抄録

<p>A study to investigate contact detection and recognition of the cutting state by means of the acoustic emission (AE) technique in ultra-precision turning is presented. Detection of accurate cutting-edge position was achieved through investigation of the contact limit between the cutting edge and workpiece through use of the AE technique. Moreover, to recognize the cutting state, changes in AE signals instigated by corresponding changes in the cutting condition were monitored. In the contact-detection experiment, contact between the cutting edge and workpiece was detected with a cut depth of 10 nm. Likewise, in the cutting state recognition experiment, AE signal waveforms were observed to demonstrate changes corresponding to changes in the cutting state. These results confirm the feasibility of using the AE technique in cutting state monitoring experiments.</p>
