目前大部分熱熔拉法所製作的光纖探針是由人工操作機器製作而成，生產的光纖探針品質管制不易，造成在實驗時所得到的結果會有不穩定的狀況。本論文建構一光纖探針熱熔拉法成形理論模型來模擬對特定機型熔拉機在熔拉光纖時，探討光纖的長度與半徑的變化及幾何外型的改變，根據所設定的加工參數，模擬出光纖探針之外型尺寸形狀、探針尖端幾何形狀及尖針直徑。
同時進行靈敏度分析，找出光纖探針熱熔拉法加工模擬程式，哪一種參數對模擬所的到的實驗值有比較明顯的影響力。本文以靈敏度分析分別探討探針直徑、熔拉速度、硬拉值等三個加工參數對探針長度跟外型之影響。
最後，本文中利用靈敏度分析之觀念找出對製程參數影響性較大的參數之參數範圍，且將所得到的參數範圍結果提供給田口法當做控制因子水準的參考依據。並以田口法及變異數分析各控制參數對製程的貢獻度，並求得光纖探針目標值最長長度之較佳的控制參數組合。

At present, most of the optical fiber probes that are produced by melt-drawn methods are made by manual-operated machines, leading to the difficulty in quality control and unstable experiment result. This paper constructs a theoretical model of fiber probe melt-drawn method to investigate into the changes of the length, radius and geometrical shape of the optical fiber probe during the simulation of hot-melting the fiber probe by Sutter instrument of specific model.
At the same time, by means of sensitivity analysis, a simulation equation of optical fiber probe processing by means of melt-drawn method can be established, so as to investigate into the parameters having a more obvious influence towards the experimental values acquired by the simulation. By means of sensitivity analysis, the effect of the processing parameters such as the diameter, melt-drawn speed and hard-pull value towards the length and shape of the optical fiber probe can be investigated.
Finally, this paper adopts the concept of sensitivity analysis to find the range of the parameters that carries a greater impact to the processing parameters. The acquired result of the parameter range is referential to Taguchi’s Method as the control factor level.Furthermore, Taguchi’s Method and variances are employed to analyze the level of contribution of respective control parameters towards the processing, so as to ask for a better control parameter combination for the longest length of the optical fiber probe target value.
