| 摘 要： | 通过对脆性材料磨削加工损伤机理的分析,说明磨削方向与脆性材料强度分布的各向异性有关.提出一种外圆磨床磨削圆柱类脆性材料的运动模式,并对磨削加工试件进行强度试验、Weibull统计分析和断口显微分析,结果表明对于外圆磨削,改变磨削加工方向,脆性材料工件的轴向抗拉强度可以提高30%.

| Abstract: | Brittle materials are characterized by grinding direction related strength anisotropy attributed to the dual population of grinding induced micro-cracks.The paper analysis the form mechanism of grinding crack in ceramics materials.It presents aspects of an innovative material-adapted kinematics variant,which corresponds to an enhancement of characteristic flexural strength of about 30% in comparison to conventionally ground brittle samples. |
