Sažetak
This paper describes a fast Fourier transformation and its application to monitoring tool wear. Describes the transformation of the collected signal during cutting from the time domain to the frequency. The introduction describes the discrete Fourie transform, DFT deficiency observed in a large number of samples. Therefore, its use in this case is fast Fourie transform. As an example shown is an indirect method for monitoring tool wear that is based on the measurement values of process variables (acoustic emission) and the relationship between tool wear and these values. Tool wear monitoring is a difficult task because many machining processes are non- linear time-variant systems, which makes them difficult to model and the signals obtained from sensors are dependent on a number of other factors, such as machining conditions.
