摘要

在磨齒加工的眾多方法中，因蝸桿砂輪磨齒為連續分度創成，效率非常高，成為現今發展的重點之一。過去傳統機台透過傳統齒輪箱達成修整齒面動作，機構複雜且繁瑣。現在自控技術進步，所以可用高自由度的數控機台，透過電子齒輪箱達成多軸同動的加工路徑。
　　本論文根據實際機台建立創成磨齒機加工數學模型，並利用電子齒輪箱可針對各進給軸加入特性曲線作路徑修整的特色，配合多軸同動的高自由度機台，達成複雜加工路徑齒面修整的模擬。
本研究利用實際磨齒機台的機械設定，模擬創成式蝸桿砂輪磨齒機加工後齒輪齒面，研究結果可做為齒面修形的基礎。

The generating gear grinding with grinding worm is a high efficiency gear tooth form finishing process by continuous indexing generating.
　　Mathematical model for the generation of the gear grinding machine is established according to the real gear grinder in this thesis. The motion of each axis in the mathematical model is derived according to the electronic gear box (EGB) function in the controller of grinder. Four specialized curve tables, which are used to make tooth flank modification, are also included in the mathematical model.
　　The developed simulation software can be applied to obtain the simulated ground surface which is generated with the machine settings of the real gear grinder. The result of this study is the basis of further study on the tooth profile modification.
