摘要

切削力矩在切削的過程中為重要的加工參數，且有許多商業化的儀器可用以精確測量切削加工過程中的切削力矩。然而，該些商業化的量測儀器價格昂貴，且安裝和實際的應用過程可能會限制其執行性能。因此，近年來已有發展間接的量測方法來估算切削力矩。其中，從主軸系統獲得的參考信號，由於直接且顯著的與工具機的實際切削過程的切削力矩相關，而受到關注。雖然現有的演算法和制定方式對於間接估算切削力矩顯示出合理的估計結果，這些方法在實際應用中仍然有限，主要是因為假設的是條件良好的主軸系統。但是，有缺陷(ill-conditioned)的主軸系統常存在於真正的加工系統。因此，為在實際切削過程中為了準確估算等效切削力矩，主軸系統的運動特性的確是要了解的。因此，本研究針對實際的主軸系統進行實驗研究，結論主軸系統的物理模型。再將此主軸系統的物理模型應用於端銑刀鑽孔加工上，進而估算出端銑刀在鑽孔過程中所受到的切削力矩。

Cutting torque is an important factor for cutting processes. Many commercialized apparatuses can accurately measure the cutting torque, but they are expensive, and installation and application constraints can limit their performance. The reference signals obtained from the spindle system of a machine tool have attracted considerable attention because they may be directly and significantly related to the cutting torque during the actual cutting process of a machine tool. This paper presents experimental results of a study on an actual spindle system; a physical model of the system is also presented. An estimation algorithm is developed to estimate the cutting torque during the drilling operation using an end-mill cutting tool. Experimental results obtained using a CNC tapping machine show the feasibility of the proposed approach.
