磨削异型曲面的变性共轭原理

本文说明曲面的“可磨性”是个重要概念。从“可磨性”入手，分析了异型曲面一般是不可能的，只能通过磨出近似是而非曲面的办法来取代，取代的中心问题是要设法使近似曲面能满足工程上的精度要求。文中提出的变性共轭原理，就是为了解决这个问题，使磨出的近似曲面达到最佳逼近所要求的异型曲面效果。通过实例验证，变性共轭原理目前在刀具复杂曲面磨削方面的应用是成功的。

THE PRINCIPLE OF ANOMALOUS CONJUGATION FOR GRINDING THE CURVED SURFACES WITH SPECIAL SHAPE

This paper shows that the "grind ability" of curved surface is an important conception. To make clear the grindability of curved surface as the point of departure, in this paper that the curved surfaces with special shape are generally ungrindable is analysed. So they can only be substituted by the approximate curved surfaces ground out, and the key problem is how to. Grind out the approximate curved surfaces satisfying the accuracy grade in engineering fore the required special shaped curved surf aces. In order to slove this problem, the principle of anomalous conjugation is presented in this article. Applying this principle can make the ground approximate curved surfaces substitute the required curved surfaces optimumly. It has been tested and verified that the principle of anomalous conjugation has been applied successfully now in the area for grinding some complex curved surfaces on cutting tools.
