[論文] Acoustic Emission을 利用한 工具破損 및 Chipping의 探知에 關한 硏究

다국어 초록 (Multilingual Abstract)

This study was investigated the feasibility of AE application on in-process detection of tool fracture and chipping.<br/>
Carbon steel SM45C workpiece with longitudinal slots was turned interruptedly on a lathe.<br/>
AE RMS signal at tool fracture was observed and also the tangential force and the feed force were measured to compare with AE RMS signal. The sudden high level AE signal was observed at the time of tool fracture, the levels of tangential force and the feed force at the time of fracture decrease considerably.<br/>
In chipping, high level AE signal was observed but there were no changes of cutting force.<br/>
Peak AE RMS squared is proportional to the area of toolfracture and resultant force.<br/>
Fracture model of tool fracture is proposed as<br/>
v_P= C₁E₁F (△A)^0.5<br/>
and peak AE RMS shows strong correlation with the fracture parameter F(△A)^0.5.
