| Abstract: | In the process of sawing 20MnCr5 round bar in a factory, the saw blade is easy to fracture. The reasons for easily fractured of the saw blade were analyzed by means of observation and analysis by optical microscope (OM) and scanning electron microscope (SEM). The analysis results showed that the fracture reason of the saw blade was the tooth collapse of the sticking knife in the process of 20MnCr5 machining. In view of this kind of machining defect, the corresponding improvement measures were put forward. |
