Abstract: The purpose of this paper is to investigate the effect of ablation parameters on the ablation characteristics for the fixed diamond multi-wire sawing by using Taguchi method. Meanwhile, using the optimal ablation parameters, we accomplish the cutting dynamic analysis and controller design of the diamond multi-wire sawing system. In this paper, we apply the Chemical Mechanical Polishing (CMP) theorem to derive the ingot profile and cutting rate equations of the diamond multi-wire sawing system. The characteristics discussed in this paper include ingot profile variance, cutting rate. The ablation parameters are tension force, wire velocity, cutting force, width of the kerf. The orthogonal array, signal-to-noise (S/N) ratio and analysis of variance (ANOVA) are employed to analyze the effect of these ablation parameters. In the meantime, we use the optimal ablation parameters to accomplish the controller design of the diamond multi-wire sawing system, include diamond high-speed control of the main roller in the cutting system, cutting rate control and the moving wire bow angle holding.

Abstract: The purpose of this paper is to accomplish facial recognition and destiny foreseeing in real-time for a specified person using fuzzy classification technique. This system uses CCD camera to take a picture of a specified person in an appropriate distance, and then uses a skin color detection method to extract the facial area by separating skin color scope. After the human face is searched, we locate the facial contour by using the ellipse template method. Find out the locations of eye and lip on the human face, and then to get the complete shape of eye and lip separately by using image processing technique and morphology. In this research, we classify the sample template into some classes by using fuzzy classification technique in advance to accelerate real-time task of the facial recognition, 3D face modeling and destiny foreseeing. Afterward, we apply the-Norm/-Norm minimization criterion to calculate the certificate degree of the recognized face and estimated destiny.
