In turning of steels, continuous chips are occurred easily. In this case, a chip breaker is usually used for breaking of continuous chips. However, in high speed turning under finishing conditions, low feed rate and small depth of cut, continuous chips are not able to be broken easily. Then, a new chip breaker was designed in order to find out a more effective chip breaker than the commercial chip breaker in turning. A circular cylinder of SS400 was turned by the tool with this chip breaker. And then, circular cylinders of the other steels i.e. SCM440, SUS304, S55C, SK5 were further turned by the tool with this chip breaker. It was found that this chip breaker was almost effective to five kinds of steel i.e. SS400, SCM440, SUS304, S55C, SK5. However, there is a little differences in the configuration of the chip obtained in turning between SS400 and SCM440, SUS304, S55C or SK5. There seems to be a possibility of some other chip braking mechanism existing in turning of SCM440 etc.. So, in turning of four kinds of steel i.e. SCM440, SUS304, S55C, SK5 by the tool with this chip breaker, the mechanism of chip breaking was investigated. And then, the effective part for the chip breaking on this chip breaker is investigated in order to design a new chip breaker applicable to wide range of the cutting conditions. The mode of the chip breaking is divided into seven types. Each part of this chip breaker has an effect on these types of chip breaking.
