The mechanism of chipping of sintered cutting tools in interrupted cutting is clarified through finite element analysis and microscopic observations. It is verified that the deterioration of the tool structure is the significant cause of tool chipping. Two chipping prediction method are proposed bas的翻译：正在翻译，请等待... 什么意思？中文翻译英文，英文翻译中文，怎么说？

这一机制的碎裂的烧结切割工具的切割中断通过有限元分析和微观澄清意见。经证实,恶化的重要原因是刀具结构的工具碎裂。两个碎片预测方法的建议基于上述调查结果。
