    Abstract: AE的感測技術已被使用在非破壞性檢測中,可透過監測訊號觀察當材料若破裂或受到應力時所發出的AE訊號,且AE的監測技術應用已使用在加工過程監測,而在學術界的學者也將AE sensor應用在機台加工監測上,在製造業中,AE的技術應用已被建立成為線上即時偵測系統。在磨床工具機中,填塞效應是造成砂輪磨耗普遍現象之一,填塞效應是表示磨床加工中工件切屑黏著於砂輪磨料與黏著劑之間,而這現象會導致砂輪切削能力惡化與極大的磨削力,並且會增加機台振動與溫度變化,因此辨識填塞效應的影響是磨床中一個重要的議題,我們也將藉由本論文的研究,利用 AE sensor 訊號去進行探討與研究,在磨床工具機中發生填塞效應現象所造成的影響,並藉由AE訊號得知磨床加工之機台狀況,最終希望應用於磨床工具機上以便執行線上監控目的,達到 AE 填塞效應預警系統,減少機台加工誤差,並提升磨床加工精度。
    Acoustic Emission technique is used for non-destructive testing of materials. We can monitoring acoustic emissions when the material failure or stress produced it. The AE monitoring has application in process monitoring. Many authors deal with the application of AE sensor for process monitoring. In recent years, AE application is more common used in manufacturing to be on-line monitoring systems.Grinding wheel loading is a common phenomenon of grinding-wheel wear. Its meaning grinding chips adheres to the space between grains and bonding materials. The wheel loading would leads to worsening wheel cutting ability and excessive force. It also increases vibration and temperature. Identification of wheel loading is an important issue for grinding processes. This thesis will investigate the wheel loading phenomenon in grinding processes. Then an AE sensor signal will be integrated to monitor the grinding wheel loading and improve the grinding accuracy of the grinding machine tools.
