Performance Analysis of High Speed Tool Wear Detection System Based on DC Two Terminal Methods

This study presents performance analysis of in-process tool wear detection system which uses the tool-work thermo-electromotive force (E.M.F) by the measurement circuit system as a signal-gauge in face milling. Depending on the width of tool flank wear, the cutting edge signal increases according to the variations of the electrical resistance due the increase of the contact area between tool-work and workpice. In this experiment, different milling conditions are presented such as indexable inserts with a variation of tools wear, chip breaker and water-soluble cutting fluid which has not been evaluated until now. Thus, the objective of this research is to evaluate the performance of this high speed tool wear detection system.
