摘要：Deburring of high-precision components to their micrometer features without any damage is very important but of great difficulty as the burr-to-functionality size ratio increases. To this end, this paper proposes a new deburring method in which the micro burr should be directly removed based on ultraprecision cutting with the designed monocrystalline diamond tool. To determine the feasibility of the proposed method, this paper applies it for deburring of the precision working edge of the servo valve core. Firstly, the monocrystalline diamond tool is carefully designed by covering a variety of topics like rake angle,clearance angle, edge radius. Then, the finite element(FE) simulation was conducted to characterize the deburring performance during the removal of the micro burr produced by the single abrasive grinding. Finally, an innovative self-designed deburring system was introduced and the deburring process was evaluated in terms of cutting forces, temperatures, tool wear mechanisms and deburring quality of the working edges by experiments. The FE simulation results indicate the suitability of the proposed deburring method. Meanwhile, the experimental findings agree well with simulation results and show that ultraprecision cutting with the specialized monocrystalline diamond tool could be successfully used for deburring of servo valve core edge without any damage. This work can provide technical guidance for similar engineering applications, and thus brings an increase to the machining efficiency for the manufacture of precision components.

摘要：Explicit Data Graph Execution(edge)ISA是一种专门为类数据流驱动的分片式众核处理器而设计的指令集体系结构.相较于传统的采用控制流驱动的处理器,edge结构以超块(Hyperblock)而不是单个指令作为其执行单位,在超块内部实现数据流执行,超块之间按照推测序保持控制流执行,有利于挖掘指令级并行性.但是,edge编译器按照程序的串行执行顺序组织超块,超块间和超块内部受限于数据依赖,削弱了整个程序运行时的潜在数据级并行性和线程级并行性,不利于发挥edge分片式结构的优势.本文通过分析edge编译器超块组织的特点,结合edge结构特有的执行模型,提出一种普适性的超块组织框架来模拟edge结构上多线程运行的效果,进一步挖掘edge结构运行串行单线程程序时的指令级并行性.本文选用TRIPS微处理器作为edge结构的实例处理器,利用矩阵乘法等三个实验验证了我们所提出的框架的可行性,实验结果表明这些应用在TRIPS上获得了较好的性能提升.

摘要：The reliability of facility location problem has aroused wide concern recently. Many researchers focus on reliable and robust facility systems design under component failures and have obtained promising performance. However, the target and reliability of a facility system are to a large degree adversely affected by the edge failures in the network, which remains a deep study. In this paper, we focus on facility systems’ reliability subject to edge failures. For a facility location system, we formulate two models based on classical uncapacitated fixed-charge location problem under deterministic and stochastic cases. For a specific example, location decisions and the comparison of reliability under different location models are given. Extensive experiments verify that significant improvements in reliability can be attained simply by increasing the amount of operating cost.
