In steady cutting condition, the cutting force consists of static and dynamic components. The dynamic component is considered to be available for identifying the cutting process, because it is in close relation to the process of chip formation. In order to investigate this relation in detail, in this report, the cutting force in turning of workpiece made of steel was investigated, when varying the tool geometry, which may have considerable effects on the chip formation. The frequency analysis of the dynamic component was also carried out. Through the experiments, the effects of tool geometry on the dynamic component, the proportion of each frequency component, the relationships between the dynamic component and the finished surface roughness and so on were investigated. As a result, the following conclusions can be drawn. (1) The amplitude and frequency of the dynamic component of cutting force ate affected greatly by the tool geometry. (2) The dynamic component of cutting force consists of those derived from the chip formation process and natural frequendy component of the tool system. (3)'The dynamic component of cutting force has considerable effects on the finished surface roughness and also on the limiting depth of but.
