Abstract
Section titled āAbstractāThe purpose of this paper is to investigate the effect of control factors on the ablation characteristics by using Taguchi method and adopt self-tuning fuzzy-PID controller design to tune the moving-wire velocity.The characteristics of the sawing system include ingot profile variance and cutting rate.The optimal ablation parameters are tension force, wire velocity, cutting force, width of the kerf.The ) 3 ( 4 9 L orthogonal array, signal-to-noise (S/N) ratio and analysis of variance (ANOVA) are employed to analyze the effect of these ablation parameters.Using the optimal ablation parameters, we accomplish the diamond multi-wire sawing (DMWS) high-speed control and synchronous dynamic tracking of the main roller under the moving wire bow angle holding.The simulation results show that the cutting rate is direct proportional to moving wire speed and cutting force.Also, the passive main roller can almost track the active main roller synchronously and dynamically under the sustained bow angle within 5.7 ļÆ in 7 forward and 5 backward wire-moving.
