Analysis on Ground Surface Damage of Quartz Fiber-Reinforced Quartz Composites

Article Preview

Abstract:

The grinding experiments of Quartz Fiber-Reinforced Quartz Composites(QFRQC) were conducted on MK9025 NC optical curve grinding machine. Grinding forces were measured by KISTLER dynamometer and the morphologies of the grinding surface were observed with Hatchi S-4800 SEM. In this paper, the effect of grinding orientation on the ground surface damage of QFRQC was discussed. Grinding orientation has a big influence on the ground surface damage. When grinding orientation is perpendicular to fiber orientation, the surface of the workpiece is poor; By contrast, when grinding orientation is parallel to fiber orientation, the surface of the workpiece is good; when grinding is on the fiber end-faces, the surface of the workpiece is best.
