提出了用电火花加工创成整体涡轮的流道曲面电极加工面造型的问题,首次将外推法中的GBS算法应用于电极曲面的造型过程中,设计得到了无干涉电火花精加工电极加工面,用算例证明了所提出算法的可行性及有效性。
In this paper, the problem of modeling the processing surface of the electrode of the flow channel surface electrode by using the spark machining is proposed. The GBS algorithm in the extrapolation method is applied to the modeling process of the electrode surface for the first time. The example shows the feasibility and effectiveness of the proposed algorithm.
