Abstract

The main purpose of a tool condition monitoring (TCM) system is to ensure reliable monitoring of the cutting tool edge condition. The system should be simple to configure for different cutting conditions and the obtained results should be interpreted in an unambiguous way. Implementation of monitoring system involves finding solutions to a number of sub-tasks such as selection of the type of signal, definition of sampling rate, selection of patterns, signal filtering, methods for the selection and ranking of features, the process of learning and creation of knowledge base, user friendly procedure for operating TCM, and methods of reacting on established tool condition. Based on these considerations, a modular concept of tool condition monitoring system is proposed. The concept has been tested on machining processes with variable material hardness and cutting depths.
