Tool condition monitoring in milling using sensor fusion technique

In this work, the response of sound pressure and cutting force during machining of Hybrid aluminium composite alloy was investigated to predict the condition of multipoint cutting tool. The machining process is carried out for fresh, working and dull tool with optimum parameters. During machining, the sound pressure and cutting force are measured using microphone and Milling tool dynamometer. The response from sensors during machining process was acquired with NI USB 6221 DAQ card and monitored using LabVIEW. The acquired signals are fused together and the fused data given as input to the fuzzy inference system and the output of which is used to assess the condition of the tool.
