power, a four-axis computer numerical controlled machining center, a six-axis robot, two powder feeders, and two computer controlled welding machines, together make multi-fabrication manufacturing equipment capable of building an entirely new class of components of monolithic or functionally graded composition. The equipment will be capable of fabricating parts that are characterized by complex internal and external geometrical features, as well as by high dimensional accuracy and good surface quality. Additionally, this award supports the development of an information system that automates and coordinates the exchange of information between all of the involved elements of this equipment. This information processing system consists of a number of modules, such as: solid data exchange module, adaptive slicing module, process planning module, process sensing and control module, and a module for the automatic generation of path planning for welding torches, laser head, and cutting tools.This equipment will enhance the research, training, and educational capabilities at Southern Methodist University's Research Center for Advanced Manufacturing in the area of layered-based manufacturing. The multi-fabrication system will be an unparalleled candidate for a "Mobile Part Hospital" that will contribute to the strengthening of America's military readiness. The availability of hardware and software both acquired and developed through this project will provide "hands-on" experience and research facilities for the undergraduate and graduate students, as well as engineers from local industry. As the project involves various aspects of engineering science and practice in nontraditional manufacturing processes, welding, design, computer control systems, interfacing, sensing, signal processing, control, and software development, students will be exposed to the related concepts, principles, methods, software and hardware. This exposure will provide the impetus for addressing more challenging cross-disciplinary manufacturing development problems. Layered-based manufacturing will become a major graduate thrust of the School of Engineering at Southern Methodist University.

该重大研究仪器 (MRI) 奖项为制造设备的开发提供资金，这些设备将基于激光和基于焊接的沉积工艺与多轴计算机数控加工相结合。 具体来说，该奖项资助购买自动焊枪更换装置、两轴旋转工作台和基于 PC 的运动控制器。 这些项目以及先进制造研究中心现有的硬件组件，例如：功率1千瓦的Nd:YAG激光器、四轴计算机数控加工中心、六轴机器人、两台送粉机和两台计算机控制的焊接机共同构成了多制造制造设备，能够构建全新类型的整体或功能分级组合的组件。该设备将能够制造具有复杂的内部和外部几何特征、以及高尺寸精度和良好表面质量的零件。 此外，该奖项还支持信息系统的开发，该系统可自动执行和协调该设备所有相关元件之间的信息交换。 该信息处理系统由多个模块组成，如：固体数据交换模块、自适应切片模块、工艺规划模块、过程传感与控制模块、焊枪、激光头、路径规划自动生成模块等。该设备将增强南卫理公会大学先进制造研究中心在分层制造领域的研究、培训和教育能力。 该多制造系统将成为“移动零件医院”的无与伦比的候选者，这将有助于加强美国的军事准备。 通过该项目获得和开发的硬件和软件将为本科生和研究生以及当地行业的工程师提供“实践”经验和研究设施。 由于该项目涉及非传统制造工艺、焊接、设计、计算机控制系统、接口、传感、信号处理、控制和软件开发等工程科学和实践的各个方面，学生将接触到相关概念、原理、方法、软硬件。 这种接触将为解决更具挑战性的跨学科制造开发问题提供动力。 分层制造将成为南卫理公会大学工程学院研究生的主要研究方向。
