中文摘要 | 本研究是一種選用K型材質的尖鼻負稜主刃碳化鎢車刀片,當刀尖在工具磨床上預先磨有一磨耗量後,針對碳纖維複合材料(CFRP)做車削研究。研究當中除了量測三軸切削力外,並利用切削過程中,刀面與工件之摩擦面積,以計算出摩擦力。其次配合有限元素分析技術(FEA),利用Abqus™軟體及逆向分析法(Inverse method),以預測磨耗尖鼻負稜碳化鎢車刀切削碳纖複材時其刀尖之表面溫度。最後與美工外線儀器所量測的結果作比較,結果顯示量測值與預測值很接近。 |
英文摘要 | Temperatures of the carbide tip's surface when turning Carbon-Fiber-Reinforced-Plastics (CFRP) materials with a K type sharp main cutting edge tool considered wear is investigated. The frictional forces and heat generated in the basic cutting tools are calculated by using the measured cutting forces and the theoretical cutting analysis. The heat partition factor between the tip and chip is solved by using the inverse heat transfer analysis, which utilizes temperature on the carbide tip's surface measured by infrared as the input. The carbide tip's surface temperature is determined by finite element analysis (FEA, Abaqus™ software) and compared with temperatures obtained from experimental measurements by infrared. Good agreement demonstrates the proposed model. |
