초록

The continuous chip generated in cutting process deteriorates workpiece, tool ,and machine tool system. It is necessary to treat this continuous chip in ductilematerial machining condition for stable cutting. This paper deals with the chipcontrol method using acoustic emission(AE) signal in pure copper turningoperation. AE raw signals, root mean square(RMS) signals and wavelettransformed signals measured in turning process are introduced to analysis forchip patterns. With analysis of AE signals, it is obtained that the produced chippatterns are correlated with the specified AE signals which are transformed byfuzzy pattern algorithm. By this experimental investigation, the chip patterns canbe classified at significant level in pure copper machining process and controlledfrom continuous chips to reduced‐length stable chips
