Measurements of transient cutting force are very often required for analyzing of the transient phenomenon in cutting or detecting tool chipping. However, with most existing tool dynamometers which detect cutting force through the strain, accurate measurements of transient cutting force cannot be expected becauce of insufficient frequency characteristics or time lag. This paper treats with the proposal of a new method to measure the transient cutting force. In this method, cutting force is calculated by means of a digital Fourier analyzer from the output of a tool daynamometer and the transfer funcution, which has been identified in advance under the same setup as that of the foregoing cutting test. The assessment tests have revealed that thus calculated cutting force is extremely close to the real value regardless of the dynamic rigidity of the tool dynamometer. This method is also applicable for accurate detection of acceleration of a simple system.
