Second, it was discovered that the cutting tools were abraded severely with the amount of titanium increasing after cutting test and analyzing the cut performance at different cutting condition of cast iron bars containing different titanium content.

• 其次,采用在铸铁中加入一定量的钛,并浇注成棒料,进行不同钛含量棒料切削试验,分析不同钛含量铸铁在不同切削条件下的切削性能情况。 结果发现,随着铸件中钛含量的增高,刀具的磨损越严重;
