APPLYING SIGNALS OF CONTROL SYSTEM IN TOOL WEAR MONITORING

Open structure of modern digital controls open up new possibilities and prospects in monitoring of machining systems and processes. In many cases, the combination of digital plant signals and internal data of the machine control system, along with advanced methods of signal analysis can replace the external control systems. The integration of process control software module into the machine control system allows fast reactions should there be any process disturbances, without any additional hardware expansion. This paper studies the sensitivity of signals contained in the control system to the cutting tools wear processes in face turning.
