隨著科技的進步，工業各領域為了追求更好的產品性能，大量使用超硬合金來做材料。此種材料目前的加工方式仍是以磨削為主。然而這些材料的機械特性往往對於磨削加工帶來一定的困難度。且能允許的磨削參數範圍非常狹窄。加工中使用的砂輪也是昂貴的超級磨粒為磨料。在近年來的研究中證實了將超聲振動應用在傳統加工上，材料移除率、切削力、切削溫度都因而改善，同時也延長了刀具的壽命。但是超聲振動加工的機制傳統加工有明顯的不同。而超聲振動應用在傳統磨削加工上應該也會有相同的效果。因此本文希望對於超聲振動輔助磨削超硬合金的加工特性進行理論與實驗的研究，探討超聲輔助磨削和傳統磨削在加工超硬合金時其加工機制之差異，實驗將以材料移除率、表面粗糙度、磨削力、比磨削能及工件的表面狀況作為判斷指標。同時嘗試使用一般用的碳化矽砂輪。希望提供一個較高加工品質、較低成本且加工限制少的加工法。
