SYSTEMS engineering, RAPID prototyping, DEFENSE industries, MANUFACTURING processes, and LIKELIHOOD ratio tests
In 2007, John Young, then-Under Secretary of Defense for Acquisition, Technology and Logistics, mandated the use of "competitive prototyping" strategies in defense acquisition. Further, Department of Defense Instruction 5000.02 includes considerations for prototyping in the acquisition strategy. A 2017 memorandum circulated by Young lists five prototyping benefits, which are expected to "reduce technical risk, validate designs, validate cost estimates, evaluate manufacturing processes, and refine requirements." However, a process to assess whether, and to what extent, a prototype will be or has been successful in achieving these benefits is not currently in use by the Department of Defense. Because cost increases and schedule extension downsides are inherent in prototyping, such an assessment is critical. This research proposes an approach for assessing the likelihood of achieving expected prototyping benefits based on identifying the factors yielding these benefits as well as their relative weights.

MACHINING, MANUFACTURING processes, PERMANENT magnets, MACHINE tools, STATORS, POWER capacitors, and HEAT transfer
This paper presents a design process and a detailed multiphysics analysis of an axial-flux permanent-magnet synchronous machine for large-power direct-drive applications. The machine in this paper is 130 kW at 26 r/min with a dual-stator inner-rotor structure. A stator core that is assembled with segmented and prewound teeth is first proposed and applied in a large-power axial-flux permanent-magnet machines (AFPMs). Through this method, the challenges of manufacturing large-diameter AFPMs can be solved. A novel water-cooling system is embedded in the machine to transfer the heat. In addition, the assembling procedure and the manufacture process are also proposed, and a novel distributed follower bearing is used to reduce the deformation and stress of the rotor disk. Finally, based on the multiphysics design, a prototype machine is manufactured and tested. The experiment results match well with the finite-element analysis. [ABSTRACT FROM AUTHOR]
A direct-slicing approach might improve the accuracy and quality of small, complex parts produced with rapid prototyping technology. An application software based on direct slicing for rapid prototyping was used on the foundation of PowerSHAPE models. Lines, conic arcs and cubic bezier curves were adopted as the basic elements describing the direct-slicing contours. Moreover, a scheme to carry out subdivided software development was proposed. A picture (PIC) format file was selected as an interface for the slicing data, and a macro-AutoSection software, which collects the direct-slicing contour data of arbitrary complex computer-aided design models and provides power to produce the direct-slicing PIC files, was developed. On the above basis, an application software called PDSlice based on direct-slicing data processing was developed for the commercial selective laser sintering machine HRPS-III, which was made at the Huazhong University of Science and Technology (HUST), P. R. China. The major input and output interfaces as well as the PIC model reconstruction method of the PDSlice are described. Furthermore, a batch of direct-slicing polymer parts were successfully fabricated with the selective laser sintering machine. The application example shows that the accuracy and surface finish of three-dimensional complex curvature surface parts fabricated with the application software system based on a direct-slicing format were better than the application software system based on a stereolithography (STL) format.
