摘要: 於機械加工中,研磨為最後的精修加工程序,攸關工件之表面品質和精度。若以不當之研磨參數,可能使砂輪磨耗甚至導致工件表面發生燒傷,此時會造成工件尺寸精度失真、表面狀況不佳等情形發生。為了提升加工品質與效率,導入線上即時研磨燒傷監控系統,使現場操作員能在適當時機停止加工,並做進一步的加工參數調整或砂輪修銳,以維持工件品質與精度。 本研究使用聲射感測器(AE sensor)進行工件燒傷之監測,並配合動力計(dynamometer)觀察磨削力之變化以及表面粗糙度量測。將燒傷對應之聲射訊號進行比對分析,且透過快速傅立葉轉換(Fast Fourier Transform, FFT)分析頻域變化。 實驗結果顯示過大的前後進刀量、切深、床台線速度與過低之砂輪線速度皆會造成工件表面燒傷,其對應之表面粗糙度也隨之惡化。研磨過程中以Y軸方向(砂輪徑向)磨削力最大,X軸方向(砂輪切線方向)次之,當燒傷時X與Y軸方向磨削力達5牛頓與7牛頓以上。此外,聲射訊號能有效反映出材料內部的塑性變形與熱膨脹現象,於燒傷時有明顯增加之現象,其方均根閾值(threshold)界於0.15至0.2伏特之間,且磨削力與聲射能量之間的變化趨勢非常相似。 聲射訊號透過FFT處理後,各組實驗中在頻率100kHz、230kHz與240kHz處皆出現高峰,其中又以頻率100kHz之能量值在燒傷發生時能量明顯大增。因此相較於磨削力訊號與聲射訊號方均根值,觀察聲射頻譜訊號對於燒傷有較佳之分辨能力。
