heal.abstract	The problem of parameterization of the hydraulic shape of the inner surface of the bucket is handled using modern polynomial regression techniques for 3-Dimensional surfaces (Nurbs). The outline of the bucket rim and its lateral surface are represented by a number of 18 control points that can be moved independently. This technique achieves the formation of a smooth surface without	en
