  • Robust Design of Dynamic System when Ideal Function’s Parameters are Unknown
    DEStech Transactions on Computer Science and Engineering, 2017
    Co-Authors: Ya-chi Lee
    Abstract:

    Robust design is an important method to reduce the effect of noise factors and unit-to-unit variation in order to improve the product quality and which leads to higher customer satisfaction. The robust design of dynamic system is used to find the optimal control factor settings so that the measured response is closest to the Ideal Function. In this paper, a mathematical formula based on the quality loss Function is derived for optimizing the robust design of unlinearized dynamic system. The example of high-precision positioning device is provided to demonstrate the implementation and effectiveness of the proposed method.

  • Universally Composable Secure Just Fast Keying Protocol
    Computer Engineering, 2011
    Co-Authors: Wang Yi-fang
    Abstract:

    Aiming at the redundancy of Just Fast Keying(JFKi) and the absence of its forma proof,a new Lightly Just Fast Keying(LJFKi) is proposed.Through the contrast analysis,it is found that the protocol proved is one-third shorter than the natural protocol,which has higher communication efficiency and is more convenient for the sensitive network to communication payload.The proposed protocol can realize secure session Ideal Function and afford Universally Composable(UC) security by proving with universally composable secure model.

  • Dimensional quality optimisation of high-speed CNC milling process with dynamic quality characteristic
    Robotics and Computer-Integrated Manufacturing, 2005
    Co-Authors: Tzeng Yih-fong, Jean Ming-der
    Abstract:

    Abstract High-speed CNC milling is becoming an indispensable process for manufacturing industry. To increase the process versatility, flexibility, and robustness, Taguchi dynamic approach coupled with a proposed Ideal Function model is employed to develop an optimal high-speed CNC milling process with high-dimensional quality. Additionally, a test sample with three typical geometries including square, circle, and triangle essentially representing the geometrical variations in the mould and die products was designed for use throughout the experiments. Experimental results show that the dimensional accuracy of the machined product has been greatly improved by the optimal conditions obtained by Taguchi dynamic approach. Moreover, the product can be easily machined to the desired dimension simply by adjusting the programmed dimension according to the mathematical equation by linear regression analysis of confirmed results.

  • optimization of the high speed cnc milling process using two phase parameter design strategy by the taguchi methods
    Jsme International Journal Series C-mechanical Systems Machine Elements and Manufacturing, 2005
    Co-Authors: Yihfong Tzeng, Fuchen Chen
    Abstract:

    High speed, high quality and short delivery are the development trend of the manufacturing industry. In this paper, the Taguchi dynamic characteristic theory was used coupled with proposed Ideal Function models under a two-phase optimization strategy. The main objective of this work is to develop optimized machining parameters in the high-speed milling process with the characteristics of high machining efficiency and geometrical accuracy, and wide applications. The experimental results showed that the machining time can be effectively reduced using the designed optimal parameters obtained from the first phase of the strategy. The process variance was only 63.96% of the initial conditions, and the robustness of the process was increased 1.56 times. The control factors having the most influences on the machining time and the robustness of the CNC milling process in order of importance were identified as cutting speed, number of teeth, and feed per tooth. The dimensional relationship between the input and output of the milling process under the first-phase optimized conditions was derived as Y=1.001090M. Therefore, according to this model, final adjustment to the input programmed dimension can be made in phase two to obtain the Ideal machining accuracy.

  • a simple approach for robust design of high speed electrical discharge machining technology
    International Journal of Machine Tools & Manufacture, 2003
    Co-Authors: Yihfong Tzeng, Fuchen Chen
    Abstract:

    Abstract The paper presents a simple approach for optimizing high-speed electrical-discharge machining (EDM). The approach begins with designing the Ideal Function of an EDM system coupled with Taguchi methods for process optimization. It has been proposed that the Ideal Function has a linear relationship between the input signal (intended dimension) and the output response (product dimension). This model seeks to develop a robust machining process enabling high precision and accuracy of machining a product. In this study, a two-step optimization strategy has been applied. The first step is to reduce the Functional variability of the EDM system to enhance process robustness. The second step is to increase the machining accuracy by adjusting the slope of the best-fit line between the input signals and the output responses. Experimental results have shown that the use of the proposed model is simple, effective, and efficient in the development of robust and high-quality EDM machining processes.
