This paper deals with the dynamic component of cutting force in turning. In order to have high-efficiency and -precision in the cutting process and to verify cutting mechanism in more detail, it is very important to recognize the properties of cutting force, it is especially important to check the methods for adaptive control due to automation of the cutting process, e.g.tool wear, surface roughness, chatter vibration control, etc. For the purpose of investigating the possibility of inprocess recognition of the cutting process, the dynamic component is analyzed by the cut-off frequency at each cutting condition, as is the relationship between the dynamic component and the surface roughness. The results which obtained were as follows ; 1) The characteristics of the tool system have a large effect on the dynamic component of cutting force. 2) The dynamic component of cutting force is proportional to feed rate. 3) The frequency and amplitude of the dynamic component of cutting force is in relation to over hang length, cutting speed, and feed rate. 4) It is possible to recognize the cutting process by the method of cut-off frequency analysis. The dynamic component of tangential cutting force is in relation to surface roughness qualitatively in a cut-off frequency of 0-2.5 KHZ.
