硬脆材料的缓进给半塑性化磨削

SemiDuctile Regime Grinding of HardBrittle Materialby Creep Feed Method

分析了用缓进给方法实现硬脆材料半塑性化磨削的机理，提出了衡量半塑性化磨削效果的破碎率指标，介绍了实验方法和实验结果，对实验结果进行了分析比较。实验结果表明，在普通磨床上可实现硬脆材料的半塑性化磨削，采用缓进给磨削方法可以显著地提高半塑性化磨削的效果。

In this paper,the semiductile regime grinding mechanism by creep feed method is analysed.A new fracture ratio is defined to measure the effect of semiductile regime grinding.The experimental method and the experimental equipment are presented.The experimental results are analysed and compared.The experimental results show that the semiductile regime grinding of hardbrittle material can be carried out in a universal grinding machine tool,and the grinding effect can be improved remarkably by the creep feed method.
