中文摘要 碳化鎢鑽頭硬且脆,刀具發生磨耗後若無適時的更換刀具而又繼續加工即會產生崩裂異常,因此,針對碳化鎢鑽頭建立線上刀具磨耗監控模式有其迫切性與需要性。
本論文分析螺旋鑽頭幾何並利用局部切削力的基礎,建立一套針對一般螺旋鑽頭之鑽削力模式。此模式將鑽削力分解成剪切與犁切作用,並加以探討剪切與犁切作用中比切削係數與鑽頭磨耗間之關係。
針對刀具磨耗線上監控,本文主要監測主軸馬達功率、扭矩及軸向推力,配合鑽削力模式提供一線上判認比切削係數的方法。研究結果顯示剪切作用與犁切作用之比切削係數在實際鑽削加工中可視為一常數,唯獨鑽頭磨耗對犁切作用之比切削係數有較為顯著的影響,當刀具發生磨耗時,比切削係數即會隨著刀具磨耗的增加而增加,因此,本研究結果顯示此特性可作為線上刀具監控的依據,並證實鑽削力模式在線上監控刀具磨耗應用上之可行性。


英文摘要 Because of tungsten carbide drill is hard and brittle, If the drills has worn on drilling process then it will be broken unless we replace it in time. So we must setting a on-line monitoring of drills wear system.
This paper presents a drill force model for general twist drill in accordance with analysis twist drills geometry and differential local cutting forces. These force models include edge plowing as well as chip shearing mechanisms. Further explore relation of drill wear with specific cutting coefficients. Prediction edge plowing specific cutting constant and chip shearing specific cutting coefficients which one is more sensitive during drill has worn.
This paper monitoring of drill wear using motor power、cutting torque and axial thrust, Depending on drill force model submit a on –line method identify specific cutting coefficients. Accordance with experiment result plowing specific cutting coefficients and chip shearing specific cutting coefficients is constant in general cutting process but the plowing specific cutting coefficients will obvious alteration during drill has worn, This characteristics can apply for the monitoring of drill wear system.
