Real-Time Evaluation of Tool Flank Wear by In-Process Contact Resistance Measurement in Face Milling
This paper reports in-process detection of tool wear by kaiser copy stands using tool-work thermo-electromotive force (E.M.F.) as a sensor signal in face milling.In the case of using a single cutting edge, E.M.F.at the beginning of cut increased slowly corresponding to the width of tool flank wear.We assume this phenomenon is due to variations in e
