Abstract

The article considers а method for real-time forecasting the cutting tool life, considering as a blow-up mode its operation. The method based on the selection of a log-periodic component in the audio signal accompanying the cutting process. The model of this component contains as the main parameter the time taken as the tool life. To ensure the process control efficiency, when making a decision to stop the cutting process, the residual tool life is determined, which is equal to the difference between the tool life prediction and the current part processing duration.
