| 摘 要： | 对某切刀矩时工作后出现的裂纹失效进行了分析。着重讨论了在磨削加工中形变应力、热应力和组织应力对切刀成形后的影响，提示了切刀在磨削加工后产生应力集中从而导致失效，提出了预防措施。

| Abstract: | Failure of martenaite stainless steel cutter after short term use was analyzed. The effect of deformational stress, thermal stress and structural stress during grinding process were discussed. It was pointed out that stress concentration after grinding process of cutter caused failure. Measures are proposed. |
