| dc.description | The purpose of this work is to study the behavior of the acoustic emission (AE) signal as the cutting tool wears up to the end of its life, aiming the automatic definition of the moment to change the tool. Several turning experiments were carried out in both, finish and rough conditions, using coated carbide tools. The AE signal was acquired during the experiments and, after suitable conditioning, was stored in the computer. A discussion about the use of the mean RMS acoustic emission signal as a parameter in the evaluation of the tool condition was also done. The results were graphically plotted and analyzed. It was concluded that the AE signal is strongly influenced by the tool wear and that the cutting conditions are very important, since the signal shows a very different behavior between finish and rough turning. The main conclusion of this work is that AE monitoring is a very good way to establish the moment to change the tool, since the mean RMS of the signal shows a sharp increase close to the end of tool life in finish turning and a decrease, also close to the end of tool life, in rough turning operations. So, a criterion to the determination of the moment to change the cutting tool was established, based on the change of the AE curve slope during the tool life. | |
