【Abstract】 This paper presents a new algorithm of adaptive step lengths and path interval on parametric coordinate system.As the algorithm considers the radius of the curvature difference between different cutter contact points,so it can improve machining efficiency and the accuracy of the finished surface. This algorithm is suitable for machining sculptured surface. A method of calculating cutter location point is also presented in this paper.更多还原
